Introduced in 2012, the Royal Oak Extra-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.The present version was added to the collection in 2016 as a limited edition in honor of American AP authorized dealer Westime. It features a pink gold case and matching dial; the bezel is set with 32 baguette-cut diamonds. The number of pieces (to be) made is not known to us at this point; the version without diamonds (26515OR.OO.1220OR.01) is a LE of 25 pieces.
