Patek Philippe Perpetual Calendar

The Patek Philippe Perpetual Calendar, reference 5159R-001, is an exceptionally refined grand complication that combines the prestige of a perpetual calendar with the rare and historically significant officer-style hunter caseback, a design detail that immediately sets this reference apart from every other perpetual calendar in the Patek Philippe catalogue. This certified pre-owned example from 2012 is offered in excellent condition and comes with its full original set, including box, papers, and all original accessories. Crafted in 18k rose gold, the 5159R-001 presents the Perpetual Calendar in a beautifully proportioned 38mm round case measuring 11.80mm in height, with a hinged dust cover protecting the sapphire crystal caseback, a charming and functional throwback to the pocket watch tradition that gives this reference its distinctive officer-style character. The opaline silver dial is elegant and beautifully composed, with Roman numerals, poire-shaped hands, and a retrograde date hand sweeping across the upper register, complemented by day, month, leap year indication, and a moonphase display at 6 o'clock. Powering the watch is the Patek Philippe Calibre 324 S QR, an automatic perpetual calendar movement with central seconds and a retrograde date display, requiring no correction until the year 2100. A movement of exceptional mechanical sophistication, hidden beneath a case that pays homage to watchmaking's earliest traditions.
