Ulysse Nardin Blast Skeleton X

Ulysse Nardin's Blast Skeleton X, reference 3715-260/CARB, has a 43 mm case in Carbonium and gold. The case measures 10.65 mm thick, with a sapphire crystal over the dial. The manual-winding calibre UN-371 drives the watch, offering 96 hours of power reserve from within a fully skeletonised architecture that exposes the gear train and escapement. This openworked construction is the watch's defining complication, with the movement's bridges and mainplate cut away rather than hidden beneath a solid dial. A calf leather strap fits the case. Water resistance stands at 50 metres, modest for a piece built around display rather than depth.
