Audemars Piguet Unveils Next-Generation Perpetual Calendar 'Calibre 7138'

Swiss luxury watch brand Audemars Piguet unveiled new self-winding perpetual calendar movement "Calibre 7138" as the first work in its 150th anniversary commemorative series. This movement is designed with an "all-in-one crown" function applied for the first time, allowing all operations to be controlled with a single crown -- dramatically improving user convenience compared to existing models. This movement will be first installed in the 41mm Code 11.59 by Audemars Piguet and Royal Oak models, and can also be found in "Anniversary" editions limited to 150 pieces each. The "all-in-one crown" innovation: traditional perpetual calendar watches require multiple pushers or correctors to adjust date, day, month, and year individually -- a fiddly process requiring specific sequences to avoid damaging the mechanism; the Calibre 7138 all-in-one crown allows all calendar functions to be adjusted through a single crown using a new intuitive protocol; this reduces adjustment complexity from a multi-step process requiring the watch instructions to a user-intuitive interaction. The 150th anniversary context: Audemars Piguet was founded in 1875 in Le Brassus, Switzerland; the Royal Oak (designed by Gerald Genta, launched 1972) is among the most influential watch designs in history and redefined luxury sports watches; the 150th anniversary celebrations will span multiple new calibers, limited editions, and design innovations throughout 2025.
