The Audemars Piguet Royal Oak Selfwinding reference 15500ST.OO.1220ST.03 is a contemporary 41mm luxury sports watch crafted from stainless steel. This model features the collection’s iconic octagonal bezel secured by eight hexagonal screws and an integrated bracelet with a mix of satin-brushed and polished finishes. The black dial is adorned with the “Grande Tapisserie” pattern and white gold applied hour markers and hands, all treated with luminescent coating for enhanced legibility. It is powered by the in-house caliber 4302 self-winding movement, which provides a significant 70-hour power reserve and operates at a frequency of 4 Hz.

In terms of complications, this timepiece focuses on essential functionality, featuring central hours, minutes, and seconds, along with a date window located at the 3 o’clock position. The case is equipped with a screw-locked crown and a glareproofed sapphire crystal and caseback, ensuring a water resistance of 50 meters. The movement itself is visible through the exhibition caseback, showcasing high-end finishing such as Geneva stripes and a skeletonized gold oscillating weight.

General reviews of the 15500ST emphasize its bold wrist presence and modern proportions compared to its predecessor, the 15400. Collectors often praise the updated caliber 4302 for its improved power reserve and better fit within the 41mm case dimensions. While some purists prefer the slimmer profile of the 39mm “Jumbo” models, the 15500ST is widely regarded as a robust and versatile daily wearer that maintains the architectural integrity of Gérald Genta‘s original 1972 design while offering a more sport-oriented aesthetic.
