Introduced in 2012, the Royal Oak Ultra Thin Tourbillon pairs the classic Royal Oak aesthetics with a hand-wound movement with tourbillon escapement. It is the first Royal Oak with no additional complications to be fitted with such a highly-valued escapement - earlier versions like the 1997 limited, the 1999 Tradition d'Excellence and the later Chrono Tourbillon and Concept watches all featured additional functions. Reference 26522OR.OO.1220OR.01 was added to the collection in 2018. It features a pink gold case and a blue dial with sunburst "Tapisserie Evolutive" pattern.
In-house Audemars Piguet movement with tourbillon escapement and indicator for the 70 hours power reserve on the back.
