Audemars Piguet Royal Oak Skeleton 41 Ref. 15407ST. The Royal Oak Double Skeleton Balance addresses these stability problems by fixing a second balance-spring assembly on the same axis. The new, patent-pending "Dualbalance" structure involves an extremely complex manufacturing procedure in return, however, for an excellent result: a marked improvement in precision and stability. Steel case, sapphire crystal and back with anti-reflective treatment, screw-down crown. Slate gray, skeletonized dial, applied hour markers and rose gold Royal Oak hands with luminescent coating
