Ulysse Nardin Diver X Skeleton OPS

The Ulysse Nardin Diver X Skeleton OPS, reference 3723-170-2C/3A, is a 44 mm dive watch built from Carbonium and black PVD titanium. The case measures 15.7 mm thick and carries a unidirectional rotating bezel. A sapphire crystal covers the black skeletonised dial, which exposes the self-winding calibre UN-372. This manufacture movement runs on a silicon escapement with an oversized oscillator and nickel flyweights, and it stores 72 hours of power reserve. The layout is limited to hours, minutes and seconds, leaving the open construction to do the talking. A rubber and ceramic strap closes the piece. Water resistance reaches 200 metres.
