Audemars Piguet 15407ST.OO.1220ST.01 (Pre-owned - Good) — USD 159,000 on eBay

The Audemars Piguet Royal Oak Double Balance Wheel Openworked reference 15407ST.OO.1220ST.01 represents a skeletonized interpretation within the Royal Oak collection. This particular reference distinguishes itself through its openworked dial construction, which exposes the underlying movement architecture while maintaining the collection's characteristic octagonal bezel design. The 41mm stainless steel case houses the automatic caliber 3132 movement, providing a 60-hour power reserve. The watch features a fixed octagonal bezel and sapphire crystal, with water resistance rated to 50 meters. The skeletonized dial treatment allows visibility of the movement's components, while a matching steel bracelet completes the construction. This reference appeals to collectors seeking technical display watches within the Royal Oak lineup. Production commenced in 2016, positioning this model among the contemporary offerings in the series. The combination of skeletonized dial work with stainless steel construction provides an entry point into openworked complications while maintaining the fundamental design elements of the broader collection.
