Inner beauty revealed
An X-Ray vision of next generation Haute Horlogerie.
Features
The case of each Ulysse Nardin timepiece is individually numbered on the side.
Skeleton X plays off the transparency of its powerful movement, to reveal the stunning beauty of the three-dimensional heart beating inside.
Skeleton X is presented on an alligator leather strap with a titanium pin buckle.

"Traditionally are skeleton watches dominated by their movement for obvious reasons, but Ulysse Nardin has found a way to unite this aspect with an equally enticing case. More so, their design even incorporates a skeletonized dial, that hides hardly anything but does add a nice dose of functionality to the mix."
