Patek Philippe 5140 Perpetual Calendar: A Collector's Guide to Straps
The Patek Philippe 5140 Perpetual Calendar remains a benchmark in high horology since its 2006 debut. Its 37mm case (available in white, 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
At the heart of the 5140 beats Patek’s legendary Caliber 240 Q—a self-winding movement distinguished by a 22K gold micro-rotor and a remarkably slim 3.88mm thickness. The movement boasts Geneva Seal finishing, with exquisite striping and beveled edges visible through the sapphire caseback on later models (earlier versions feature solid casebacks). It offers a 48-hour power reserve and instantaneous date changes at midnight.
Collectors prize the 240 Q for its reliability and timeless design; it remains the base movement for Patek’s modern perpetual calendars, underscoring its enduring legacy.
