The "X" in the center of the Universe of Ulysse Nardin. The X factor is the answer to everything: X as an adventure, X as our deepest desires, X for the unknown, X for the forbidden, daring and exciting. SKELETON is the perfect showcase of this new X-ray vision of watchmaking.

First introduced in 2016, the Executive Skeleton Tourbillon was a bold combination of classic watchmaking codes with a hyper-modern, sporty and skeletonized dial.

The shape of the case Skeleton it has now been totally revisited and resized, it has abandoned the 45 mm round case of its precursor, moving on to a more stylized and more elongated shape with a diameter of 42 mm. Presented in four variants: Satin Titanium, Titanium Black DLC, Rose Gold and Carbonium® Gold (which has a slightly larger diameter of 43mm). A material generally reserved for the production of aircraft wings and fuselages, Carbonium® is a super light and high performance material made with carbon fibers.

The dial architecture offers a spectacular view of the movement, which is anchored by a central rectangular bridge with four arms forming an "X". 

Based on the UN-171 movement, the new UN-371 caliber of the Skeleton X family has been completely redesigned. Hand-wound movement, the UN-371 caliber houses a silicon gear and a balance wheel (3Hz) with a power reserve of 96 hours, which can be viewed through a window on the caseback.

All four models are presented on a choice of rubber or alligator straps and are water resistant to 50m.

Lo SKELETON lays bare its bold technology in an exquisite display of the most demanding technique of watchmaking. Inner beauty is unveiled and no longer hidden: bold and powerful, it is an X-ray interpretation of the future of watchmaking design, in which we see everything, including the architecture and the workings of time.

The prices of the 4 models start from 17.500 EURO up to 29.000 for the rose gold model.
