Audemars Piguet Selfwinding Chronograph

Audemars Piguet Royal Oak Offshore Selfwinding Chronograph 26231ST.ZZ.D027CA.01 is a chronograph with a 37 mm steel case, sized for a woman's wrist. The case measures 12.4 mm thick. A sapphire crystal covers the blue dial, which carries a date window and a small seconds subdial alongside the chronograph counters. The watch is set with diamonds, in keeping with the model's convention-defying mix of materials and colour. Calibre 2385 drives the watch, a self-winding movement built into the Royal Oak Offshore case. It fastens to a blue rubber strap secured by a steel folding clasp. Water resistance is rated to 50 metres.
