Ulysse Nardin Diver Chronograph

Ulysse Nardin's Diver Chronograph, reference 1503-170-3/92, has a titanium case measuring 44 mm across. The case stands 16.1 mm thick and carries a sapphire crystal over a black dial. Inside is the self-winding calibre UN-150, with 48 hours of power reserve. This chronograph combines a date function with small seconds at nine o'clock, plus the standard chronograph registers for thirty minutes and twelve hours. The strap is rubber with titanium elements, suited to the watch's diving intent. Titanium keeps the weight down without sacrificing durability. Ulysse Nardin rates the case to 300 metres, in keeping with its purpose as a companion for time spent at sea.
