Annual Calendar Complication NEW 2026

The Patek Philippe Annual Calendar is a complicated watch that displays the date, the day of the week and the month. Its mechanism distinguishes between months of 30 and 31 days and needs one manual correction a year, at the end of February.

This reference 5326G-001 has a 41 mm white gold case with a white gold bezel and sapphire glass. The grey dial has Arabic numerals, a moon phase, small seconds and a second time zone, driven by the automatic calibre 31-260 PS QA LU FUS 24H with a 48-hour power reserve. The watch is from 2026, new and unworn, and comes with box and papers.
