Audemars Piguet Royal Oak 15400OR with Aftermarket Full Diamond Replic

In its model number, "15400" is the base model code of this collection, and "OR" indicates that the case is made of 18K rose gold. Different from the original factory base model, which usually features a "stainless steel + metal dial, no diamond setting" configuration, this watch has been retrofitted by a third-party institution—with diamonds fully set on the case, bezel, dial (and in some cases even the bracelet) to create a "Man Tian Xing" (full diamond) visual effect. It is equipped with Audemars Piguet's in-house Calibre 3120 self-winding movement, offering a power reserve of approximately 60 hours and a date display function. With a case diameter of 41mm and water resistance of 100 meters, it also retains the Royal Oak's iconic "octagonal bezel + screw fixation" design.
