Audemars Piguet Double Balance Wheel Openworked

Audemars Piguet's Royal Oak Double Balance Wheel Openworked 15416CD.OO.1225CD.01 is a 41 mm case in deep blue "Bleu Nuit" ceramic. The case houses the self-winding calibre 3132, visible through the openworked dial and finished in rhodium tone. A sapphire crystal covers the dial, which is skeletonized and shows a central seconds hand along with the patented double balance wheel mechanism. The movement's twin balance wheels sit in plain view, set to improve precision and stability. The watch pairs with a matching "Bleu Nuit, Nuage 50" ceramic bracelet, closed by a titanium folding clasp. Water resistance is set at 50 metres, a modest depth that suits a piece built more for the wrist than the depths.
