When developing its own automatic chronograph movement, Hublot wanted it to be, like all its creations, the first, different and unique. As the soul of the watch, this “open heart” movement reveals its completely reinvented design, with a double coupling system and column wheel on the dial side, as well as a 72-hour power reserve. Its construction consists of 354 components that have been simplified to the maximum to improve its reliability and robustness. A master of fusion and an alchemist of precious metals, Hublot has developed a new gold color that features a warmer tone than traditional 18K 5N gold. Specifically, this exclusive alloy, dubbed King Gold, contains platinum, and lends itself perfectly to all kinds of polishing and satin finishing operations. In Hublot watches, it is combined with the most unexpected materials, such as high-tech ceramic, rubber or carbon.
