The Audemars Piguet Royal Oak reference 15400ST.OO.1220ST.02 is a contemporary luxury sports watch featuring a 41mm stainless steel case with a thickness of 9.8mm. It is characterized by the collection’s signature octagonal bezel secured by eight hexagonal white gold screws and an integrated stainless steel bracelet with a folding AP clasp. The timepiece is equipped with a silver-toned dial featuring the Grande Tapisserie pattern, white gold applied hour-markers, and Royal Oak hands with luminescent coating. It is powered by the self-winding manufacture caliber 3120, which provides a power reserve of 60 hours and is visible through a transparent sapphire crystal caseback.
In terms of complications, this model provides essential timekeeping functions including hours, minutes, and center seconds, along with a date display positioned at 3 o’clock. The watch features a screw-down crown that supports a water resistance of 50 meters, making it suitable for surface swimming. The movement operates at a frequency of 21,600 vibrations per hour and contains 280 parts, including a 22-carat gold oscillating weight engraved with the Audemars Piguet family crests.
General reviews of the 15400ST often highlight its significant wrist presence due to the increased 41mm case size compared to its 39mm predecessors. It is frequently praised for the exceptional hand-finishing of its integrated bracelet and the light-reflecting qualities of the tapisserie dial. While it is widely regarded as a versatile and iconic investment piece, some critics note that it can be a scratch magnet due to the extensive polished surfaces. Additionally, while the movement is celebrated for its aesthetics and reliability, some owners have noted that its accuracy may not always match the standards of more modern COSC-certified chronometers.
