The Royal Oak 15450 made its first appearance in 2012. It features a case measuring 37mm across, which makes it 2mm smaller than the earlier 15300; the 15400 introduced in the same year on the other hand is 2mm larger. It is powered by the self-winding caliber 3120, which can be seen through the case back. The dial features AP's signature 'Grande Tapisserie' pattern.
Reference 15454OR.GG.1259OR.01 was added to the collection in celebration of the 40th anniversary of the ladies Royal Oak. It features a case with a new frosted finish, achieved with the use of an ancient Florentine metalworking technique.
