The Quartz Crisis had decimated the watchmaking industry, with the number of watchmakers in Switzerland having dropped from 1,600 to 600. Against all odds, three watchmakers at Audemars Piguet decided to develop the world’s thinnest automatic perpetual calendar movement. The project was \u003ca href=\"https:\/\/www.acollectedman.com\/blogs\/journal\/five-movements-changed-world-part-i\" title=\"Read our article on five movements that changed the world\" target=\"_blank\"\u003ecarried out in secret\u003c\/a\u003e, with the manufacture’s upper management completely unaware of what was going on.

A risk-taker who’d already released the Royal Oak a few years prior, Golay was confident that the manufacture could successfully commercialise the automatic perpetual calendar. When it was launched in 1978, the Quantième Perpetuel was the world’s thinnest automatic perpetual calendar. To put things in perspective, in 1984, only 1,066 perpetual calendars were produced in Switzerland. Of those, Audemars Piguet made 675.\u003c\/p\u003e\n\u003cp class=\"p1\" data-mce-fragment=\"1\"\u003eThough the Royal Oak often gets credit for helping Audemars Piguet survive in the wake of the Quartz Crisis, evidence suggests the Quantième Perpetuel played a much greater role.

The Quartz Crisis had decimated the watchmaking industry, with the number of watchmakers in Switzerland having dropped from 1,600 to 600. Against all odds, three watchmakers at Audemars Piguet decided to develop the world’s thinnest automatic perpetual calendar movement. The project was carried out in secret, with the manufacture’s upper management completely unaware of what was going on. The watchmakers worked in their free time, often meeting at night to discuss their work.\u003cbr\u003e\u003cbr\u003eIn 1977, they surprised George Golay, the CEO of Audemars Piguet at the time, with the finished calibre. A risk taker who’d already released the Royal Oak a few years prior, Golay was confident that the manufacture could successfully commercialise the automatic perpetual calendar. When it was launched in 1978, the Quantième Perpetuel was the world’s thinnest automatic perpetual calendar.\u003c\/p\u003e\n\u003cp\u003eA few years later, the manufacture chose to combine this innovative movement with their iconic Royal Oak cases. In 1983, they released the reference 5554, which is also designated as the reference 25554. This reference 25654 was introduced in a subsequent iteration of the concept, featuring the same parred back aesthetic as the original design. Only 800 examples of the reference 25654 were produced between 1983 and 1998, limited to just 422 in yellow gold. \u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003eAt the time, the combination of the sporty, Royal Oak case and complicated perpetual calendar movement was an unusual, forward-thinking approach by the brand, combining luxury with one of its most utilitarian pieces. In recent years, the Royal Oak Quantième Perpétuel has since been the canvas on which Audemars Piguet have experimented and redefined its perpetual calendars, introducing various unique interpretations.

The piece also features original gold stick hands, a characteristic rarely found in Royal Oak watches. The sub-dials are slightly recessed, giving the dial greater depth and texture. Additionally, the dial displays the \"Audemars Piguet\" signature in small lettering, which is only found on the earlier examples of the 25654 reference, before the brand adopted its modern signature style. \u003c\/p\u003e\n\u003cp\u003eThe gold case and bracelet are excellently finished, with chamfered, beveled and polished edges - striking the perfect balance between utilitarian function and elegant design.

It was first integrated into a wristwatch in 1925, by none other than Patek Philippe. For much of the 20th century, perpetual calendars remained scarce, on account of their niche appeal and the specialised skillset needed to design and assemble one. In the wake of the Quartz Crisis, these complicated pieces continued to be exceedingly rare, as their very purpose came under threat. Indeed, this seismic event had decimated the watchmaking industry, with the number of watchmakers in Switzerland having dropped from 1,600 to 600.\u003c\/p\u003e\n\u003cp\u003eHowever, against all odds, the perpetual calendar experienced a revival towards the end of the 20th century. Within the span of seven years, between 1978 and 1985, Audemars Piguet, Vacheron Constantin and Patek Philippe all introduced their own ultra-thin, automatic perpetual calendars. These were amongst the first perpetual calendars to be produced in a series. This marked a fundamental departure with the past, when each of the manufactures from “Holy Trinity” of watchmaking would only have produced a few dozen of these pieces a year, at the very most. This signified a renewed faith in the future of complicated horology.\u003cbr\u003e\u003cbr\u003eWhilst Audemars Piguet were the first out of the gate in 1978, it is believed that Vacheron Constantin unveiled their automatic, ultra-thin perpetual calendar wristwatch in 1983. Rather frustratingly for Patek Philippe, this was two years before they came out with their own reference 3940. As a staring point, Vacheron Constantin used the mythical Jaeger-LeCoultre 920, which was the thinnest automatic movement in the world when it came out in 1967. They then reworked a perpetual calendar module from Dubois-Depraz, a famed module manufacturer, who has supplied Patek Philippe, Audemars Piguet and Vacheron Constantin, amongst others. The end result was the Caliber 1120 QP, which still remains in production to this day, albeit in an updated form.\u003c\/p\u003e\n\u003ch6\u003eA skeletonised approach\u003c\/h6\u003e\n\u003cp\u003eOne year after their initial reference 43031, Vacheron Constantin introduced the reference 43032, distinguished by its skeletonised design. \u003cmeta charset=\"utf-8\"\u003e\u003cspan data-mce-fragment=\"1\"\u003eThe manufacture estimates that around 150 skeletonised watches were produced in platinum, with 130 of those bearing white subdials and 20 bearing blue subdials. A \u003c\/span\u003ehandful of pieces were also produced with diamonds on the bezel or dial.\u003c\/p\u003e\n\u003cp\u003eThe tradition of skeletonised watches dates back to 1760, when the French watchmaker André Charles Caron revealed the inner workings of a watch for customers to view by peeling back the watch dial. Since then, skeletonised watches have only begun to pick up in popularity over the last few years, demonstrating both the watchmaker’s skill and a growing public fascination with how watches work. \u003c\/p\u003e\n\u003ch6\u003eThe Design \u003c\/h6\u003e\n\u003cp\u003eWith its ornate, skeletonised design, this Vacheron Constantin reference 43032 is an intricately made piece that lays the secrets of watchmaking bare. From the dial to the open caseback, the watch creates space for the interplay of light and metal, providing a captivating visual depth. The exposed mechanics display an impressive level of hand-finishing, with vertical brushing, mirror polish and bevelling visible on most of the surfaces.

The watch famously crossed the English Channel in 1927, around the neck of English swimmer Mercedes Gleitze, surviving the 10-hour long swim undamaged. In 1931, Rolex patented the world's first self-winding mechanism with a perpetual rotor, today at the heart of every modern automatic watch.\u003c\/p\u003e\n\u003cp\u003eThe evolution of the Rolex Oyster inspired some of the most historically important wristwatches, surviving the harshest of conditions. From 35,000 ft. below the surface of the Pacific Ocean, to the summit of Mount Everest, without losing a beat. There aren’t many mechanical timepieces that have contributed more to the advancement of horological design, nor clearer defined Rolex’s reputation for excellence. Many have tried to replicate its success, but no manufacturer since, has consistently produced mechanical timepieces that endure everyday wear as well as a Rolex, owing much of their success to a unique market niche that the Oyster case helped define.\u003c\/p\u003e\n\u003ch6\u003eThe Oysterquartz\u003cbr\u003e\n\u003c\/h6\u003e\n\u003cp\u003eAs quartz technology gained prominence during the early '70s, Rolex began developing their own quartz movement, in an attempt to remain relevant and evolve with the times. \u003cmeta charset=\"utf-8\"\u003e\u003cspan data-mce-fragment=\"1\"\u003eBy 1977, they introduced the Oysterquartz, which housed their newly developed movement, within an angular case reminiscent of the Royal Oak and Nautilus, both of which has been introduced a few years prior.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003eHowever, the \u003cspan data-mce-fragment=\"1\"\u003ecase and bracelet were completed a few years prior to the battery-powered calibre 5035 being finished. As a result, Rolex chose to use a mechanical automatic calibre, whilst it finished its development. The result is the current reference 1530, which was in production between 1975 and 1977, whilst Rolex finalised research and development on its futuristic quartz movement. It is understood that around 1,500 pieces were produced during that brief two year timeframe.

The Quartz Crisis had decimated the watchmaking industry, with the number of watchmakers in Switzerland having dropped from 1,600 to 600. Against all odds, three watchmakers at Audemars Piguet decided to develop the world’s thinnest automatic perpetual calendar movement. The project was \u003ca title=\"Read our article on five movements that changed the world\" href=\"https:\/\/www.acollectedman.com\/blogs\/journal\/five-movements-changed-world-part-i\" target=\"_blank\"\u003ecarried out in secret\u003c\/a\u003e, with the manufacture’s upper management completely unaware of what was going on.

A risk taker who’d already released the Royal Oak a few years prior, Golay was confident that the manufacture could successfully commercialise the automatic perpetual calendar. When it was launched in 1978, the Quantième Perpetuel was the world’s thinnest automatic perpetual calendar. To put things in perspective, in 1984, only 1,066 perpetual calendars were produced in Switzerland.

The perpetual calendar indications are laid out in an intuitive manner. The date and day are shown at three and nine o’clock respectively, with the months displayed at twelve o’clock. A moonphase indication is placed at six o’clock, with graduations for the moon position just above. The “Audemars Piguet” font is flat and restrained, imbuing this piece with a certain vintage appeal. Later versions of the same reference are known to have a more contemporary font, giving them a distinctively more modern appearance.\u003c\/p\u003e\n\u003cp\u003eAs this is one of the earlier examples, the sub-dials are not recessed, enclosed between two thin black strokes, with the 6 o’clock sub-dial in a semi-circle.

It was first integrated into a wristwatch in 1925, by none other than Patek Philippe. For much of the 20th century, perpetual calendars remained scarce, on account of their niche appeal and the specialised skillset needed to design and assemble one. In the wake of the Quartz Crisis, these complicated pieces continued to be exceedingly rare, as their very purpose came under threat. Indeed, this seismic event had decimated the watchmaking industry, with the number of watchmakers in Switzerland having dropped from 1,600 to 600.\u003c\/p\u003e\n\u003cp class=\"p2\"\u003eHowever, against all odds, the perpetual calendar experienced a revival towards the end of the 20th century.

These were amongst the first perpetual calendars to be produced in a series.

They then reworked a perpetual calendar module from Dubois-Depraz, a famed module manufacturer, who has supplied Patek Philippe, Audemars Piguet and Vacheron Constantin, amongst others. The end result was the Caliber 1120 QP, which still remains in production to this day, albeit in an updated form.\u003cbr\u003e\u003c\/p\u003e\n\u003ch6 class=\"p2\"\u003eThe reference 43031\u003c\/h6\u003e\n\u003cp class=\"p2\"\u003eThe reference \u003cmeta charset=\"utf-8\"\u003e43031, which is understood to have been in production for around two decades, was the quintessential perpetual calendar model from Vacheron Constantin.

If we assume that annual production was always on the upper range, this would imply that Vacheron Constantin produced less than 2,300 of these perpetual calendars over 23 years.

It also further features English dial details, which paired with a platinum case, make the watch even more unusual.\u003c\/p\u003e\n\u003cp class=\"p2\"\u003eThis example features a subtly grained opaline dial, which is carried over to the  recessed sub-dials. This dial causes an interesting effect on the wrist, when the watch interacts with the light at different angles, and further imbuing this piece with a distinctive \u003ca title=\"Read our article on the Rise of Neo-Vintage Watches\" href=\"https:\/\/www.acollectedman.com\/blogs\/journal\/the-rise-of-neo-vintage-watches\" target=\"_blank\"\u003e\"neo-vintage\"\u003c\/a\u003e aesthetic.

Prior to this, perpetual calendars were extremely scarce.\u003c\/p\u003e\n\u003cp\u003eThe reference 3940 decided to abandon the aesthetics cemented by previous references. The dial layout was revamped, with the day and month aperture being replaced with three sub-dials. The sharp lines were substituted for a smoother, more modern design. Powered by a much thinner movement, it enabled an elegant, slim case that fits tightly to the wrist.\u003c\/p\u003e\n\u003ch6\u003eThe Elusive 3941\u003c\/h6\u003e\n\u003cp\u003eWhilst at first glance this may appear like a reference 3940, it is in fact the more elusive reference 3941. \u003cmeta charset=\"utf-8\"\u003e\u003cspan data-mce-fragment=\"1\"\u003eWhen the reference 3940 was first released in 1985, it featured a solid caseback, as \u003c\/span\u003ehad nearly every Patek Philippe watch produced before it. However, \u003cmeta charset=\"utf-8\"\u003e\u003cspan data-mce-fragment=\"1\"\u003ePatek Philippe received feedback from clients who wanted to admire the \u003c\/span\u003emicro-rotor movement through an open caseback. In response, the manufacture released an entirely new reference - the 3941 - which was produced alongside the 3940, but with a display caseback, instead of a closed one.\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cmeta charset=\"utf-8\"\u003e\u003cspan\u003eThese were amongst the first Patek Philippe pieces to be delivered with an open caseback, making this decision all the more remarkable. \u003cmeta charset=\"utf-8\"\u003eIn response to client demands, Patek Philippe began offering the reference 3940 with both solid and clear casebacks, and eventually discontinued the 3941 in 1990. Produced for a brief five year period, it is understood that the reference 3941 was available in yellow and white gold, with this being an example of the latter.\u003c\/span\u003e\u003c\/p\u003e\n\u003ch6\u003eA Classic Design\u003cbr\u003e\n\u003c\/h6\u003e\n\u003cp\u003eThe dial has three registers, with the various functions neatly laid out. The sub-dial at three o'clock shows the leap-year counter and the months, in English, in a slightly concave sub-register, giving depth to the lightly-brushed, opaline dial. In a similar fashion, the months and \u003cmeta charset=\"utf-8\"\u003e\u003cspan data-mce-fragment=\"1\"\u003e24-hour\u003c\/span\u003e indicators are placed at nine o'clock.\u003c\/p\u003e\n\u003cp\u003eThe silver moon and stars for the moon-phase are placed at six o'clock, with the days of the month around it. The 24-hour and weekday indicator at 9 o'clock mirror those at 3 o'clock, bringing a sense of balance and uniformity, to this relatively small but highly complicated dial. Despite the modest size, the 3941 remains legible and easy to use. The dauphine hands add a touch of sharpness to what only can be described as a wonderfully balanced design. \u003c\/p\u003e\n\u003cp\u003eEvidence suggests that the dials for reference 3941 were produced by Stern Frères, who provided many dials to Patek Philippe during this period. As seen from the bevelled edges that hold the day and month indicators at three and nine o’clock, the absence of the grave accent in “GENEVE” and the slightly larger Patek Philippe signature, this is a second series dial. From the cross divider that can be seen within the leap year indicator, it is evident that this falls within the late second series, made around 1989-1990, right before the reference was discontinued.\u003cbr\u003e\u003c\/p\u003e\n\u003ch6\u003eThe Movement\u003c\/h6\u003e\n\u003cp\u003eRepresenting the best of Swiss design, the movement itself is no less a technical feat. Through the sapphire caseback, the fantastic hand-finishing speaks for itself, and the wearer is able to admire the Genevan coat of arms and stripes, as well as the off-center, 22k gold micro-rotor.

It was first integrated into a wristwatch in 1925, by none other than Patek Philippe. For much of the 20th century, perpetual calendars remained scarce, on account of their niche appeal and the specialised skillset needed to design and assemble one. In the wake of the Quartz Crisis, these complicated pieces continued to be exceedingly rare, as their very purpose came under threat. Indeed, this seismic event had decimated the watchmaking industry, with the number of watchmakers in Switzerland having dropped from 1,600 to 600.\u003c\/p\u003e\n\u003cp\u003eIn 1985, against this challenging backdrop, IWC introduced the Da Vinci Perpetual Calendar reference 3750, combining a perpetual calendar and chronograph. This was a rather audacious move, carried out under created under the stewardship of Günter Blümlein as CEO of IWC, with the technical guidance of Kurt Klaus. For those not familiar with him, Blümlein was one of the main champions of mechanical watchmaking in the wake of the Quartz Crisis, having helped resuscitate the fortunes of Jaeger-LeCoultre, IWC and A. Lange \u0026amp; Söhne.\u003c\/p\u003e\n\u003cp\u003eKurt Klaus based the movement on a heavily modified Valijoux 7750, developing an in-house perpetual calendar module to sit on top of It, resulting in the calibre IWC 79261. According to the brand, it was during long walks with his dogs that Klaus mentally projected a new kind of perpetual calendar module, that would only include 81 individual parts and function autonomously, with virtually no correction, until 2499. It was also designed with ease of use in mind, such that all the functions - date, day, month, moon phase and year - are synchronised and can advanced together via the crown. \u003c\/p\u003e\n\u003ch6\u003eA Bold Design\u003c\/h6\u003e\n\u003cp\u003eThis version of the Da Vinci Perpetual Calendar Chronograph combines a black dial with a striking rose gold case and bracelet. The perpetual calendar functions are laid out in a clear and intuitive manner. The sub-dials are in rose gold, with a subtle pattern in radiating concentric circles. The moonphase is at 12 o’clock, while the day, month, and date sub-dials are at 9, 6, and 3 o’clock respectively. Additionally, the sub-dials also double up by indicating the chronograph functions. The subdial displays are in German - one of the four languages that this piece was made available in - with a counter indicating the year is placed at the lower left side of the dial.\u003c\/p\u003e\n\u003cp\u003eMeanwhile, the hour and minute hands are in a matching rose-gold metal as the case, and are lume-filled, as are the index markers, allowing for legibility in low-light conditions. The watch also features a “beads of rice” bracelet, which is original to the watch, a design choice that highlights the neo-vintage appearance of the watch. The case is classic, with a twist, being round in profile, with hooded lugs which elegantly blend into the bracelet. Overall, the combination or rose, black and the occasional red detail makes this pieces distinctive and captivating on the wrist.\u003c\/p\u003e\n\u003ch6\u003eThe Movement\u003c\/h6\u003e\n\u003cp\u003eThis IWC Da Vinci Ref. 9252 is powered by the self-winding calibre 79261, a self-winding chronograph movement that is fitted with a perpetual calendar module.

The Jürgensen manufacture was started by Urban Jürgensen, along with his father Jürgen Jürgensen, and has long been credited with introducing the watch industry to Denmark. Shortly after the birth of his son in 1776, Jürgen Jürgensen moved to Le Locle in Switzerland to work with Jacques-Frédéric Houriet, laying the foundations for a Danish-Swiss connection which still exists over 240 years later.\u003c\/p\u003e\n\u003cp\u003eThe modern Jürgensen brand was acquired by Peter Baumberger in 1979, with master watchmaker Derek Pratt at the helm. The pair then set about carrying forward a legacy of elegant and complicated timepieces, whilst pioneering concepts of performance, stability and movement aesthetics. Despite being amongst the most accomplished independant watchmakers of the last century, Pratt remains largely unrecognised within the field.\u003c\/p\u003e\n\u003cp\u003eHe was a long-standing friend of George Daniels, and it is believed that the pair used to have lengthy telephone discussions every Sunday morning, sharing ideas back and forth between themselves, whilst also working closely together on more than one occasion. The Reference 3 epitomises this period of Urban Jürgensen’s history in the best way, bringing together an impressive perpetual calendar movement, based on a highly-refined Frédéric Piguet calibre, with balanced aesthetics and a hand-finished dial. The perpetual calendar module is said to have been of the watchmaker's own creation, whilst many of the dials throughout this period were engine turned by Pratt himself.\u003c\/p\u003e\n\u003ch6\u003eA Balanced Design\u003c\/h6\u003e\n\u003cp\u003eThe Urban Jürgensen Perpetual Calendar Reference 3 is cased in platinum, using the brand’s distinctive teardrop lugs and convex bezel. Forged separately from the case, the teardrop lugs are carefully heat-treated, hand-polished and individually soldered into place using mid-century horological methods, with no visible soldering line.\u003c\/p\u003e\n\u003cp\u003eThe hand-finished, engine-turned guilloché dial requires up to 700 operations and two full days of hand craftsmanship to complete. Manufactured from one piece of solid silver, the varying guilloché patterns create a varied texture, which creates a beautiful interplay with the light. A cartouche below the moonphase sub-dial twelve o'clock references “Urban Jürgensen Copenhagen”, with the piece’s unique number placed within the moonphase. The day and date apertures are placed close to the 9 and 3 o’clock index markers respectively.\u003c\/p\u003e\n\u003cp\u003eThe deep blue background of the moonphase set with a yellow moon and stars provides a wonderful contrast with the monochromatic dial and naturally draws the eye towards it. The polished date chapter is set diametrically below the moonphase, while the dates themselves centre around a slender gold indicator, with an elegant counter-balance at one end; a subtle mirroring of the crescent shaped moonphase aperture.\u003c\/p\u003e\n\u003cp\u003eThe index markers are printed in black on an ivory-coloured chapter ring surrounding the centre of the dial, and there is a dotted minute track running along the outermost section. The handmade, solid gold Observatoire-style hands are turned on a precision lathe, and mirror-polished, with the arms of the hands carefully riveted in place, creating a unique effect reminiscent of early 18th and 19th-century marine chronometers made by Urban Jürgensen.\u003c\/p\u003e\n\u003ch6\u003eThe Movement\u003c\/h6\u003e\n\u003cp\u003eThe Urban Jürgensen Perpetual Calendar Reference 3 uses a high-quality Frederic Piguet 71 ébauche, an ultra-slim, self-winding calibre that has an open barrel.

Alongside similar pieces from Audemars Piguet and Patek Philippe, it is one of the few ultra-thin, automatic perpetual calendars introduced during this period.\u003c\/p\u003e\n\u003c!-- SECTION BREAK --\u003e\n\u003ch6\u003eReviving the Perpetual Calendar\u003c\/h6\u003e\n\u003cp\u003eThe perpetual calendar has always been one of the most classic complications in horology. It was first integrated into a wristwatch in 1925, by none other than Patek Philippe. For much of the 20th century, perpetual calendars remained scarce, on account of their niche appeal and the specialised skillset needed to design and assemble one. In the wake of the Quartz Crisis, these complicated pieces continued to be exceedingly rare, as their very purpose came under threat. Indeed, this seismic event had decimated the watchmaking industry, with the number of watchmakers in Switzerland having dropped from 1,600 to 600.\u003c\/p\u003e\n\u003cp\u003eHowever, against all odds, the perpetual calendar experienced a revival towards the end of the 20th century. Within the span of seven years, between 1978 and 1985, Audemars Piguet, Vacheron Constantin and Patek Philippe all introduced their own ultra-thin, automatic perpetual calendars. These were amongst the first perpetual calendars to be produced in a series. This marked a fundamental departure with the past, when each of the manufactures from “Holy Trinity” of watchmaking would only have produced a few dozen of these pieces a year, at the very most. This signified a renewed faith in the future of complicated horology.\u003c\/p\u003e\n\u003cp\u003eWhilst Audemars Piguet were the first out of the gate in 1978, it is believed that Vacheron Constantin unveiled their automatic, ultra-thin perpetual calendar wristwatch in 1983. Rather frustratingly for Patek Philippe, this was two years before they came out with their own reference 3940. As a staring point, Vacheron Constantin used the mythical Jaeger-LeCoultre 920, which was the thinnest automatic movement in the world when it came out in 1967. They then reworked a perpetual calendar module from Dubois-Depraz, a famed module manufacturer, who has supplied Patek Philippe, Audemars Piguet and Vacheron Constantin, amongst others. The end result was the Caliber 1120 QP, which still remains in production to this day, albeit in an updated form.\u003c\/p\u003e\n\u003cp\u003eThe reference 43031, which is understood to have been in production for around two decades, was the quintessential perpetual calendar model from Vacheron Constantin. It was produced in a range of different configurations, with different metals, dials and bracelet options available. A striking skeletonised version was also produced, under the reference 43032. Nowadays, these pieces stand out as a significant step in helping Vacheron Constantin weather the aftermath of the Quartz Crisis, and help revive the interest in complicated watchmaking. Around 2002, the model was discontinued, leaving way for the manufacture's more contemporary pieces.\u003c\/p\u003e\n\u003ch6\u003eThe Reference 43031\u003c\/h6\u003e\n\u003cp\u003eThe reference 43031, which is understood to have been in production for around two decades, was the quintessential perpetual calendar model from Vacheron Constantin. It was produced in a range of different configurations, with different metals, dials and bracelet options available, including a striking skeletonised version under the reference 43032. Nowadays, these pieces stand out as a significant step in helping Vacheron Constantin weather the aftermath of the Quartz Crisis, and help revive the interest in complicated watchmaking. Around 2006, the model was discontinued, leaving way for the manufacture's more contemporary pieces.\u003c\/p\u003e\n\u003cp\u003eAccording to the manufacture, production figures varied quite significantly throughout between 1983 and 2006, from around 20 to 100 pieces made per year. If we assume that annual production was always on the upper range, this would imply that Vacheron Constantin produced less than 2,300 of these perpetual calendars over 23 years. Rather surprisingly, this is almost three times less than Audemars Piguet or Patek Philippe ever produced of their own equivalent references.\u003c\/p\u003e\n\u003ch6\u003eThe Design\u003c\/h6\u003e\n\u003cp\u003eThis Vacheron Constantin ref. 43031 features a classic, pared back design. The perpetual calendar indications are laid out in an intuitive manner. The date and day are shown at three and nine o’clock respectively, with the months and leap year displayed at twelve o’clock. A moonphase indication is placed at six o’clock, with graduations for the moon position just above. The “Vacheron Constantin” signature sits below the moonphase. Rather interestingly, the different dial indications are in French, pointing to the manufacture's Swiss origins. This particular piece is part of the second series, as can be seen with the inclusion of the Maltese cross above the signature.\u003c\/p\u003e\n\u003cp\u003eThe sub-dials of the piece are slightly recessed and feature a more restrained, circular finish. This creates some interesting effects when the watch interacts with the light at different angles, whilst on the wrist. The hands for the sub-dials are made out of blued steel, which adds an appealing level of contrast to the overall design. Rather interestingly, the moonphase is made out of lapis lazuli, a deep blue metamorphic rock, which has been used for jewellery and decorative objects since antiquity because of its intense colour.\u003c\/p\u003e\n\u003cp\u003eThe yellow gold case features a stepped bezel and straight lugs, reminiscent of those found on some vintage pieces. Four pushers on the corner of the case allow for the various perpetual calendar indications to be set. At 36mm in diameter and less than 8mm thick, this ref. 43031 sits comfortably on the wrist. It also features a closed caseback, with clearly defined engravings.\u003c\/p\u003e\n\u003ch6\u003eThe Movement\u003c\/h6\u003e\n\u003cp\u003eThis Vacheron Constantin ref. 43031 is powered by the 1120\/2, derived from Jaeger-LeCoultre’s mythical ultra-thin JLC 920 movement. The caliber 920 was an initial project of Jaeger LeCoultre in 1967, funded and contributed by Audemars Piguet, and famous for its adoption by Audemars Piguet, Patek Philippe and Vacheron Constantin.\u003c\/p\u003e\n\u003cp\u003eThe ultra-thin automatic 1120\/2 calibre features 36 working jewels, and four ruby wheels to support the full-diameter rotor, which runs on a beryllium rail for stability. Vacheron Constantin also replaced the free-sprung Gyromax balance from the original Jaeger-LeCoultre movement with an index regulator.\u003c\/p\u003e\n\u003cp\u003eThe rotor is decorated with Geneva stripes and edged with 21-carat gold, to increase the oscillating mass. This movement carries the Geneva Seal, which is unique in its accreditation as it focuses on the art of decorating a movement with finesse and skill, in the style of Genevan watchmaking.\u003c\/p\u003e\n\u003ch6\u003eThe Set\u003c\/h6\u003e\n\u003cp\u003eThis Vacheron Constantin ref. 43031 comes with its leather folio, Certificate of Origin and Warranty (undated, stamped by the retailer in Lisbon, Portugal), manuals and Vacheron Constantin servicing paperwork from 2001.

Combining a platinum case and a skeletonised version of the ultra-thin, automatic 1120QP movement, it manages to thoughtfully balance tradition and modernity.\u003c\/p\u003e\n\u003c!-- SECTION BREAK --\u003e\n\u003ch6\u003eReviving the Perpetual Calendar\u003c\/h6\u003e\n\u003cp\u003eThe perpetual calendar has always been one of the most classic complications in horology. It was first integrated into a wristwatch in 1925, by none other than Patek Philippe. For much of the 20th century, perpetual calendars remained scarce, on account of their niche appeal and the specialised skillset needed to design and assemble one. In the wake of the Quartz Crisis, these complicated pieces continued to be exceedingly rare, as their very purpose came under threat. Indeed, this seismic event had decimated the watchmaking industry, with the number of watchmakers in Switzerland having dropped from 1,600 to 600.\u003c\/p\u003e\n\u003cp\u003eHowever, against all odds, the perpetual calendar experienced a revival towards the end of the 20th century. Within the span of seven years, between 1978 and 1985, Audemars Piguet, Vacheron Constantin and Patek Philippe all introduced their own ultra-thin, automatic perpetual calendars. These were amongst the first perpetual calendars to be produced in a series. This marked a fundamental departure with the past, when each of the manufactures from “Holy Trinity” of watchmaking would only have produced a few dozen of these pieces a year, at the very most. This signified a renewed faith in the future of complicated horology.\u003c\/p\u003e\n\u003cp\u003eWhilst Audemars Piguet were the first out of the gate in 1978, it is believed that Vacheron Constantin unveiled their automatic, ultra-thin perpetual calendar wristwatch in 1983. Rather frustratingly for Patek Philippe, this was two years before they came out with their own reference 3940. As a starting point, Vacheron Constantin used the mythical Jaeger-LeCoultre 920, which was the thinnest automatic movement in the world when it came out in 1967. They then reworked a perpetual calendar module from Dubois-Depraz, a famed module manufacturer, who has supplied Patek Philippe, Audemars Piguet and Vacheron Constantin, amongst others. The result was the Caliber 1120 QP, which remains in production to this day, albeit in an updated form.\u003c\/p\u003e\n\u003ch6\u003eA Skeletonised Approach\u003c\/h6\u003e\n\u003cp\u003eOne year after their initial reference 43031, Vacheron Constantin introduced the reference 43032, distinguished by its skeletonised design. The manufacture estimates that around 150 skeletonised watches were produced in platinum, with 130 of those bearing white subdials and 20 bearing blue subdials. A handful of pieces were also produced with diamonds on the bezel or dial.\u003c\/p\u003e\n\u003cp\u003eThe tradition of skeletonised watches dates back to 1760, when the French watchmaker André Charles Caron revealed the inner workings of a watch for customers to view by peeling back the watch dial. Since then, skeletonised watches have only begun to pick up in popularity over the last few years, demonstrating both the watchmaker’s skill and a growing public fascination with how watches work.\u003c\/p\u003e\n\u003ch6\u003eThe Design\u003c\/h6\u003e\n\u003cp\u003eWith its ornate, skeletonised design, this Vacheron Constantin reference 43032 is an intricately made piece that lays the secrets of watchmaking bare. From the dial to the open caseback, the watch creates space for the interplay of light and metal, providing a captivating visual depth. The exposed mechanics display an impressive level of hand-finishing, with vertical brushing, mirror polish and bevelling visible on most of the surfaces. Many of the components, both at the front and back, feature a traditional hand-engraving in a floral pattern, which is subtle and refined.\u003c\/p\u003e\n\u003cp\u003eThere are four sub-dials present, as is traditional with the style of perpetual calendars, noting day, month, and date, as well as moonphase. For greater legibility, the subdials are rendered in plain white. The moonphase that can be found on this Ref. 43032 is made from lapis lazuli, a deep blue metamorphic rock that adds a small spark of colour to an otherwise pared-back colour palette.\u003c\/p\u003e\n\u003cp\u003eThe feuille-style hands are rendered in a similar shade as the watch case, their shape allowing for a slight contrast in depth compared to the rest of the watch. The reference 43032 makes use of a 48-month sub-dial, allowing the wearer to track what stage of the four-year cycle they’re in, and allows for more precision in tracking the changing years over a longer period of time.\u003c\/p\u003e\n\u003ch6\u003eThe Movement\u003c\/h6\u003e\n\u003cp\u003eThis Vacheron Constantin 43032 is powered by the 1120QP, an illustrious movement introduced in 1983 that built on the high-quality JLC 920 ébauche. With the help of famed Swiss complications specialist, Dubois Dépraz, the perpetual calendar module remains in use today, with the most recent perpetual calendars produced by the brand still running on this movement.\u003c\/p\u003e\n\u003cp\u003eThe 1120QP is an ultra-thin, self-winding movement that is fitted with an open-worked oscillating weight that bears the signature Maltese Cross.

The complication has become a signature of Dubuis’ early work, and bears many of the hallmarks of his time at Patek Philippe.\u003c\/p\u003e\n\u003c!-- SECTION BREAK --\u003e\n\u003cp\u003eThe history of Roger Dubuis is rich and complex, as Dubuis started his career in the 1950s working for Longines, before moving on to Patek Philippe’s complications department, before breaking away to start his own workshop in the ‘80s. Later on, in 1995, Dubuis would launch his eponymous brand with the help of businessman Carlos Dias.\u003c\/p\u003e\n\u003cp\u003eAccording to Dubuis himself, he began work on this complication in the late 1980s – a perpetual calendar module with retrograde displays. For several years, Roger Dubuis worked on the complication with Jean-Marc Wiederrecht, founder of respective complications specialist Agenhor. This was first developed for Harry Winston, who announced their own version of the Bi-Retrograde Perpetual Calendar at Baselworld, in 1989. It was the first double retrograde perpetual calendar, and Roger Dubuis later made the same perpetual module the signature complication of his brand.\u003c\/p\u003e\n\u003cp\u003eIn addition to the highly stylised dial layout, the piece is further distinguished by the days, which are rendered in French – making this an especially rare variation on Dubuis’ signature complication. Two references to Dubuis’ past work with Patek Philippe will not escape the eye of the discerning collector. The first is the flared finish of the pushers that invoke the Patek Philippe reference 1463 \"Tasti Tondi\", while the second is the use of the Lemania 2310, a calibre shared by Dubuis’ movement, the calibre RD 5632, and the Patek Philippe reference 3970, a perpetual calendar piece that also integrates a chronograph function.\u003c\/p\u003e\n\u003cp\u003eIf sold within the United Kingdom, this Roger Dubuis Bi-Retrograde Perpetual Calendar Chronograph will be subject to 20% VAT.\u003c\/p\u003e\n\u003c!-- SECTION BREAK --\u003e\n\u003ch6\u003e\u003cstrong\u003eCloser look \u003c\/strong\u003e\u003c\/h6\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr style=\"height: 20px;\" data-mce-style=\"height: 20px;\"\u003e\n\u003ctd style=\"height: 20px;\" width=\"63\" data-mce-style=\"height: 20px;\"\u003eBrand:\u003c\/td\u003e\n\u003ctd style=\"height: 20px;\" width=\"213\" data-mce-style=\"height: 20px;\"\u003eRoger Dubuis\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 20px;\" data-mce-style=\"height: 20px;\"\u003e\n\u003ctd style=\"height: 20px;\" width=\"63\" data-mce-style=\"height: 20px;\"\u003eModel:\u003c\/td\u003e\n\u003ctd style=\"height: 20px;\" width=\"213\" data-mce-style=\"height: 20px;\"\u003eBi-Retrograde Perpetual Calendar Chronograph\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 20px;\" data-mce-style=\"height: 20px;\"\u003e\n\u003ctd style=\"height: 20px;\" width=\"63\" data-mce-style=\"height: 20px;\"\u003eMovement:\u003c\/td\u003e\n\u003ctd style=\"height: 20px;\" width=\"213\" data-mce-style=\"height: 20px;\"\u003eRD5632\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 20px;\" data-mce-style=\"height: 20px;\"\u003e\n\u003ctd style=\"height: 20px;\" width=\"63\" data-mce-style=\"height: 20px;\"\u003eFunctions:\u003c\/td\u003e\n\u003ctd style=\"height: 20px;\" width=\"213\" data-mce-style=\"height: 20px;\"\u003ePerpetual calendar, chronograph\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 20px;\" data-mce-style=\"height: 20px;\"\u003e\n\u003ctd style=\"height: 20px;\" width=\"63\" data-mce-style=\"height: 20px;\"\u003eCase:\u003c\/td\u003e\n\u003ctd style=\"height: 20px;\" width=\"213\" data-mce-style=\"height: 20px;\"\u003eWhite gold\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 20px;\" data-mce-style=\"height: 20px;\"\u003e\n\u003ctd style=\"height: 20px;\" width=\"63\" data-mce-style=\"height: 20px;\"\u003eCase diameter:\u003c\/td\u003e\n\u003ctd style=\"height: 20px;\" width=\"213\" data-mce-style=\"height: 20px;\"\u003e37mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 20px;\" data-mce-style=\"height: 20px;\"\u003e\n\u003ctd style=\"height: 20px;\" width=\"63\" data-mce-style=\"height: 20px;\"\u003eCrystal:\u003c\/td\u003e\n\u003ctd style=\"height: 20px;\" width=\"213\" data-mce-style=\"height: 20px;\"\u003eSapphire\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 20px;\" data-mce-style=\"height: 20px;\"\u003e\n\u003ctd style=\"height: 20px;\" width=\"63\" data-mce-style=\"height: 20px;\"\u003eStrap:\u003c\/td\u003e\n\u003ctd style=\"height: 20px;\" width=\"213\" data-mce-style=\"height: 20px;\"\u003eGrey leather strap, white gold Roger Dubuis deployante buckle\u003cbr\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 20px;\" data-mce-style=\"height: 20px;\"\u003e\n\u003ctd style=\"height: 20px;\" width=\"63\" data-mce-style=\"height: 20px;\"\u003eLug width:\u003c\/td\u003e\n\u003ctd style=\"height: 20px;\" width=\"213\" data-mce-style=\"height: 20px;\"\u003e18mm\u003cbr\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"height: 20px;\" data-mce-style=\"height: 20px;\"\u003e\n\u003ctd style=\"height: 20.5417px;\" width=\"63\" data-mce-style=\"height: 20.5417px;\"\u003eYear:\u003c\/td\u003e\n\u003ctd style=\"height: 20.5417px;\" width=\"213\" data-mce-style=\"height: 20.5417px;\"\u003ec. 2000\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003eThis Roger Dubuis Bi-Retrograde Perpetual Calendar Chronograph is in very good condition overall, with a few superficial marks consistent with light wear over time.

Of course, collectors of vintage pieces will be familiar with the unique appeal of a “tone on tone” watch, where the dial and case subtly complement one another, a feature which certainly makes this piece stand out. These champagne toned dials are also particularly rare within the reference 43031, as is the case with other perpetual calendars from the period, such as those by Audemars Piguet and Patek Philippe.\u003c\/p\u003e\n\u003cp\u003eFurther to this, the watch is also fitted with an intricate integrated bracelet that is directly attached to the case itself, giving the watch a simple silhouette.

They then reworked a perpetual calendar module from Dubois-Depraz, a famed module manufacturer who has supplied Patek Philippe, Audemars Piguet and Vacheron Constantin, among others.

The design focuses on balance – with sub-dials placed at 3, 6, and 9 o’clock respectively – and more crucially, in a way that does not make the dial seem over-complicated, despite the highly complicated nature of the watch itself.\u003c\/p\u003e\n\u003cp\u003eThis example is even more noteworthy for being made from rose gold, which is rarely used in the reference 3940. Whilst yellow gold, white gold and platinum is found across all three series of the reference, Patek Philippe only introduced rose gold from the late second series onwards and carried it into the third. Whilst white metals remain the rarest, rose gold remains interesting nonetheless, and presents an appealing alternative for a collector who appreciates the warmth of yellow gold, but is seeking something more unusual.\u003c\/p\u003e\n\u003cp\u003eSeveral factors distinguish this as a later second series piece rather than a first or third series, such as the lack of a grave accent on “Geneve”, and the fact that the “Swiss made” sign is printed in a way that is slightly misaligned with the rest of the minute track. Further to this, the piece features a cross divider on the month and leap year sub-dial, which was a feature introduced after the first series.

It marks an intriguing part of watchmaking history, both in the history of the battle for the thinnest watch, as well as with regards to the brand’s incredible recovery during the Quartz Crisis.\u003c\/p\u003e\n\u003c!-- SECTION BREAK --\u003e\n\u003cp\u003eThis is a rare example which is encased in platinum, of which a smaller number were made compared to the pieces that can be found in yellow gold. A descendant of the IWC Da Vinci, a perpetual calendar watch which introduced the ground-breaking calibre IWC 79261 created by Kurt Klaus, this IWC Romana Perpetual Calendar 2050 is a piece that pairs it back a step by creating a thinner version of the movement.\u003c\/p\u003e\n\u003cp\u003eThe original movement found in the IWC Da Vinci was a heavily modified Valjoux 7750, for which Kurt Klaus developed an in-house perpetual calendar module to sit on top of it, resulting in the calibre IWC 79261. According to the brand, it was during long walks with his dogs that Klaus mentally projected a new kind of perpetual calendar module that would only include 81 individual parts and function autonomously, with virtually no correction, until 2499. It was also designed with ease of use in mind, with a “quick-set” function that would allow each of the indications – date, day, month, moon phase and year – to be synchronised and advanced together via the crown.\u003c\/p\u003e\n\u003cp\u003eThe design of the piece is remarkably classic, with the four sub-dials set around the face of the watch in a clear, intuitive manner, and the days, months, and dates all written in serif font. Overall, the dial has a muted grey shade which complements the platinum case. In order to counteract the already rather busy look of the dial, the Roman numerals indicating the hours are placed unusually close to the edge of the case, giving a greater sense of space and balance. A closer look at the moonphase reveals a shimmering effect not unlike the kind produced by the aventurine stone, and the blued hands are also a point of interest: they are feuille-style for the hours and minutes, and sword-shaped on the sub-dials.\u003c\/p\u003e\n\u003cp\u003eThe quick-set function mentioned above has been used in the calibre 84961, although the piece must be manually wound.

The reference 5548 was the first reference of this newly released perpetual calendar, birthing a category of watches which has taken on many different forms. Sources note that total production was documented at 2,183 pieces, and of those, yellow-gold cases were the most widely produced at 2,066 units.\u003c\/p\u003e\n\u003cp\u003eHowever, this early example stands out for its rare dial configuration. Whilst most examples of the reference 5548 feature applied indices, this example features printed Roman numerals, which imbue this piece with an even more classic aesthetic. Though the change is subtle, it does give the watch a different aesthetic and persona. This early dial also features other traits which single it out as being part of the brand’s early production, such as the small “Audemars Piguet” signature of the “Swiss” only signature at the bottom.\u003c\/p\u003e\n\u003cp\u003eThe lines of the Quantième Perpétuel were penned by Jacqueline Dimier, who is considered by some as the protégé of the legendary \u003ca href=\"https:\/\/www.acollectedman.com\/blogs\/journal\/interview-evelyne-genta\" title=\"Gérald Genta\" target=\"_blank\"\u003eGérald Genta\u003c\/a\u003e. The perpetual calendar indications are laid out in an intuitive manner. The date and day are shown at 3 and 9 o’clock respectively, with the months displayed at 12 o’clock. A moonphase indication is placed at 6 o’clock, with graduations for the moon position just above.\u003c\/p\u003e\n\u003cp\u003eAs this is one of the earlier examples, the sub-dials are not recessed, enclosed between two thin black strokes, with the 6 o’clock sub-dial in a semicircle. Meanwhile, the gold stick hands provide excellent legibility against the white background. The case is a double-stepped bezel, with three pushers only very visible when the watch is turned over. At 36mm in diameter and less than 8mm thick, this 5548BA sits comfortably on the wrist. On the reverse of the yellow-gold case, the watch features finely engraved markings, confirming the watch’s individual case number, which is below 800.\u003c\/p\u003e\n\u003cp\u003eThe reference 5548 is the first watch to be fitted with the ultra-thin, automatic calibre 2120\/2800, derived from Jaeger-LeCoultre’s celebrated \u003ca href=\"https:\/\/www.acollectedman.com\/blogs\/journal\/five-movements-changed-world-part-i\" title=\"Ultra-thin JLC 920 movement\" target=\"_blank\"\u003eultra-thin JLC 920 movement\u003c\/a\u003e.

The aesthetic of the collection was based on a unique, historic tank design from Audemars Piguet from the mid-1920s. The overall collection is distinguished by its elegantly curved rectangular cases, subtly reminiscent of understated Art Deco sophistication. Symmetrical, geometrical, and elongated, this specific piece looks back to early 20th-century design.\u003c\/p\u003e\n\u003cp\u003eThe dial integrates the traditional layout for a perpetual calendar, though subtly reworked for its rectangular shape. The sub-dial at 3 o’clock shows the date, in a noticeably recessed sub-register, giving depth to the otherwise smooth silver dial. In a similar fashion, the days of the month are placed at 9 o’clock, with the months of the year at 12.\u003c\/p\u003e\n\u003cp\u003eThe moonphase is placed at 6 o’clock. The depth of the sub-dials, and their light circular finish, gives the watch an even more distinctive appearance on the wrist. The silvered dial is further accented with painted Breguet numerals, a feature occasionally found, and often desired, in perpetual calendars from the past. These correspond harmoniously with Audemars Piguet’s black leaf hands.\u003c\/p\u003e\n\u003cp\u003eThis Quantième Perpetuel 25682BA is powered by the manual-wind calibre 2003. The base movement, developed in conjunction with ébauche maker Jaeger-LeCoultre, was first developed in 1946, remaining in production for half a century. On top of it, Audemars Piguet added their 2805 QP perpetual calendar module, giving the movement a total thickness of only 3.19mm. The movement is beautifully finished, with exquisite chamfering on all angles, polishing, and decoration, in the form of Geneva striping.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eIf sold within the United Kingdom, this Audemars Piguet Edward Piguet Quantième Perpetuel 25682 will be subject to 20% VAT.\u003c\/em\u003e\u003c\/p\u003e\n\u003c!-- SECTION BREAK --\u003e\n\u003ch6\u003e\u003cstrong\u003eCloser look \u003c\/strong\u003e\u003c\/h6\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eBrand:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003eAudemars Piguet\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eModel:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003eEdward Piguet Quantième Perpetuel 25682\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eMovement:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003eManual-winding\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eFunctions:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003ePerpetual calendar functions (month, day, date, moonphase), hours, minutes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eCase material:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003eRose gold\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eCase diameter:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003e45mm x 27mm x 8.5mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eCrystal:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003eSapphire front and back\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eStrap:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003eACM's strap - \u003ca title=\"A Collected Man's Watch Strap\" href=\"https:\/\/www.acollectedman.com\/collections\/straps\/products\/geneva-brown-buffalo-watch-strap#\" target=\"_blank\"\u003e\u003cspan style=\"text-decoration: underline;\"\u003eBrown nubuck calf\u003c\/span\u003e\u003c\/a\u003e, black alligator strap, Audemars Piguet rose gold buckle\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eLug width:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003e22x16mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eYear:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003ec. 2000\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eBox \u0026amp; papers:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003e -\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003eThis Audemars Piguet Edward Piguet Quantieme Perpetuel is in excellent overall condition with consistent superficial marks throughout the case and lugs, relative with regular wear over time.

Just a few years later, the manufacture chose to combine this innovative movement with their iconic Royal Oak cases. In 1983, they released the reference 5554, which is also designated as the reference 25554. This reference 25654 can be considered a “first series” example, as it was introduced in a subsequent iteration of the concept, featuring the same pared back aesthetic as the original design.

The sub-dials are slightly recessed, giving the dial greater depth and texture. Additionally, the dial displays the \"Audemars Piguet\" signature in small lettering, which is only found on the earlier examples of the reference 25654, before the brand adopted its modern signature style.\u003c\/p\u003e\n\u003cp\u003eMeanwhile, the polished screws, bezel and case edges provide a distinct contrast with the brushed surface of the case and bracelet. The watch possesses its original unsigned crown, white gold clasp and clasp cover with the correct \"AP\" signature. Furthermore, this Quantième Perpetuel Automatique is powered by the Caliber 2120\/2800, derived from Jaeger-LeCoultre’s legendary ultra-thin JLC 920 movement. The Caliber 2120 was an initial project of Jaeger LeCoultre in 1967, funded and contributed by Audemars Piguet, and famous for its adoption by Audemars Piguet, Patek Philippe and Vacheron Constantin.\u003c\/p\u003e\n\u003c!-- SECTION BREAK --\u003e\n\u003ch6\u003e\u003cstrong\u003eCloser look \u003c\/strong\u003e\u003c\/h6\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eBrand:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003eAudemars Piguet\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eModel:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003eRoyal Oak ref. 25654BA Quantieme Perpetual\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eMovement:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003eAutomatic AP calibre 2120\/2800\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eFunctions:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003ePerpetual calendar, month, date, day, moonphase, hours, minutes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eCase material:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003eYellow gold\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eCase diameter:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003e39mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eCrystal:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003eSapphire front\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eStrap:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003eYellow gold integrated bracelet 17 links (2 removable), for approximately 6 ½ inch wrist\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eLug width:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003eN\/a\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eYear:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003ec.1990\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eBox \u0026amp; papers:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003e -\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003cp\u003eThis Audemars Piguet Quantième Perpétuel Royal Oak is in good condition overall.

The hands for the sub-dials are blackened, which adds an appealing level of contrast to the overall design.

It shares design traits with early second series examples, produced between 1987 and 1989, following the first series with sunken sub-dials. Examples of the reference 3940 with this type of dial are typically only found in pieces made fairly early on in production, and only a small number have appeared publicly.\u003c\/p\u003e\n\u003cp\u003eMost notably, the earliest Beyer-signed 3940s with first series dials were equipped with this rare doré tone. The word “doré” itself references “a gold or gold-like substance”, which is a fitting description for this 3940, with its alluring, bright texture. The appeal extends to a number of historically important Patek Philippe watches, with examples of the references 2499, 3448, and 3971 having all been discovered with similar doré dials. As a testament to their desirability, Philippe Stern, the then-executive of Patek Philippe, was once seen wearing a 3940 with a similar golden shade.\u003c\/p\u003e\n\u003cp\u003eAs is often the case with early examples, it features a solid yellow gold caseback, hiding away the true beauty of the movement in an elegant and traditional fashion. Outside of the first series, this example is one of the earliest known with a doré dial to have a closed caseback. Created towards the turn of the century, this watch is an excellent example of the neo-vintage movement, marking an exciting period of rebirth for the watch industry. At 36mm, the watch wears comfortably on the wrist while the size is also being reminiscent of vintage watches, further adding to its charm.\u003c\/p\u003e\n\u003ch6\u003eProvenance\u003c\/h6\u003e\n\u003cp\u003eThe watch was purchased by the original owner from an authorised retailer in the Scottish city of Glasgow.

The exposed mechanics display an impressive level of hand-finishing, with vertical brushing, mirror polish and bevelling visible on most of the surfaces.

For greater legibility, this seldom-seen variant with blue subdials features a plain white font for the indications.

Meanwhile, the moonphase found on this reference 43032 is made from lapis lazuli, a deep blue metamorphic rock that adds a subtle contrast against the white subdials.

The series was discontinued in 2012 after just 15 years of production, and was followed by the reference 5204.

The dial takes inspiration from the reference 1518, borrowing the same style of Arabic numerals and combining them with a classic tachymeter scale.

According to then-president Philippe Stern, as quoted in Revolution Magazine, it wasn't easy to get this right. \"The problem was that the Lemania 2310 or CH 27, was never intended to be a split seconds chronograph. We had two major challenges. The first was the pinion that all the hands – hours, minutes, chronograph seconds and split seconds – had to be made even longer and we were really stretching the limits of what was possible. Even the slightest mistake it was easy to bend this pinion. And second thing was that the CH 27 would experience rattrapante drag each time the split seconds function was activated.\" This problem was eventually solved by including an isolator, which lifts the rattrapante roller from the heart cam and only connects the two once the split-seconds function is released.\u003c\/p\u003e\n\u003cp\u003e \u003cbr\u003e\u003c\/p\u003e\n\u003c!-- SECTION BREAK --\u003e\n\u003ch6\u003e\u003cstrong\u003eCloser look \u003c\/strong\u003e\u003c\/h6\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eBrand:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003ePatek Philippe\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eModel:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003eSplit Seconds Chronograph ref. \u003cmeta charset=\"utf-8\"\u003e \u003cspan data-mce-fragment=\"1\"\u003e\u003cspan dir=\"ltr\" class=\"ui-provider wd b c d e f g h i j k l m n o p q r s t u v w x y z ab ac ae af ag ah ai aj ak\" data-mce-fragment=\"1\"\u003e5004G-013\u003c\/span\u003e\u003c\/span\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eMovement:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003emanual-winding calibre CH2770 Q\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eFunctions:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003eperpetual calendar (month, date, day, moonphase), split-seconds chronograph\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eFeatures:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003edisplay back\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eCase material:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003ewhite gold\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eCase diameter:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003e36.5mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eCrystal:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003esapphire front \u0026amp; back\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eStrap:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003ebespoke \u003ca title=\"Watch Strap | Bangkok grey grained leather Watch Strap | A Collected Man Watch Strap\" href=\"https:\/\/www.acollectedman.com\/products\/bangkok-dark-grey-watch-strap\" target=\"_blank\"\u003e\u003cspan style=\"text-decoration: underline;\"\u003e Bangkok grey grained leather\u003c\/span\u003e \u003c\/a\u003e strap from our own collection, Camille Fournet brown leather strap, Patek Philippe white gold deployant clasp\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eLug Width:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003e19 x 13mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eYear:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003e\n\u003cmeta charset=\"utf-8\"\u003e \u003cspan\u003e\u003cspan class=\"ui-provider wd b c d e f g h i j k l m n o p q r s t u v w x y z ab ac ae af ag ah ai aj ak\" dir=\"ltr\"\u003e2007\u003c\/span\u003e\u003c\/span\u003e\n\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eBox \u0026amp; papers:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003ePatek Philippe outer box, inner wooden box, leather folder, additional caseback, setting pin, certificate of origin, service papers (invoice), instructions\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch6\u003eCondition\u003c\/h6\u003e\n\u003cp\u003eThis Patek Philippe Split Seconds Chronograph 5004 is in very good condition throughout.

The movement of this perpetual calendar was based on the Lemania 8810, and was developed in collaboration with Philippe Dufour.\u003c\/p\u003e\n\u003c!-- SECTION BREAK --\u003e\n\u003cp\u003eShortly after starting his eponymous brand, Daniel Roth decided to tackle one of the most classic complications in horology, the perpetual calendar. To help him with this project, he approached none other than Philippe Dufour, who had only just begun his journey as an independent watchmaker. Not only was Dufour highly skilled in this sort of work, but he also happened to live just down the road from Roth's workshop. \u003c\/p\u003e\n\u003cp\u003eTogether, they sought to develop the world’s first instantaneous perpetual calendar, where all the indications would flick into place, rather than gradually move into position. They used the Lemania 8810 as their ébauche, jointly developing a perpetual calendar module which would sit on top of it. According to Dufour, the process was rather laborious, even with his experience working on complicated movements. As he puts it, \"I remember it being hard work. It took me about six or seven months to finish the movement.”\u003c\/p\u003e\n\u003cp\u003eRoth first announced this project at Baselworld in 1991, where he presented a prototype featuring apertures for the day and date. However, as Roth and Dufour found out during the development process, too much energy was required for the indications to jump into place. As such, they replaced the digital display for the day and date with two sub-dials and corresponding sets of hands, in order to decrease the force needed to move all the gears. Evidence suggests that both versions were released at Baselworld in 1993, two years after the project was first announced. \u003c\/p\u003e\n\u003cp\u003eFor this reference 2117, Roth reimagined the perpetual calendar dial layout, foregoing the traditional approach usually adopted by others. The sub-dial at 6 o'clock is used to indicate the date on the periphery, with the year on the inside, sinking lower down into the dial. As for the month and day of the week, these are displayed in two smaller sub-dials, with the former at 3 o'clock and the latter at 9 o'clock.\u003c\/p\u003e\n\u003cp\u003eThe watch has Roth's signature double-ellipse case, while the dial features a striking skeletonised design, which puts the watchmakers' innovative perpetual calendar module front and center. The time, date, and brand signature are displayed thanks to silver, brushed surfaces, which appear to float above the movement. The exposed mechanics display an impressive level of hand-finishing, with vertical brushing, mirror polish and bevelling visible on most of the surfaces. The baseplate features a traditional hand-engraving, in a floral pattern, which adds another level of ornate decoration. The lance-shaped hands are crafted from blue steel, another visual inspiration from the Abraham-Louis Breguet. \u003c\/p\u003e\n\u003cp\u003eAs mentioned previously, the watch is powered by a reworked Lemania 8810 ébauche. On top of the automatic movement sits a perpetual calendar module, jointly developed by Roth and Dufour, and assembled within the brand's Vallée du Joux workshop. The movement is subtly finished, with chamfering on some of the angles, as well as polishing and decoration, in the form of Geneva striping. The rotor is made out of solid gold, and engraved by hand.

This example features a dial with German indications for the days and months, alongside the typical balanced layout, svelte profile, and classic look that has come to characterise the reference.\u003c\/p\u003e\n\u003c!-- SECTION BREAK --\u003e\n\u003cp\u003eCreated at the turn of the century, this reference 3940 is an excellent example of the neo-vintage movement, marking an exciting period of rebirth for the watch industry. At 36mm, the watch is a size that is reminiscent of vintage Patek Philippe references, further adding to its charm.\u003c\/p\u003e\n\u003cp\u003eAn elegant piece that has found itself in high demand from collectors in recent years, the reference 3940 is perhaps the most iconic perpetual calendar of the modern era. The design focuses on balance, with its three registers showing various functions neatly balanced out. The sub-dial at three o'clock shows the leap-year counter and the months (in German), in a slightly recessed sub-register, giving depth to the otherwise lightly brushed, silver dial. In a similar fashion, the months and day\/night indicators are placed at nine o'clock. The silver moon-phase is found at six o'clock, surrounded by the days of the month.\u003c\/p\u003e\n\u003cp\u003eThe dauphine hands add a touch of sharpness to what only can be described as a beautifully executed timepiece. Evidence suggests that the 3940 dials were produced by Stern Frères, who provided many to Patek Philippe during this period. Some of the characteristics associated with a third series example, such as the \"σ SWISS σ\" printed in line with the outer minute track and hallmarks stamped on the reverse of all four lugs, can be found on this model. This grey gold example is especially understated in styling and size, its slim case is matched by an equally slim movement.\u003c\/p\u003e\n\u003cp\u003eRepresenting the best of Swiss design, the movement itself is no less a technical feat. This example has an open case back, which reveals the fantastic hand-finishing, including Côtes de Genève with its quality guaranteed by the Genevan Seal. The ultra-thin self-winding movement, powered by an off-centre 22k gold micro-rotor, has been in use by Patek Philippe since the 1970s, and has been incorporated into a number of their modern perpetual lines.\u003c\/p\u003e\n\u003cp\u003e \u003cbr\u003e\u003c\/p\u003e\n\u003c!-- SECTION BREAK --\u003e\n\u003ch6\u003e\u003cstrong\u003eCloser look \u003c\/strong\u003e\u003c\/h6\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eBrand:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003ePatek Philippe\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eModel:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003ePerpetual Calendar ref. 3940G-017\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eMovement:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003eautomatic calibre 240 Q aut.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eFunctions:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003eperpetual calendar (leap year indicator, month, date, day; moonphase), day\/night indicator, hours, minutes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eFeatures:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003edisplay back, German dial\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eCase material:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003ewhite gold\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eCase diameter:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003e36mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eCrystal:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003esapphire front \u0026amp; back\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eStrap:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003e\n\u003ca href=\"https:\/\/www.acollectedman.com\/products\/_bruges\" title=\"View our saffiano strap in burnished sienna\" target=\"_blank\"\u003e\u003cspan style=\"text-decoration: underline;\"\u003esaffiano strap\u003c\/span\u003e \u003c\/a\u003e from our own collection, Patek Philippe black alligator strap, Patek Philippe grey gold deployant clasp\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eLug Width:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003e18 x 14mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eYear:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003ec. 2001\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eBox \u0026amp; papers:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003ePatek Philippe outer cardboard box, Patek Philippe outer paper box, Patek Philippe inner wooden box , leather folio, Certificate of Origin, movement manual, advertising\/branding material\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch6\u003eCondition\u003c\/h6\u003e\n\u003cp\u003eThe case of this 3940G has been very well preserved, with no obvious signs of polishing.

The case is a combination of titanium and platinum, which gives the watch a lighter feel, as the bracelet is constructed from brushed titanium, with polished platinum links and titanium folding clasps. This creates an attractive interplay with the light as the bracelet shifts on the wrist.\u003c\/p\u003e\n\u003cp\u003eThe dial is a deep, satin-brushed blue with subtly recessed sub-dials, demonstrating the day, month, date, and moonphase. Smaller leap year and day\/night indicators can be found below the larger day and month sub-dials, overlapping slightly but providing an added overall symmetry. This is paired with luminescent hour hands and indices, in a nod to the modern style of this Royal Oak. On the date sub-dial, the 31st marker has a red accent, which improves readability between the 31st and 1st days.\u003c\/p\u003e\n\u003cp\u003eThe movement that powers this reference 26586 is the self-winding calibre 5133, which is in part based on the calibre 2120, used in the Royal Oak \"Jumbo\". This calibre 5133 has been heavily simplified and is made up of just 256 parts, with a diameter of 32mm. The reference 26586 has an overall case height of 6.3mm, and a diameter of 41mm, giving the watch a significant presence on the wrist.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003c!-- SECTION BREAK --\u003e\n\u003ch6\u003e\u003cstrong\u003eCloser look \u003c\/strong\u003e\u003c\/h6\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eBrand:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003eAudemars Piguet\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eModel:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003eRoyal Oak Perpetual Calendar Ultra-Thin ref. 26586IP.OO.1240IP.01\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eMovement:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003eautomatic calibre 5133\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eFunctions:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003eperpetual calendar (year, month, date, day), moonphase, night and day indicator, hours, minutes\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eFeatures:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003erecessed dubdials, stick hands, display back, blue dial, luminescence\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eCase material:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003etitanium \u0026amp; platinum\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eCase diameter:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003e41mm\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eCrystal:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003esapphire front \u0026amp; back\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eBracelet:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003eAudemars Piguet titanium integrated bracelet (18 links of which 5 are removable)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eLug Width:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003e-\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eYear:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003ec. 2019\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eBox \u0026amp; papers:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003eAudemars Piguet outer box, Audemars Piguet inner wooden winding box with instructions, winding key, warranty booklet, International Warranty Card\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch6\u003eCondition\u003c\/h6\u003e\n\u003cp\u003eThis Audemars Piguet Royal Oak Perpetual Calendar Ultra-Thin is in very good condition throughout.

Lange \u0026amp; Söhne. While the brand had previously created perpetual calendar and chronograph pieces separately, this was the first time that all three complications were combined into a single watch. While the watch was first introduced in 2016, this reference 740.056 was released later in 2019, combining a light salmon dial with a white gold case.\u003c\/p\u003e\n\u003cp\u003eThe dial retains the classic Datograph layout. It features a carefully designed dial, which perfectly balances the different elements throughout. The date aperture and combined month\/day-chronograph-function sub-dials form an equilateral triangle, with the central point being the pinions in the middle, which hold the hands in place. The sub-dials themselves are stepped, allowing each ring of information to be distinct from the others, while a combination of thinner blue hands for the chronograph functions and thicker leaf-shaped hands for the months and days give further visual separation. A moonphase also sits just above 6 o'clock, its deep blue complementing the salmon tones of the dial.\u003c\/p\u003e\n\u003cp\u003eTurning the watch over reveals the impressive architectural depth of the calibre L952.2, which is made from 729 parts. The challenge with this movement was for them to maintain the aesthetics of the L951.1, the original Datograph movement, while also keeping the proportions in mind, as well as adapting the movement to include a tourbillon.\u003c\/p\u003e\n\u003cp\u003eOn most watches, the tourbillon complication is placed prominently on the dial, but with this reference 740.056, the tourbillon cage is given pride of place at 6 o'clock on the reverse of the watch, featuring a sharply finished and polished carriage and bridge. The three arms of the tourbillon are hand finished and excellently bevelled, with polishing from all sides. Additionally, it features a stop-tourbillon mechanism first introduced by the brand in 2008, which gently stops the balance wheel at the pull of the crown, allowing for more accurate time-setting.\u003c\/p\u003e\n\u003cp\u003eAs is the case with all of A. Lange \u0026amp; Söhne watches, the movement is made from German silver, and features beautifully polished and finished parts, with brushed and chamfered levers, perlage decoration on the base plate, and Geneva stripes. In keeping with the many complications that this watch houses, the watch has a diameter of 41.9mm, and is 14.6mm thick, making it an assertive presence on the wrist.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eIf sold within the United Kingdom, this A.

Beautifully textured and rare, it features the hallmarks of the reference, such as the recessed subsidiary registers, as well as some of the case redesigns Audemars Piguet made later in the series, to the aid of improved water resistance. This watch comes with a full set of box and papers.\u003c\/p\u003e\n\u003c!-- SECTION BREAK --\u003e\n\u003cp\u003eStill very much in the throes of the quartz crisis, complicated watchmaking was hard to come by as brands struggled merely to survive. However, it was in the middle of this, in the late 1970s, that intrepid watchmakers at Audemars Piguet worked in secrecy, modifying the calibre 2120, to create what would become the world’s thinnest self-winding perpetual calendar. When presented with the finished product, Georges Golay, the brand’s chief executive officer and the man who had green-lit the Royal Oak a few years prior, decided to take yet another risk and put it into production. The Quantième Perpetuel, mated to the now iconic stepped bezel case designed by Jacqueline Dimier, went into production in 1978 and is widely credited with seeing the brand through this period of crisis.\u003c\/p\u003e\n\u003cp\u003eWhile several references were in production simultaneously, the reference 25657 was part of the brand’s catalogue between 1982 and 1993, making it one of the earliest. This is one of the 128 examples that were forged from platinum, and features all the hallmarks, including the recessed subsidiary registers. The white metal case serves to further accentuate what is already a remarkably striking ‘Tuscan’ blue dial. It wears a granular texture that gives the blue dial added depth. The outer chapter, as well as the subsidiary registers feature a smooth texture. While the hour markers are applied, the outer chapter is printed in white, as are the scales on the subsidiary registers. They feature simple, stick hands, same as the ones indicating the hours and minutes.\u003c\/p\u003e\n\u003cp\u003eThe register at 12 o’clock indicates the month of the year while the ones at 3 and 9 o’clock display the date and day of the week respectively. The register at 6 o’clock features the moonphase, with the brand mark and the word ‘Automatic’ printed on.\u003c\/p\u003e\n\u003cp\u003eWhile the reference is one of the earliest, the case on this particular watch features a number of design improvements that came later in the series’ run. This includes a flatter stepped bezel and caseback, that had been redesigned to improve water resistance. These changes also included better protected correctors.

Lange \u0026amp; Söhne catalogue, and their first use of the instant-jump calendar indication. Only 100 pieces were made in platinum. The watch marks a fascinating point in the history of modern Lange watches.\u003c\/p\u003e\n\u003c!-- SECTION BREAK --\u003e\n\u003cp\u003eThis Tourbillon Perpetual Calendar reference 720.025F was launched in 2012, introducing a number of elements that had never been seen before in A. Lange \u0026amp; Söhne watches. This was the first Lange watch to feature a tourbillon with automatic movement, as well as instant-jump calendar indications. This is an especially limited edition of 100 watches that were created in platinum. The series was followed by the Handwerkskunst edition in 2013, and the 25th Anniversary edition in 2016.\u003c\/p\u003e\n\u003cp\u003eThe arrangement of the dial is typical for automatic Lange 1 pieces, with the positions swapped between the oversized date window and the hour and minute display, which are placed on the left and right respectively. The seconds sub-dial is integrated with the moonphase, which is set at a slanted angle instead of the typical horizontal orientation. Meanwhile, the power reserve indication has been removed completely, instead replaced with a retrograde day display to the left of the dial. The change was made to the dial so that the wearer would not have to completely pull back their sleeve to view the time, but could still read the time quickly when glancing down.\u003c\/p\u003e\n\u003cp\u003eFurther additions can be seen with the month ring, which can be found on the periphery of the dial, where the months are indicated by a small triangle pointer near the bottom of the dial, with a small leap year aperture placed directly above, marking the cycle. The calendar mechanism was built around the tourbillon, with the entire calibre integrating the gear train, calendar, and automatic winding features.\u003c\/p\u003e\n\u003cp\u003eThe watch is driven by the calibre L082.1, and the tourbillon complication can be seen through the sapphire caseback, set at the bottom of this intricately finished and decorated movement. The golden rotor is engraved with \"A. Lange \u0026amp; Söhne\", and the tourbillon bridge is hand-engraved with initials instead of the typical floral decoration. As is the case with all of A. Lange \u0026amp; Söhne watches, the movement is made from German silver, and features beautifully polished and finished parts, with brushed and chamfered levers, perlage decoration on the base plate, and Geneva stripes.\u003c\/p\u003e\n\u003c!-- SECTION BREAK --\u003e\n\u003ch6\u003e\u003cstrong\u003eCloser look \u003c\/strong\u003e\u003c\/h6\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eBrand:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003eA.

Bearing Genta's favoured octogonal shape, the watch is an excellent representative of the designer's prolific and visionary body of work, and is an excellent, if lesser-known addition to a collection focused on neo-vintage perpetual calendars.\u003c\/p\u003e\n\u003c!-- SECTION BREAK --\u003e\n\u003cp\u003eGérald Genta is a designer that needs little introduction to those in the watch world. Perhaps most famous for designing the Royal Oak and Nautilus pieces for Audemars Piguet and Patek Philippe respectively, Genta's designs also included the Universal Geneve Polerouter, the IWC Ingenieur, and the Seiko Locomotive. The last piece pays tribute to some of his most successful designs, and Genta had a very close relationship with the brand's president, Reijiro Hattori.\u003c\/p\u003e\n\u003cp\u003eGenta and Hattori were so close that Hattori suggested that the designer should branch out on his own, lighting the spark that would later become the Gérald Genta brand. As Evelyne Genta recalls, Seiko once advertised a Genta-designed watch as having been produced by the same person who was behind the Royal Oak. “In those days – and we go back a long, long time – Audemars Piguet took offence at that and they wrote a rude letter to the Japanese,” she says. “You don’t write letters to the Japanese, so they said to my husband, ‘Make your own brand.’” This would go on to become the Gerald Genta brand, which this perpetual calendar falls under.\u003c\/p\u003e\n\u003cp\u003eOnce Genta had opened his own manufacture in 1969, starting with just seven people and growing to 250 at its height, they were soon making their own models while also producing pieces, such as the Cartier Pasha, for other brands. The Genta-branded pieces of this time demonstrate his real passion for complications and classical horology. According to Evelyne, it was the first brand to reintroduce perpetual calendars after the Quartz Crisis; the same with retrogrades, minute repeaters and grand sonneries.\u003c\/p\u003e\n\u003cp\u003eIt comes as no surprise that the octagon, Genta's favourite shape, is a central feature of the case in this instance, with slight nautical influences, as can be seen from the ship's wheel-style ridges. The dial of this piece is openworked, giving the wearer a glimpse into the complex workings of this perpetual calendar. The sub-dials are laid out in an intuitive manner, with month, date, and day indications at 3, 6 and 9 o'clock respectively. A leap year indicator is placed in the month sub-dial, with cutouts in the shape of a stylised cross. A minimalistic, modern moonphase sits at 12 o'clock, made out of lapis lazuli and with the 'gérald genta' signature printed at the top of the sub-dial. It is generally understood that the signature stylised with a lowercase 'g' came from an earlier time of production.\u003c\/p\u003e\n\u003cp\u003eTurning the watch over reveals the automatic calibre GA1 1303, an ornately decorated movement with wheels, bridges, and other components all finished to a high standard. At 35mm, the watch is on the smaller side, in keeping with its neo-vintage origins, and sits comfortably on the wrist.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eIf sold within the United Kingdom, this Gerald Genta Perpetual Calendar will be subject to 20% VAT\u003c\/em\u003e\u003c\/p\u003e\n\u003c!-- SECTION BREAK --\u003e\n\u003ch6\u003e\u003cstrong\u003eCloser look \u003c\/strong\u003e\u003c\/h6\u003e\n\u003ctable\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eBrand:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003eGerald Genta\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd width=\"63\"\u003eModel:\u003c\/td\u003e\n\u003ctd width=\"213\"\u003ePerpetual Calendar ref.
