Audemars Piguet Selfwinding Flying Tourbillon

Audemars Piguet's Royal Oak Selfwinding Flying Tourbillon, reference 26730ST.OO.1320ST.06, measures 41 mm across in steel. The grey dial has the Grande Tapisserie pattern and sits under a sapphire crystal. Inside is the self-winding calibre 2950, a movement built around a flying tourbillon that shows the escapement without a supporting bridge above it. This is a special edition within the Royal Oak line, built around that single complication. Hours and minutes are the only other functions the movement gives. The watch is fitted to a steel bracelet closed by an AP folding clasp. Water resistance stands at 50 metres.
