Ulysse Nardin Diver X Skeleton

Ulysse Nardin's Diver X Skeleton, reference 3723-170LE-2A-BLACK/3B, is a 44 mm titanium case with black PVD treatment. The case measures 15.7 mm thick and carries a unidirectional rotating bezel. A sapphire crystal covers the skeletonized dial, which lays bare the manufacture movement beneath. The self-winding calibre UN-372 has 23 jewels and delivers 72 hours of power reserve, its oscillator and escapement built in silicon. This is a limited edition of 175 pieces, black in colour throughout. The strap combines rubber and ceramic with a fabric section. Water resistance reaches 200 metres, solid enough for genuine diving use.
