The entire U20 Ultra-Skeleton Tourbillon watch has been conceived as a beautiful mechanical haute horlogerie sculpture. Made of sapphire, carbon and titanium, the U20 is at the forefront of cutting-edge watchmaking. The U20 Ultra-Skeleton Tourbillon makes extensive use of sapphire in both the construction of the movement as well as the case.

Made of sapphire, carbon and titanium, the U20 is at the forefront of cutting-edge watchmaking.

From the movement to the case design, every aspect of the U20 has been conceptualized to allow light to enter the watch and reveal the splendor of the movement’s architecture and tourbillon. The first elements one sees are the raised dome sapphire crystal of the carbon case and the mirror-polished beveled edge of the monobloc titanium lugs, all reflecting the light.
