The Audemars Piguet Royal Oak Selfwinding Chronograph reference 26715ST.OO.1356ST.02 is a contemporary 38mm luxury sports watch crafted from stainless steel. This model represents a refined evolution of the iconic Royal Oak design, featuring a case thickness of 11mm and a signature octagonal bezel secured by eight hexagonal screws. The timepiece is characterized by its grey dial decorated with the Grande Tapisserie pattern, which is complemented by silver-toned chronograph counters and white gold applied hour-markers. The integrated stainless steel bracelet includes an AP folding clasp, and the watch provides a water resistance of 50 meters.
At the heart of this timepiece is the self-winding Calibre 2385 movement, which powers the watch’s practical complications. These include a central chronograph seconds hand, a 30-minute counter at 3 o’clock, and a 12-hour counter at 9 o’clock. Additionally, a date aperture is positioned between 4 and 5 o’clock, and a small seconds sub-dial is located at 6 o’clock. The movement operates at a frequency of 3Hz and offers a power reserve of approximately 40 hours.
General reviews of the 26715ST.OO.1356ST.02 frequently praise its versatile 38mm size, noting that it provides a balanced and ergonomic fit for a wide range of wrist sizes compared to the larger 41mm models. The grey dial is often highlighted for its sophisticated “tone-on-tone” aesthetic and its ability to shift in appearance under different lighting conditions. While the Calibre 2385 is respected for its slimness and established history, some enthusiasts note that it lacks the flyback function and longer power reserve found in Audemars Piguet’s newer in-house chronograph movements. Overall, it is highly regarded as a high-performance timing instrument that maintains the classic Gérald Genta design language.
