Setting
Building on its heritage and past developments while looking to the future, Audemars Piguet has reimagined the perpetual calendar mechanism with ergonomics in mind.
To enhance user’s experience and streamline the design of the case, AP’s engineers have created an easier and more intuitive correction system entirely controlled via the crown, to make this high complication adjustable anywhere without tools and without risk of damage.
A new ergonomic perpetual calendar
Audemars Piguet has rethought the perpetual calendar, which mechanically reproduces the movement of the celestial bodies, with ergonomics at its heart to adapt to evolving lifestyles and open up new technical and design avenues.
