The Ulysse Nardin Diver [Hammerhead Shark], reference 1183-170LE-3A-HAMMER/0A, is a commanding expression of aquatic expertise and conservation-focused design.

Blue PVD Titanium Case with 300 m Water Resistance

Encased in robust 44 mm blue PVD-coated titanium, this Diver blends lightweight durability with deep-sea practicality. The uni-directional bezel features a rubber insert and sapphire crystal, ensuring reliable 300 m water resistance and underwater functionality. Refined red crown protectors reinforce the strong marine aesthetic.

Hammerhead Dial & Functional Design

The sandblasted blue dial showcases the signature Diver “X” motif, illuminated by Super-LumiNova indices. A small-seconds subdial at 6 o’clock hides a date aperture, adding function without disrupting symmetry. Hints of red bring the hammerhead motif subtly to life.

UN‑118 Movement – High-Tech Powerhouse

Powered by Ulysse Nardin’s in-house Calibre UN‑118, this automatic movement features a silicon escapement and anti-magnetic DiamonSIL technology. Beating at 4 Hz, it provides a resilient 60-hour power reserve. Tools-free via the screw-down crown, this mechanism delivers precision and durability in one titanium lightweight case.

Fabric Strap with Velcro Fastener

Diverging from its rubber sibling, the1183-170LE-3A-HAMMER/0A model includes a blue textile strap edged in red, secured with a Velcro-style fastener. This rugged yet sporty strap is designed for secure wear in extreme conditions, sporting a trimmed aesthetic that echoes the watch’s hammerhead theme.
