The Patek Philippe Ref. 3940 stands among the most celebrated perpetual calendar wristwatches of the modern era.
Introduced in 1985, it represents a defining chapter in the history of Patek Philippe’s complicated watches. Its elegant 36 mm case embodies the discreet proportions and timeless sophistication for which the manufacture is renowned. At its heart lies the celebrated self-winding calibre 240 Q, one of the finest ultra-thin perpetual calendar movements ever produced.
The dial presents the day, date, month and moon phases in a remarkably harmonious and legible arrangement.
The leap-year indication further illustrates the technical sophistication concealed beneath its restrained exterior.
The reference 3940 was produced across several series, each distinguished by subtle evolutions in dial configuration and case details, and in 4 materials: yellow gold, rose gold, white gold and platinum.
The reference is particularly admired for the balance between its compact dimensions and the extraordinary complexity of its movement. Its discreet aesthetic perfectly embodies the traditional Patek Philippe philosophy of understated haute horlogerie.
Few perpetual calendars achieve such a refined equilibrium between technical accomplishment and visual purity.
For collectors, this reference offers not only exceptional horological interest but also considerable historical significance.
In 1839, Antoni Patek and Franciszek Czapek founded a company in Geneva to produce pocket watches. After Czapek’s departure in 1845, the association with Adrien Philippe gave birth to the Patek Philippe brand. Patek Philippe is known for its dedication to traditional craftsmanship, innovation, and the production of highly complicated timepieces. A symbol of excellence, its models are sought-after by collectors, with vintage complications often breaking records at auctions.
