Ulysse Nardin Blast Skeleton X

Ulysse Nardin's Blast Skeleton X, reference 3716-260B/02, comes in an 18 ct rose gold case measuring 42 mm across. The case stands 10.65 mm thick and holds a fully skeletonised dial that lays the movement open to view. Manual-winding calibre UN-371 drives the watch, offering 96 hours of power reserve, with hours and minutes as the only functions on display. A sapphire crystal covers the dial, leaving the openworked bridges and mainplate visible from the front. The rose gold case is paired with an alligator leather strap. This is a watch built around its architecture rather than added complications, with skeletonisation as its defining feature. Water resistance is rated to 50 metres, modest but consistent with a dress piece of this kind.
