Audemars Piguet Tourbillon Extra-Thin

Audemars Piguet's Royal Oak Tourbillon Extra-Thin 26522ST.OO.1220ST.01 is a steel watch measuring 41 mm across. Inside the case is the hand-wound Calibre 2924, a movement built around a tourbillon regulator paired with a power reserve display. The plum-toned dial carries the brand's Evolutive Tapisserie pattern, a sunburst variation on the familiar Royal Oak texture, and it sits under a sapphire crystal. Hours and minutes are the only other functions, keeping the layout uncluttered around the tourbillon carriage. The watch is fitted on a steel bracelet closed with an AP folding clasp. Water resistance is a more modest figure here: the case is rated to 50 metres.
