"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."
