Annual Calendar

Innovation That Keeps Perfect Time, Year After Year.
Introduced in 1996, Patek Philippe’s Annual Calendar complication was a horological breakthrough—bridging the gap between simple calendar watches and complex perpetuals. Designed to automatically account for months with 30 or 31 days (only requiring manual correction once per year), these timepieces offer remarkable mechanical intelligence within elegant cases. From classic Calatrava dress styles to sporty Annual Calendar Chronographs, each reference reflects Patek’s mastery of precision and practicality.
