Audemars Piguet Selfwinding Flying Tourbillon

Audemars Piguet's Royal Oak Selfwinding Flying Tourbillon, reference 26730ST.OO.1320ST.05, is a 41 mm steel watch with a red dial. The case is finished in stainless steel and paired with a sapphire crystal. Inside is the self-winding calibre 2950, which drives the flying tourbillon and the hours and minutes display. This is the standout complication here: a tourbillon without a bridge over the cage, left open for the mechanism to show through the dial. The watch is fitted to a steel bracelet closed with an AP folding clasp. It is short on case dressing but long on finishing, true to the Royal Oak line. Water resistance is rated to 50 metres.
