Royal Oak Selfwinding Chronograph

Audemars Piguet Royal Oak Selfwinding Chronograph

The Audemars Piguet Royal Oak Selfwinding Chronograph Ref. 26715ST.ZZ.1356ST.01 combines the Royal Oak’s iconic sports-luxury architecture with refined gem-setting through a 38 mm stainless steel case enhanced by a brilliant-cut diamond bezel. The watch features the instantly recognizable octagonal bezel secured by eight hexagonal screws, integrated stainless steel bracelet, and AP’s signature satin-brushed and polished finishing throughout the case and bracelet surfaces.

Its light blue “Grande Tapisserie” dial creates a vibrant yet elegant appearance, contrasted by silver-toned chronograph counters, white gold applied hour markers, and Royal Oak hands filled with luminescent coating for enhanced legibility. The compact 38 mm proportions give the watch a slimmer, more versatile profile while preserving the strong Royal Oak presence on the wrist. The bezel is set with 40 brilliant-cut diamonds totaling approximately 0.92 carats, adding a refined jewelry dimension without compromising the sporty identity of the model.

The architecture includes glareproofed sapphire crystal, screw-locked crown, solid caseback, and 50-meter water resistance. The integrated stainless steel bracelet flows seamlessly into the case, reinforcing the Royal Oak’s signature angular silhouette and ergonomic comfort.

Powered by the automatic Calibre 2385, the watch delivers hours, minutes, small seconds, date, and chronograph functionality. The movement operates at 21,600 vph (3 Hz), contains 37 jewels and 304 components, and offers approximately 40 hours of power reserve. The chronograph layout includes central chronograph seconds, 30-minute counter, 12-hour counter, and small seconds display, maintaining the balanced sporty aesthetic that defines the Royal Oak Chronograph collection.

This diamond-set light blue Royal Oak Chronograph stands out as one of the most elegant modern 38 mm Royal Oak references, blending haute joaillerie refinement with AP’s unmistakable integrated sports-watch design language. Collectors frequently praise the wearability of the 38 mm case and the way the ice-blue dial changes character under different lighting conditions.
