Audemars Piguet 26521BC.ZZ.1220BC.01 description
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.
The 2020 reference 26521BC.ZZ.1220BC.01 is a limited edition of 10 pieces exclusive to the Japanese market. This version has a White Gold case with the bezel set with 32 baguette-cut diamonds; the dial is Black with 'Tapisserie Evolutive' pattern radiating outwards from the axis of the tourbillon.
