Patek Philippe Perpetual Calendar Ref. 5140J

This Patek Philippe Perpetual Calendar 5140J in yellow gold embodies timeless elegance with a discreet yet sophisticated appeal. Introduced in 2006, the 5140 reference brought a modern touch to Patek Philippe’s esteemed collection of perpetual calendars, succeeding the legendary 3940—an icon that set the standard for contemporary perpetual calendar designs.

Its 18-carat gold case features a refined 37.2mm diameter, a slim 9mm profile, and a smoothly rounded bezel, adhering to Patek Philippe’s signature proportions. With a lug-to-lug measurement of 46mm, the watch effortlessly slides under a dress shirt cuff, exemplifying classic sophistication.

The Patek Philippe Perpetual Calendar 5140G is driven by the in-house Caliber 240Q, a mechanical automatic movement with a micro-rotor. This ultra-thin, self-winding movement offers a power reserve of 38–45 hours and has been the cornerstone of Patek Philippe’s perpetual calendars for over four decades. Designed for precision and longevity, its perpetual calendar complication remains accurate without adjustment until the year 2100.
