Ulysse Nardin Diver [Hammerhead Shark] 44 mm – Reference 1183-170LE-3A-HAMMER/0A

The Ulysse Nardin Diver [Hammerhead Shark], reference 1183-170LE-3A-HAMMER/0A, is a commanding expression of aquatic expertise and conservation-focused design. Rich with dive-ready features and limited to just 300 pieces, this edition pairs rugged performance with bold style—enhanced by a blue-and-red fabric strap with Velcro fastener, distinguishing it from the rubber-strapped variant.

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.
