Remodelled and presented as 42mm and 43mm diameters, the Skeleton X stands apart from other skeleton watches for the emphatically geometric architecture of its movement. Four indexes form an X, framed by a rectangle itself set into the round shape of the case. All with a rarely seen degree of transparency. The new UN-371 movement with 96 hours of power reserve reprises one of the innovations premiered by the Freak Vision in 2018, namely a super-light, extra-wide balance in silicon, with nickel flyweights and stabilising micro-blades. This Skeleton X comes in blue titanium, black titanium, pink gold or Carbonium Gold. Borrowed from aeronautics, Carbonium is a new, ultra-light and sustainable material whose fibres are used in the latest-generation airplanes’ fuselage and wings. Carbonium Gold is a “fusion” of carbon and gold, which gives the case its shimmering, flowing black and gold waves.
