The Royal Oak Ultra Thin Tourbillon debuted in 2012, combining the iconic Royal Oak design with a hand-wound movement featuring a tourbillon escapement. This was a first for the Royal Oak, as previous versions had extra features like the limited 1997 edition, the 1999 Tradition d'Excellence, and later the Chrono Tourbillon and Concept watches. Staying true to the Royal Oak style, the 26512ST.OO.1220ST.01 model is encased in stainless steel and features a sleek black dial.
