The DIVER X SKELETON, created in a limited edition of 175 pieces, is equipped with the new manufacture automatic openworked caliber, the UN-372 movement. It comes in a 44mm case, with an ultra-sleek finish and a blue multi layered, X-shaped dial, one of the most complex dials ever made by Ulysse Nardin. All the iconic Ulysse Nardin DIVER codes are in place. Water-resistant to 200 meters, unidirectional rotating bezel, Superluminova on the indexes and hands, central seconds hand for better reading of time underwater. Its inverted, concave bezel with domed sapphire glass is a breakthrough in exquisite watchmaking. The splashes of orange throughout the watch’s design give the DIVER X SKELETON a high-energy, sporty look. It took long technical and meticulous development to build this piece. The precision of its form is amplified by the lightness and transparency of the skeleton movement. Ulysse Nardin used blue Carbonium® on the bezel — a material we also saw in the FREAK X. Carbonium® is an extremely lightweight and durable composite material made from the same fiber that you’ll see used in the aerospace industry, in fuselages and wings — basically the most indispensable elements of modern-day aircraft. Its strength-to-lightness ratio is incomparable, and the marbled effect on its surface is infinitely variable, making each piece unique.
