Patek Philippes reference 3940 is undeniably one of the most iconic perpetual calendar wristwatches available to collectors today, and followed a prestigious line of classic models: the reference 1526, the first serially produced perpetual calendar watch from 1941, the 2497 the first perpetual calendar with center seconds from the 1950s, the reference 3448 released in 1962 as the first automatic perpetual calendar and in 1981 the 3450 Patek Philippes first model to feature a leap year indicator. The 3940 was released in 1985 as a replacement to the reference 3450 with a newly designed modern case, which was less angular than its predecessors. Powered by what was then the all-new, ultra-thin calibre 240, Patek Philippes first movement to use a micro-rotor, it enabled an elegant and very thin case that fit tightly to the wrist. The reference 3940 was a smashing success, in production for over two decades, where it appealed to a new generation of enthusiasts who wanted to advance beyond their fathers timepieces.
