Patek Philippe
Perpetual Calendar 3940 | Yellow Gold

First Series

Regular price


This rare, yellow-gold Patek Philippe 3940, with German dial (from 1987) perfectly illustrates why the reference is so coveted. Understated both in styling and case-size, it carries a highly-desirable 'first-series' dial, with recessed sub-dial registers. With its modest (by today's standards) 36 mm size, and svelte profile matched by a slim, micro-rotor movement, it's arguably one of most elegant offerings of the modern Patek Philippe era.

The dial has three registers, with the 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, opaline dial. This style of sub-register is unique to first-series dials. In a similar fashion, the months and day/night indicators are placed at nine o'clock. The stunning moon-phase is placed at six o'clock, with the days of the month around it. The gold dauphine hands add a touch of masculinity to what only can be described as a beautifully executed dial. Like the recessed subsidiary registers, the classic 'Patek Philippe' font also differs on first-series dials. The overall look is perhaps the most refined and subtle of any 3940, without compromising functionality. 

Representing the best of Swiss design, the movement itself is no less a technical feat. This example has a solid case back, concealing the fantastic hand-finishing, the Genevian coat of arms and stripes, as well as the off-center, 22k gold micro-rotor. The ultra-thin, self-winding 240 Q base movement has been used by Patek Philippe since the 1970s, and continues to beat at the heart of their modern perpetual lines.

Perpetual calendars are the authoritative complications of calendar watches. It's one of watchmaking’s true grand complications, and when Patek Philippe created the ref. 3940 in the mid-80s, perpetual calendars were scarce. With it, a standard for all modern perpetual calendars was established. Timeless, elegant and discontinued - the reference 3940 is an investment for life, to be worn - and appreciated, daily.

Viewings can be arranged in Central London by appointment.
