The 20.09 Tourbillon is a special subscription piece that combines the best of various processes we've developed - Mosaic, HyCeram embedded sapphire, Sapphire crystal hands, bicolour bridges - and takes our partnership with Schwarz Etienne even further.

It is powered by the Cal. TSE.M1, a unique, skeletonised execution of Schwarz Etienne's flying tourbillon movement which reverses the movement so the barrel, micro-rotor, flying tourbillon and timekeeping hands are all visible from the dial side. The 20.09 also features our first 22mm bracelet with curved ends and quick release pins.
