Audemars Piguet Double Balance Wheel Openworked

The Royal Oak Double Balance Wheel Openworked ref. 15407OR.OO.1220OR.01 has the octagonal case and integrated bracelet characteristic of the collection, executed in 18-carat pink gold at 41mm with a case thickness of 9.9mm. Its openworked dial exposes the calibre 3132 selfwinding movement, showing hours, minutes and centre seconds through a skeletonized construction. The glareproofed sapphire crystal allows an unobstructed view of the mechanics, and the movement provides 45 hours of power reserve. Water resistance is rated at 50 metres.
