Ulysse Nardin Diver Chronograph

Ulysse Nardin's Diver Chronograph, reference 1503-170-3/93, has a titanium case measuring 44 mm across. The case stands 16.1 mm thick and pairs with a blue dial. A self-winding calibre UN-150 drives the watch, with 48 hours of power reserve and a DIAMonSIL escapement. The dial sits under a sapphire crystal. As a chronograph, it carries a central chronograph display, small seconds at 9 o'clock and a date window between 4 and 5 o'clock. Ulysse Nardin fits it on a rubber and titanium strap. The case is rated to 300 metres, well suited to the diving and sailing use the model was built for.
