Audemars Piguet Tourbillon Chronograph Openworked Selfwinding

Audemars Piguet's Royal Oak Concept Tourbillon Chronograph Openworked Selfwinding, reference 26587TI.OO.D031CA.01, has a titanium case measuring 44 mm across and 16.15 mm thick. The openworked dial exposes the hand-finished movement beneath a sapphire crystal. Inside is the self-winding calibre 2949, a movement built around a tourbillon and a chronograph, the two standout complications on this reference. As a chronograph, it adds a 30-minute counter and a running seconds display to the usual time-telling functions. The watch comes on a rubber strap fitted with a titanium folding clasp. Water resistance is rated to 100 metres.
