Audemars Piguet Tourbillon Openworked

Audemars Piguet's Tourbillon Openworked, reference 26600CR.OO.D009KB.01, comes in a rose gold case measuring 41 mm across. The case combines pink and white gold, giving the watch its two-tone finish. A sapphire crystal covers the openworked dial, which shows the hand-finished tourbillon movement in different shades of grey. Inside is calibre 2948, a skeletonised movement built around the tourbillon complication. The construction leaves the hours and minutes functions visible alongside the escapement. A grey rubber-coated strap closes with an 18-carat white gold folding clasp. The case is rated to 30 metres of water resistance.
