Audemars Piguet Royal Oak Double Balance Wheel Openworked 15407OR.OO.1220OR.01

Audemars Piguet Royal Oak Double Balance Wheel Openworked (reference 15407OR.OO.1220OR.01) is a 41mm luxury timepiece crafted from 18-carat pink gold. It is defined by its slate grey openworked (skeletonized) dial, which reveals the intricate inner workings of the self-winding Manufacture Calibre 3132. This movement is notable for its patented double balance wheel geometry, featuring two balance wheels and two hairsprings on the same axis to significantly improve precision and stability. The watch features a signature octagonal bezel secured by eight white gold screws and is paired with an integrated 18-carat pink gold bracelet with an AP folding clasp. For low-light legibility, the pink gold hour markers and Royal Oak hands are treated with a luminescent coating. Protected by glareproofed sapphire crystals on both the front and back, the watch has a thickness of approximately 9.9mm and is water-resistant up to 50 meters.
