Audemars Piguet Selfwinding Chronograph

Audemars Piguet's Royal Oak Offshore Selfwinding Chronograph, reference 26420TI.OO.A027CA.01, is a chronograph with a 43 mm titanium case. The case measures 14.4 mm thick and the dial sits under a sapphire crystal. The blue dial pairs with the self-winding Calibre 4401, visible through the movement's flyback chronograph mechanism, which also carries small seconds and a date function. Titanium keeps the case light on the wrist despite its size. A blue rubber strap closes with a titanium pin buckle, and AP's interchangeable strap system allows a swap to the additional black rubber strap supplied with the watch. The 100 metre water resistance rating holds even with either strap fitted.
