  • Catalogue Essay

    Launched in 1985 under the tutelage of Mr. Philippe Stern, the ref. 3940 is arguably one of the most iconic models that Patek Philippe has ever produced, and marked a design shift for the manufacturer's perpetual calendar models. The slim, stepped, elegant and understated Calatrava case gives the watch a refined yet modern flair.

    Inside, the timepiece is powered by the then ultra-thin cal. 240Q, Patek Philippe’s first movement to use a micro-rotor. Such versatility, lightness and slenderness did not compromise the movement’s exceptional reliability at all, in fact, the timepiece boasts an incredible 48-hour power reserve. Measuring 36mm in diameter, the timepiece is extremely comfortable on the wrist and can be dressed up or down according to the occasion.

    Encased in a lovely yellow gold case, the present watch from circa 1987 is offered with its Certificate of Origin and was subsequently sold in Osaka as indicated by its Patek Philippe Japan registered guarantee, dated August 1994. Bearing a movement number of 770’765 and a case number of 2’839’221, this timepiece is the 104th example from the first series that has resurfaced in the market. Delivered with its full set of accessories, the stunning ref. 3940 at hand is preserved in excellent overall condition, offering collectors a fantastic opportunity to acquire a coveted, elegant and timeless perpetual calendar timepiece.
