Audemars Piguet Royal Oak Skeleton 15305ST

A 2011 discontinued Royal Oak Skeleton Openworked 15305ST 39mm features a ststeel case and a mesmerising open-worked skeleton dial in slate grey. Produced for only a few years this watch is more sought after by Royal Oak aficionados than the more precise 15407ST. This watch is powered by the in-house movement Calibre 3129 which offers 60hrs of power reserve covered by a glare-proof sapphire crystal and caseback.
