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 15450SR.OO.1256SR.01 was added to the collection in 2016. Both case and bracelet are done in a combination of stainless steel and pink gold. The dial is silver.
