With this Diver Deep Dive, Ulysse Nardin gives us a professional diving instrument complete with titanium crown-guard, helium escape valve and water-resistance to 1,000 metres. Another new feature, the rubber strap has an expandable element that adjusts to changes in wrist size caused by the compression of a neoprene diving suit. The robust, angular-shaped case is in titanium with cut-edged horns, while 12 notches around the wide bezel ensure easy manipulation, even with diving gloves.
