Ulysse Nardin Diver AIR

Ulysse Nardin's Diver AIR, reference 3743-170-2A/0A, has a 44 mm case built from titanium, nylon and carbon fibre. The case measures 14.76 mm thick, keeping the watch light on the wrist despite its size. A unidirectional rotating bezel surrounds the black dial, which sits under a sapphire crystal. The self-winding calibre UN-374 drives the watch and stores 90 hours of power reserve, with the skeletonised construction leaving the movement visible from the front. Silicon components make up the escapement wheel, anchor and balance spring. An elastic fabric strap with a scratch closure fastens the watch to the wrist. Ulysse Nardin rates the case to 200 metres.
