Patek Philippe Perpetual Calendar 3940J - 39.000€

The Patek Philippe ref. 3940 is often described as the archetype of the modern perpetual calendar—timeless, elegant, and mechanically poetic.

Launched in 1985 and in continuous production for over two decades, the 3940 was a favorite of Philippe Stern himself, who reportedly wore it daily. Its graceful 36 mm case in 18k yellow gold remains a paragon of proportion, housing one of the most refined movements ever crafted by the maison: the self-winding Caliber 240Q, with its legendary micro rotor in 22k gold, visible through the sapphire caseback. Slim, silent, and beautifully finished, the 240Q exemplifies Patek’s philosophy of discreet complexity.

But what truly sets this piece apart is its rare white dial adorned with Roman numerals—a subtle but powerful deviation from the more common baton markers. The black print over the lacquered surface, combined with the classical layout of the calendar functions, gives this model a stately, almost architectural presence. It’s a quiet statement for those who know.

No box, but accompanied by its Extract from the Archives and a 36-month guarantee, this 3940J is a sublime relic of Patek Philippe’s golden age—measured, elegant, and unshakably confident.
