Ulysse Nardin Diver X Skeleton

Ulysse Nardin's Diver X Skeleton, reference 3723-170LE-3A-BLUE/3B, is a titanium dive watch measuring 44 mm across. The case stands 15.7 mm thick and carries a unidirectional rotating bezel over a blue skeletonised dial. Inside is the self-winding calibre UN-372, with a silicon escapement, oversized oscillator and a 72 hour power reserve visible through the open construction. A sapphire crystal covers the dial. This piece belongs to a limited run of 175, one of the standout points alongside the openworked movement itself. Ulysse Nardin pairs the case with a rubber and titanium strap. The screw-down elements and case construction hold water resistance to 200 metres.
