Audemars Piguet Royal Oak Double Balance Wheel Openworked 41mm White Gold Blue Sapphire Bezel 15412BC.SS.1220BC.02

The Audemars Piguet Royal Oak Double Balance Wheel Openworked, reference 15412BC.SS.1220BC.02, is a 41 mm white gold wristwatch whose skeletonised movement is visible through the dial. It belongs to the Royal Oak collection, recognised by its octagonal bezel, and is presented here in unworn condition as a full set with box and papers. The openworked construction places the movement at the centre of the design, with blue sapphire hour markers and Royal Oak hands set against the exposed mechanism.

The self-winding movement drives hours, minutes, central seconds, and the double balance wheel, and the openworked layout means those components remain visible rather than concealed behind a solid dial. The 41 mm case and bracelet are both in 18k white gold, so case and bracelet share one material and tone, while the octagonal bezel is set with blue sapphires. The blue sapphire markers and bezel sit against the silver-toned openworked dial, creating contrast that aids reading the time. Water resistance is rated to 50 m, and the bracelet closes with an AP folding clasp.
