The Royal Oak Extra-Thin Tourbillon made its debut in 2012, combining the timeless design of the Royal Oak with a hand-wound tourbillon movement. This was a first for the Royal Oak, as previous models with this prized escapement also had other features, such as the limited edition 1997, the 1999 Tradition d'Excellence, and the later Chrono Tourbillon and Concept watches. In 2017, the collection welcomed the 26516OR.ZZ.1220OR.01, featuring a pink gold case and a bezel adorned with diamonds. The dial has a rich brown hue, adding a touch of sophistication to this already luxurious timepiece.
