For the first time, Patek Philippe combines its patented Annual Calendar with the Travel Time display system, introducing an innovative model that seamlessly manages date changes for local time. The new self-winding Caliber 31-260 PS QA LU FUS 24H movement, with eight patented advancements, ensures precision and efficiency in adjusting the Annual Calendar forwards and backward. Housed in a Calatrava-type white gold case with a Clous de Paris hobnail guilloché pattern, this watch features a vintage-inspired anthracite dial with a grainy texture reminiscent of classic cameras. It includes day, date, and month apertures, two time zones with local and home day/night indications, and moon phases. The 41mm case, with a height of 11.07mm and water resistance of 30m, is complemented by two interchangeable straps: one in beige calfskin with a nubuck finish and the other in black calfskin with an embossed fabric pattern and beige topstitching. A fold-over clasp secures the strap, blending technical innovation with timeless style.
