Audemars Piguet Selfwinding Flying Tourbillon

Audemars Piguet's Royal Oak Selfwinding Flying Tourbillon, reference 26535PT.ZZ.1220PT.01, has a 41 mm platinum case. The dial is blue with a sunburst Tapisserie finish, set under a sapphire crystal. Inside is the self-winding calibre 2950, which drives a flying tourbillon along with the hours and minutes. The watch is set with diamonds, adding a sharp contrast to the platinum case. Both the bracelet and clasp are made of 950 platinum, with the folding clasp securing the fit on the wrist. The case is rated to 50 metres of water resistance, modest for a watch built around such an intricate complication.
