Audemars Piguet Selfwinding Chronograph

Audemars Piguet's Selfwinding Chronograph, reference 26393ST.OO.A348KB.01, is a steel chronograph with a 41 mm case. The case measures 12.6 mm thick and carries a sapphire crystal over a blue dial with grey counters. Inside is the self-winding calibre 4401, an in-house movement. The watch has a flyback chronograph with small seconds and date, functions built for timing rather than mere display. A steel pin buckle closes the blue rubber-coated strap, matched to the dial's tone. Water resistance is a modest 30 metres, so this is a watch built for the wrist rather than the pool.
