Ulysse Nardin introduces the Diver [Hammerhead Shark], a 44mm blue PVD-coated titanium dive watch that blends high-performance horology with marine advocacy.

Continuing the Maison’s historic ties to the sea—rooted in its 1846 origins and marine chronometer legacy—this edition honors the Hammerhead, an elegant yet critically endangered predator threatened by overfishing and climate change. As part of Ulysse Nardin’s SHARK series, 1% of annual sales support marine conservation through the 1% for the Planet initiative, with proceeds benefiting the UK-based Shark Trust.

The campaign is championed by ambassador Mike Coots, a shark-attack survivor turned preservation advocate.

Technically robust, the watch houses the in-house UN-118 calibre with antimagnetic, lubrication-free silicon components, a 60-hour power reserve, uni-directional bezel, running seconds, and 300-metre water resistance, plus a convenient date corrector at 6 o’clock. More than a dive instrument, the Diver [Hammerhead Shark] stands as a bold reminder that craftsmanship can serve both precision and purpose.
