Audemars Piguet Royal Oak Selfwinding Perpetual Calendar / 41mm

To mark the beginning of its 150th anniversary celebrations, Swiss Haute Horlogerie manufacturer Audemars Piguet is delighted to unveil a new generation of selfwinding perpetual calendar movement, Calibre 7138, which for the first time ever, enhances user comfort by making the corrections of all functions possible via its “all-in-one” crown. Looking to the future, the brand 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. The result? An intuitive complication that revolutionises the perpetual calendar experience while improving legibility. This new movement makes its debut on a 41 mm Code 11.59 by Audemars Piguet in 18-carat white gold, on two 41 mm Royal Oak models in a choice of stainless steel or 18-carat sand gold, and on three corresponding “anniversary” limited editions of 150 pieces, each featuring subtle aesthetic details that pay homage to the Manufacture’s 150 years of uncompromising craftsmanship. Five years of development went into the creation of this horological feat, which is protected by five patents and offers new creative horizons.
