The Patek Philippe 5140 Perpetual Calendar remains a benchmark in high horology since its 2006 debut. Its 37mm case (available in white, rose, yellow gold, and platinum) houses the ultra-thin Caliber 240 Q movement with perpetual calendar, moon phases, and leap year tracking. Unlike bulkier perpetual calendars, the 5140 slips effortlessly under a dress cuff, making it one of the most wearable high-complication watches ever made.

The Caliber 240 Q
Powering the 5140 is Patek’s ultra-thin Caliber 240 Q, a self-winding movement with a 22K gold micro-rotor. Key features:
- Just 3.88mm thick—remarkable for a perpetual calendar.
- Geneva Seal finishing, with exquisite striping and bevelings visible through the sapphire caseback (on later models; earlier versions had solid casebacks).
- 48-hour power reserve, with instantaneous date changes at midnight.
Collectors praise the 240 Q for its reliability; it’s the same base movement used in Patek’s modern perpetual calendars, a testament to its enduring design.
