Patek Philippe 3940 Perpetual Calendar

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.

The Patek Philippe 3940 Perpetual Calendar is understated both in styling and case-size. With its - by today's standards - modest 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.

Representing the best of Swiss design, the movement is a technical feat. 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. Timeless, elegant and discontinued - the reference 3940 is an investment for life, to be worn - and appreciated, daily.
