The Royal Oak Extra-Thin Tourbillon, introduced in 2012, blends classic Royal Oak style with a hand-wound tourbillon movement, marking the first time this complication appeared without additional functions unlike predecessors such as the 1997 limited edition, the 1999 Tradition d'Excellence, or various Concept and Chrono Tourbillon models. This 2016 limited edition, created for American retailer Westime, features a pink gold case, matching dial, and a bezel set with 32 baguette-cut diamonds. While the production total for this diamond-set piece is unknown, the non-diamond version (26515OR.OO.1220OR.01) is limited to 25 units.
