Ulysse Nardin Diver X Skeleton “One More Wave” 44 mm – Ref. 3723-170LE-2A-OMW/3A

The Ulysse Nardin Diver X Skeleton “One More Wave”, reference 3723-170LE-2A-OMW/3A, is a bold, purpose-driven diver’s watch blending avant-garde design, sustainable materials, and impactful storytelling. This 44 mm creation pays tribute to ocean conservation and veteran welfare through its collaboration with the U.S. non-profit One More Wave, delivering haute horlogerie with a conscience. Limited to just 50 pieces globally, this Diver X stands as both a collectible and a catalyst for positive change.

Eco-Conscious Construction & Technical Rigour

Housed in a robust case crafted from black DLC-coated titanium with a unidirectional bezel in recycled Carbonium®, the watch is water-resistant to 200 m and built for demanding aquatic environments. This cutting-edge material choice not only reduces environmental impact, but also provides extraordinary strength and lightweight comfort—ideal for deep-water or eco-conscious explorers.

Skeletonized Visibility & “X” Motif

The matte-black skeleton dial boldly reveals the UN‑372 automatic movement, featuring a central “X” motif inspired by maritime signal flags. Turquoise Super-LumiNova accents atop the dial, hands, and bezel echo the One More Wave logo and provide exceptional legibility in low light. This interplay of materials and design reveals both form and function in perfect balance.

UN‑372 Movement: Silicon-Powered Precision

The in-house UN‑372 caliber incorporates cutting-edge silicon architecture, including balance wheel, hairspring, escapement, and anchor. Running at 4 Hz with a 72‑hour power reserve, it delivers skeletonized chronometric performance while visible through the sapphire caseback.

Meaningful Mission & Limited Edition Impact

Part of a limited run of 50 pieces exclusively for the U.S., the Diver X Skeleton “One More Wave” advances Ulysse Nardin’s ethos of meaningful partnerships. A portion of proceeds supports surf therapy programs for U.S. veterans living with PTSD and disabilities—a powerful statement that extends beyond horology.

Strap & Ergonomics

Paired with a durable grey rubber strap featuring black ceramic and titanium elements on the deployant clasp, the 3723-170LE-2A-OMW/3A offers balanced comfort and sturdiness. Every component, from strap to clasp, reflects the rugged, mission-ready character of the design.
