Retrograde Perpetual Calendar Rare Handcrafts reference 5160/500R

With their sapphire case back, protected by a hinged cover, and straight lugs, Officer-style perpetual calendars with a retrograde date hand are among Patek Philippe's most sought-after timepieces – all the more so when the case is entirely hand-engraved. Indeed, on this Rare Handcraft model in rose gold, the centre of the dial, bezel, case middle, crown, hinged cover, lugs, even the clasp and screws for the strap have been richly decorated with manually executed volutes and foliage. Inside this beautifully embellished case, Calibre 26-330 S QR with automatic winding incorporates a stop-seconds mechanism alongside technical innovations for the winding system. The day, leap year cycle and month are shown in windows at 9, 12 and 3 o'clock, completed by a retrograde hand for the date. A precision moon phase display will require correction of a single day after 122 years. Reference 5160/500R-001 is worn on a patinated brown alligator strap with a rose gold folding clasp.
