Audemars Piguet Selfwinding Chronograph

Audemars Piguet's Royal Oak Selfwinding Chronograph 26450ST.OO.1356ST.01-B is a steel chronograph measuring 38 mm across and 11.1 mm thick. The case is stainless steel, a defining material for this collection, and pairs with a matching integrated steel bracelet. A sapphire crystal covers the blue dial. Inside runs the self-winding calibre 6401, a movement developed for this reference. Beyond chronograph timing, the watch adds small seconds and a date display, both set into the dial alongside the chronograph counters. The bracelet is finished in the same steel as the case, giving the watch a continuous, integrated look. It closes with a folding clasp built with three blades for a secure fit. Water resistance on this reference is rated to 50 metres.
