The Audemars Piguet Royal Oak Selfwinding reference 15450SR.OO.1256SR.01 is a mid-sized luxury sports watch featuring a 37mm case constructed from a combination of stainless steel and 18-karat rose gold. The case measures 9.8mm in thickness and has a lug-to-lug distance of 46.8mm, offering a versatile profile suitable for various wrist sizes. Its iconic octagonal bezel is crafted from solid rose gold and secured by eight hexagonal steel screws, while the integrated bracelet utilizes stainless steel outer links and rose gold center links. The silver-toned dial features the signature Grande Tapisserie pattern, adorned with applied rose gold hour markers and baton hands, both treated with a luminescent coating for legibility in low-light conditions.
The timepiece is powered by the in-house AP Calibre 3120, a self-winding movement composed of 280 parts and 40 jewels. This movement operates at a frequency of 21,600 vibrations per hour and provides a substantial 60-hour power reserve. It features a bi-directional 22-karat gold rotor engraved with the Audemars and Piguet family crests, which is visible through the transparent sapphire crystal caseback. The watch offers practical complications including central hours, minutes, and seconds, along with a date window located at the 3 o’clock position. It is equipped with a screw-locked crown and is water-resistant up to 50 meters.
General reviews of the 15450SR highlight its exceptional finishing and the unique aesthetic appeal of the two-tone steel and rose gold combination. Collectors often praise the 37mm size for its balanced proportions, noting that it wears slightly larger than its dimensions suggest, making it a popular choice for those with smaller wrists or those preferring a more classic fit. The level of detail on the integrated bracelet and the hand-engraved rotor are frequently cited as standout features. While some critics note that the two-tone style is more specialized than full steel models, the watch is widely regarded as a historically significant and versatile timepiece that maintains the legendary status of the Royal Oak collection.
