In 2012, the Royal Oak 15450 made its debut with a 37mm case, 2mm smaller than its predecessor 15300. The 15400, released the same year, is instead 2mm larger. The watch runs on the automatic caliber 3120, visible through the back of the case. The dial is adorned with AP's iconic 'Grande Tapisserie' design. In 2016, the 15450SR.OO.1256SR.01 joined the lineup, featuring a mix of stainless steel and pink gold on the case and bracelet. The dial is a sleek silver.
