Created for the 50th anniversary of the Royal Oak in 2022, the Audemars Piguet Royal Oak Openworked Flying Tourbillon ref. 26735ST.OO.1320ST.01 combines Gerald Genta's iconic design with haute horlogerie. The 41mm stainless steel case, with its octagonal bezel and hand-finished bracelet, reveals the self-winding calibre 2972, openworked and rhodium-toned, with a flying tourbillon at 6 o'clock. Every bridge is visible, from the dial side to the caseback. Offered in new condition, this reference is one of the most desirable Royal Oak complications of the anniversary generation, and a true grail for any collector.
