In 2022, Audemars Piguet released the new and improved Royal Oak 15510, an upgrade from the previous 15500 model. This particular reference, 15510OR.OO.1320OR.01, features a stunning Pink Gold case and bracelet, complemented by a Blue dial. The watch is powered by the self-winding caliber AP 4302, which includes a unique rotor to celebrate the 50th anniversary of the Royal Oak collection.
