Launched as a limited edition at the Patek Philippe grand exhibition “Watch Art” held in Tokyo in June 2023, Reference 5330 enters the manufacture’s regular collection. It is distinguished by a patented world first: a date display synchronized with local time; that is, the time in the time zone selected at the 12 o’clock position on the city disk and indicated by the center hands.

To make the user experience as practical and comfortable as possible, Patek Philippe tasked its engineers with coupling the date display mechanically with the local time with no need for correction. Meeting this challenge required that the date adjust automatically in the two situations entailing a change: past midnight, when the date advances to that of the following day; and when crossing the International Date Line (in the middle of the Pacific Ocean) from west to east, where the date goes back by a day.
