Royal Oak Ultra Thin Tourbillon Titanium / Smoked Blue Evolutive / Yoshida

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 26522ST.OO.1220ST.01 was added to the collection in 2019. This limited edition of 30 pieces was created for Yoshida in Japan and features a titanium case and a smoked blue dial.
