REF. 5326G-001, MOVEMENT NO. 7'578'155, CASE NO. 6'635'579, CIRCA 2023

Reference 5326 marks a significant technical milestone for the manufacturer by combining the travel time complication (1997) with Patek Philippe's annual calendar function (introduced in 1996) for the first time. These two complications work in perfect harmony to create a watch that is not only highly functional and easy to use, but also mechanically complex. A clever patented system that was introduced in 2021 makes it possible to change both time zones solely through the crown, doing away with the need for pushers in the caseband and giving the watch a noticeably sleeker, more streamlined appearance. Most astonishingly, the annual calendar, which only needs to be adjusted once a year in February, is based on local time instead of home time, a completely new idea that allows the calendar to smoothly advance and return in sync with the second time zone.

Technically speaking, the accomplishment is impressive. No fewer than eight new patents filed by the manufacturer highlight the complexity of the automatic calibre 31-260 PS QA LU FUS 24H, which was created especially for this model. The watch has equally striking aesthetics. Despite being firmly modern in spirit, it obviously borrows from Patek Philippe's heritage, especially in the hobnail embellishment of the 41 mm white gold case. This mid-century inspiration is further reinforced by the granular charcoal grey dial, which gives the watch a subtle, warm elegance that contrasts beautifully with its sophisticated mechanics.

Reference 5326G, which is considered a future classic and a source of great pride for the manufacturer, was prominently featured on the cover of the official 2022 Patek Philippe Collection Catalogue.
