AN ERGONOMIC AND INTUITIVE ALL-IN-ONE CROWN
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.
