It is ultra-lightweight, resists torsion and stands out with its optimal relationship between weight and resistance. This high-tech material is in the form of a fiber mesh embedded in an epoxy resin. Hublot also uses a 3D carbon where the fibers are woven on three planes. Other models use a “frosted” carbon with colored inclusions. Learn more Movements UNICO By developing its own automatic chronograph movement, Hublot wanted it to be – like all of its creations – the first, different and unique. As the soul of the watch, this movement with an “open heart” reveals its completely re-imagined design, with double clutch system and column-wheel from the dial side as well as a 72-hour power reserve. Its construction of 354 components has been simplified as much as possible to improve reliability and robustness. Learn more HUBLOT RAISES THE STANDARDS: 5+5 WARRANTY Our confidence in every watch.
