Pre-Owned Patek Philippe Grand Complications 5050J

Launched in 1993, the 5050J was Patek's first serially produced perpetual calendar to pair a retrograde date display with an automatic movement. The 35.5mm 18k yellow gold case houses caliber 315 S QR, driving a full perpetual calendar with retrograde date arc, day and month apertures, moon phase at 6 o'clock, leap year indicator, and a 46-hour power reserve — all within a production window that closed in 2002. This example comes with an Extract from the Archives and is fully authenticated and backed by The 1916 Company's 2-year warranty.
