3940

Philippe Stern's own favourite, by his account, and the reference that made the perpetual calendar a wearable everyday proposition — 36mm, under 9mm thick, with a micro-rotor movement. It ran for over 20 years.

Common questions

When was the Patek Philippe 3940 produced?

The 3940 was produced from 1985 to 2007.

What movement does the Patek Philippe 3940 use?

The Patek Philippe 3940 runs the Cal. 240 Q, an automatic movement.

How do I check a Patek Philippe 3940 with Watch Safe?

Look up the watch's serial number in the Watch Safe registry to see whether a record exists or a theft flag is attached. A registry search identifies records for a specific serial; it does not authenticate the watch. Authentication is performed in person by an independent expert authenticator, and Watch Safe records and publishes the result.
