The Audemars Piguet Royal Oak Selfwinding reference 15500ST.OO.1220ST.04 is a contemporary 41mm luxury sports watch crafted from stainless steel. This model features 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 case measures 10.4mm in thickness and includes a glare-proofed sapphire crystal and a transparent caseback that reveals the movement. The silver-toned white dial is decorated with the Grande Tapisserie pattern and features applied white gold hour markers and Royal Oak hands with luminescent coating for enhanced legibility.
The timepiece is powered by the in-house Calibre 4302 self-winding movement, which operates at a frequency of 4Hz and provides a substantial 70-hour power reserve. Its primary complications include hours, minutes, center seconds, and a date display positioned at 3 o’clock. Designed for daily wear, the watch features a screw-locked crown and maintains a water resistance of up to 50 meters.
General reviews of the 15500ST highlight the technical and aesthetic upgrades over its predecessor, the 15400. Collectors frequently praise the Calibre 4302 for its superior finishing, including Geneva stripes and polished bevels, as well as its larger size which better fills the caseback. The dial’s updated design, which removes the Automatic label and utilizes broader markers, is often noted for creating a sportier and more balanced appearance. While the 41mm diameter and integrated lug design provide a significant wrist presence, some critics note that the watch can feel larger than its specifications suggest and that the highly polished surfaces are susceptible to visible scratches.
