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 15450BA.OO.1256BA.01 was added to the collection in 2016 and features a yellow gold case and matching bracelet. The dial is blue. This version is exclusive to Audemars Piguet boutiques.
