Audemars Piguet Selfwinding Chronograph

Audemars Piguet's Royal Oak Offshore Selfwinding Chronograph, reference 26425BC.ZZ.D002CA.01, comes in a 43 mm white gold case. The dial is black with a "Méga Tapisserie" pattern and silver-toned counters, and sits under a sapphire crystal. Inside is the self-winding calibre 4401, a chronograph movement with flyback function, small seconds and date. This is a chronograph with a sporting build and a dressier finish where it counts. It runs on a black rubber strap fitted with an 18-carat white gold folding clasp set with diamonds. No water resistance figure is given for this reference, so the case rating stays unstated here.
