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 2018. It features a stainless steel case and a plum dial with sunburst “Tapisserie Evolutive” pattern.
