The Royal Oak 15450 made its debut in 2012 with a 37mm case, slightly smaller than the previous 15300. Its 2012 counterpart, the 15400, is 2mm larger. The watch runs on a self-winding caliber 3120, visible through the case back. The dial displays AP's signature 'Grande Tapisserie' design. In 2016, the collection welcomed the 15450OR.OO.1256OR.01, sporting a pink gold case and bracelet with a nickel grey dial.
