Another solid diving watch from the experts of the genre. Some extra predator’s charisma included.
Ulysse Nardin Diver Chronograph Hammerhead Ref.1502-170-3/93
Ulysse Nardin has quite a tradition in making diving watches, and all three versions of the new Diver Chronograph Hammerhead Shark stick to it rather faithfully. Whether it’s a bulky 44-mm case water-resistant up to 300 meters, a massive uni-directional bezel, broad hands and indices covered with lume, or screw-down crown and pushers – you’ve definitely seen them all before. However these familiar design codes are time-proven and seem to perfectly work together. The same goes to the symmetrical dial-layout featuring three central hands, 30-minute counter at 3, small seconds at 9, and a 12-hour counter with a date window at 6.

The watch is available in titanium with black dial, in rose gold with blue dial, and in titanium with blue dial and tons of red accents. The latter is a limited edition of 300 pieces, and unlike the first two, it’s fitted with a solid caseback instead of the sapphire crystal providing the movement view. Further emphasizing the overall tool-vibe of the Diver Chronograph Hammerhead Shark the guys at Ulysse Nardin gave the limited edition a nice hammerhead shark engraving. Beating inside is the UN-150 automatic in-house movement with a silicon escapement and 48 hours of power reserve. Strap options include a rubber strap, a metal bracelet or a fabric strap with closing scratch.
