Audemars Piguet Double Balance Wheel Openworked

Audemars Piguet's Royal Oak Double Balance Wheel Openworked, reference 15416CE.OO.1225CE.01, has a 41 mm black ceramic case. The case pairs with a sapphire crystal that reveals the openworked, slate grey dial on both sides. Inside is the self-winding calibre 3132, fitted with the Manufacture's patented double balance wheel mechanism. The skeletonized construction shows the central seconds function along with the movement's architecture. Functions are limited to hours, minutes and centre seconds, with the mechanism itself doing the talking. The bracelet is black ceramic, matched to the case, and closes with an AP folding clasp. Water resistance sits at 50 metres.
