Launched in 1985 and discontinued in 2007, the reference 3940 has always been a much-loved watch by collectors and is a significant reference in the modern history of Patek Philippe. The 3940’s reputation is further enhanced by the fact that the then head of the company, Philippe Stern, chose to wear the model as his everyday watch.

Patek Philippe Ref. 3940
Reference 3940, the quintessential perpetual calendar distinguished by its timeless elegance, is undeniably amongst Patek Philippe's greatest classics. Launched in 1985 as replacement for reference 3450, it was at the time the slimmest automatic perpetual calendar wristwatch thanks to the Cal. 240-Q movement with a 22k gold micro-rotor.

An initial series of around 100 pieces were manufactured between 1984 and 1985, the first 25 were especially made for the 225th anniversary of Patek Philippe's retailer Chronometrie Beyer in Zurich, numbered and personalized. Starting in 1985, reference 3940 went into standard production.
