2160/1

As Vacheron Constantin’s first self-winding tourbillon movement, the 188-part Caliber 2160 is exceptionally slim at 5.65 mm and offers an 80-hour power reserve. It utilizes a 22K gold peripheral rotor and a 2.5 Hz frequency, allowing an unobstructed view of the finishing and the hand-bevelled tourbillon carriage through the sapphire caseback, and features a tourbillon escapement.
