Patek Philippe introduces a groundbreaking watch that combines the patented Annual Calendar with the Travel Time display system for the first time. The technical innovation of the Annual Calendar is that it always indicates the exact date for local time. To achieve this, Patek Philippe engineers developed a new self-winding movement with a Travel Time mechanism that controls the Annual Calendar and enables date correction in both forward and backward directions. The Caliber 31-260 PS QA LU FUS 24H has eight patent requests filed, relating to elements that improve precision, efficiency, reliability, security, and user-friendliness.

The 5326G model has a new Calatrava-type case rimmed with a Clous de Paris hobnail guilloched pattern. The vintage-style dial has an anthracite color and a slightly grainy texture reminiscent of old-timer cameras. The watch displays local and home time indication with day/night indication in apertures, moon phases, and small seconds. The dial features gold applied numerals with beige luminescent coating and a black-gradient rim. The watch comes with two interchangeable straps: one in beige calfskin with a nubuck finish and the other in black calfskin with an embossed fabric motif and beige topstitching. The watch has a white gold case with a sapphire crystal case back, is water-resistant to 30 m, has a diameter of 41 mm, and a height of 11.07 mm. The straps are hand-stitched and come with a fold-over clasp.
