Audemars Piguet Selfwinding Chronograph

Audemars Piguet's Royal Oak Offshore Selfwinding Chronograph 26470SO.OO.A002CA.01.A is a 42 mm steel case model known among collectors as the "Vampire". A sapphire crystal covers the black dial. Inside is the self-winding calibre 3126/3840, a movement Audemars Piguet built specifically for this chronograph line. The watch is a chronograph with date and small seconds functions arranged around the black dial. The two-tone black and red rubber strap closes with a steel pin buckle. It is a solid piece on the wrist, with the heft expected of the Offshore range. Water resistance is not stated on the pin buckle or strap, but the steel case and sapphire crystal are built to the Offshore's usual robust standard.
