When fine watchmaking plunge into the world of diver watches

A sporty appeal, while taking a radical step towards transparency Diver X Skeleton is an explosive fusion between the sporty design of a Diver and technical prowess of the Executive Skeleton. It’s a match that was written in the stars.


The case, microbeaded on the sides with satin polished lugs, are coated in blue PVD. Orange details add vibrant pops of colour and emphasize the model’s sports origins.

The hour markers of Diver X Skeleton have to be secretly connected to the dial, so they appear to be floating. To achieve the sensation of depth, overlaid layers are used to emphasize the tiered construction of the central “X”. Different levels of finish were also employed to cause a play of light, which was amplified by the transparency of the skeleton movement.

Diver X Skeleton comes on a rubber strap in supercharged orange with an element adorned with the Ulysse Nardin anchor in orange.


"In an exciting fusion that unites the Diver and Executive Skeleton collections, Ulysse Nardin adds a new gem to its range of UFO timepieces, reinterpreted with X-ray vision: the Diver X Skeleton, an exclusive edition of skeletonised diving watches limited to 175 numbered pieces."
