Audemars Piguet Selfwinding Chronograph "One Drop"

Audemars Piguet's Royal Oak Selfwinding Chronograph "One Drop", reference 26240CE.OO.1225CE.98, is a chronograph with a 41 mm case in black ceramic. The case measures 6.8 mm thick and pairs with a sapphire crystal. Inside is the self-winding calibre 4401, a flyback chronograph movement with small seconds and date. This is a limited edition, part of a special series produced for the "One Drop" auction, with a blue dial set against the black ceramic. The chronograph pushers and crown work alongside a flyback function, useful for restarting timing without stopping the mechanism first. A black ceramic bracelet closes with an AP folding clasp. The case holds a water resistance rating of 50 metres.
