Ulysse Nardin Diver X Skeleton

Ulysse Nardin's Diver X Skeleton, reference 3723-170LE-3A-BLUE/3A, is a titanium dive watch measuring 44 mm across. The case stands 15.7 mm thick and pairs with a unidirectional rotating bezel for tracking elapsed time. A sapphire crystal covers the blue skeletonised dial, which exposes the self-winding UN-372 calibre with its silicon escapement and oversized oscillator. Power reserve runs to 72 hours. This limited edition is capped at 175 pieces, and the openworked construction lets the finishing of the movement show through from both sides. The watch fits a rubber and titanium strap. Water resistance is rated to 200 metres, generous for a piece built around such an open dial.
