Audemars Piguet Tourbillon Chronograph Openworked Selfwinding

Audemars Piguet's Royal Oak Concept Tourbillon Chronograph Openworked Selfwinding, ref. 26587TI.OO.D010CA.01, has a titanium case measuring 44 mm across and 16.15 mm thick. The openworked dial exposes the self-winding calibre 2949, which combines a tourbillon with a chronograph, and the finish shows off the mechanism rather than hiding it under a solid dial. A sapphire crystal covers the front. This is a chronograph built around technical display rather than convention, with the tourbillon carriage and chronograph counters both visible from the dial side. It runs on a white rubber strap fitted with a titanium folding clasp; an additional black rubber strap comes with it. Water resistance reaches 100 metres.
