The Patek Philippe reference 3940 stands out as one of Patek Philippe's most iconic models ever created. Introduced in 1985 under the guidance of Philippe Stern, it represented a notable departure in design for the brand's classical perpetual calendar models. During its production period, it ranked among Patek Philippe's longest-running references, with production halting around 2007. The sleek, stepped and finely designed 36 mm diameter Calatrava case infuses the watch with a distinct contemporary elegance, while the calendar functions on the dial are communicated through subdials rather than apertures. Fuelled by the groundbreaking ultra-thin caliber 240, which introduced Patek Philippe's inaugural use of a micro-rotor, it facilitated the creation of an elegant and remarkably slim case that hugged the wrist snugly.
The present reference 3940 in yellow gold, however, sits in a league of its own. Fresh to the market and, to the best of our knowledge, the second example to appear at international auction, this watch is among the rare special production pieces officially authorised as an “out of production” creation. The present example is fitted with a black dial produced specifically for this sub-reference, utilizing the dial typography of reference 5140 and accented with yellow gold indexes to complement the yellow gold case. Distinguished by its highly individual aesthetic, this watch ranks among the most compelling Patek Philippe perpetual calendars of the 21st century.
