The Vacheron Constantin Les Cabinotiers Skeleton Minute Repeater reference 30030 is perhaps best viewed in the context of the long history that chiselled and shaped it. When it was released in early 1994, it marked the convergence of the heritage house’s two proud traditions – ultra-slim minute repeater calibres and skeletonisation. In fact, the reference would be one of the last traditionally skeletonised and engraved ultra-slim minute repeater calibres created by hand the traditional way. As such, it is fitting that it was offered as part of the brand’s most elevated and artistic line of watches, Les Cabinotiers.
It is pertinent to start with the calibre inside – the 1755 was first seen in 1992 and is an ode to the calibre powering the reference 4261 (from 1943), which at the time was the thinnest minute repeater movement. The 1755, standing just 3.28 mm tall, inherited this mantle. There was another reason why it was a rare proposition – it was a minute repeater calibre designed and created in-house based on the 1943 vintage. The 1755 remained in service till 2010 (when it was replaced by the marginally thicker calibre 1731). Throughout its production, the 1755 remained one of the very slimmest minute repeaters in production (till 2016, when Bulgari released its Octo Finissimo Minute Repeater, powered by the 3.12 mm tall calibre 362).
It's believed that 200 examples of the calibre 1755 were created to power three references – the closed dial reference 30010, the perpetual calendar reference 30020, and the skeletonised reference 30030. The last of these, the only one made as part of the Les Cabinotiers collection, is rightly viewed as the ultimate iteration of this calibre. The two variants of the reference were cased in rose gold (30030/000R) and platinum (30030/000P).
After the labour-intensive process of skeletonisation – often as much as halving the metal content of parts like the main plate, bridges and bars – some parts are treated to decoration. The components are engraved in-house – in this era, it was done by now well-known artisans such as Jeanne Valentine Ulrich. The engraving gives the dial- and movement-sides its tracery-like quality, with the frames of bridges appearing as a network of impossibly thin, extensively decorated bridges. It is a style of decoration Vacheron Constantin has honed and perfected since its first skeletonised pocket watch in 1924.
While such skeletonisation can often overwhelm the aesthetic, the Le Cabinotiers artisans have judged it well, employing rose gold wheels and bridges alongside yellow gold wheels and vertically satinated stainless steel levers to attain visual harmony and aid readability. The visible jewels and skeletonization both serve to relieve the exceedingly ornate appearance. The rose gold centre wheel and the barrel are skeletonised to create the brand’s Maltese cross logo, further embellished with floral engraving. All bridges and levers originate from a circular, sectored baseplate that has been skeletonised to the point of invisibility. Where it is visible, this baseplate is engraved.
The black and rose gold hour markers – visually consistent with the yellow gold hours and minutes hands – and the brand mark are applied and float above the movement. The black brand logo and ‘Swiss made’ mark are also printed on the crystal.
On the movement side, the rose gold baseplate is more visible. The bridges emanating from it, such as the one anchoring the minute repeater spring or framing the crown and ratchet wheels, are beautifully engraved. The finger-style bridges of the gear train, as well as the balance and escape bridges, are skeletonised and engraved. The two hammers which strike the two gongs running the periphery of the calibre are black polished.
The treatment provides distinct visual treats on the dial and movement sides. In the first instance, the dance of the sensor and racks for the minutes and hours, as well as the turning of the four-sided minute snail which expresses the quarter hours. On the movement side, the actions of the sensors and racks are translated to the action of the two hammers striking against their respective gongs.
The sound reverberates through the skeletal calibre, bouncing off the sapphire sandwich of the rose gold case and coming alive in spectacular fashion. The sonnerie is both loud and distinct, defying the commonly held wisdom that the best sound signature requires a closed caseback.
The calibre 1755 SQ features a straight-line lever escapement, a monometallic balance and a swan's-neck regulator.
It is housed in a classical, three-part 37mm rose gold case. It features a rounded bezel that sits atop a slim, but rotund midcase. This part is home to the knurled crown (that sits marginally recessed into the case) as well as the minute repeater slider on the left flank. The serial number is freehand engraved on the bottom right flank. The precious metal hallmark is etched on the underside of the minute repeater slider. The sapphire of the caseback is framed by a slim, rounded bezel. The teardrop lugs complete this restrained, classical case.
The Vacheron Constantin Les Cabinotiers Skeleton Minute Repeater reference 30030/000R is one of the last of its kind of watchmaking. It follows in a tradition native to the brand and saw it through in an era when precious few brands were venturing into minute repeater calibres. That it was developed in-house, cased in a classically proportioned case and extensively hand-crafted and finished only adds to the incredible rarity of its proposition.
