Audemars Piguet Selfwinding Chronograph "50th Anniversary"

Audemars Piguet's Royal Oak Selfwinding Chronograph "50th Anniversary", reference 26240ST.OO.1320ST.01, is a chronograph in a 41 mm steel case. The case measures 6.8 mm thick and pairs with a blue dial under a sapphire crystal. Inside is the self-winding calibre 4401, a flyback chronograph movement that also carries small seconds and a date function. The flyback function allows the chronograph to be reset and restarted in one press of the pusher, without stopping first. A steel bracelet closes with an AP folding clasp. It is compact for a chronograph, and legible without excess. Water resistance stands at 50 metres.
