Audemars Piguet Royal Oak Selfwinding Perpetual Calendar Openworked

Swiss Haute Horlogerie manufacturer Audemars Piguet is delighted to unveil its new in-house selfwinding perpetual calendar openworked movement, Calibre 7139, which offers a modern take on this classic complication and the age-old artistry of openworking. Designed with ergonomics in mind, it incorporates the brand’s intuitive all-in-one crown correction system – introduced last year to celebrate the brand’s 150th anniversary and features a harmonious calendar display that improves legibility. The openworked components let the light shine through to reveal the movement’s mechanical heart. Calibre 7139 debuts on two 41 mm models: a timeless two-tone Code 11.59 by Audemars Piguet – the first openworked perpetual calendar in the collection – and a Royal Oak uniting titanium and Bulk Metallic Glass (BMG). The two timepieces feature sapphire dials that highlight the movement’s minute craftsmanship and refined architecture. Following in the footsteps of the historic Calibre 5135, which was retired last year, Calibre 7139 opens new technical and aesthetic possibilities for this celestial complication.
