Ulysse Nardin Diver Chronometer “One More Wave” – Ref. 1183-170LE-2A-OMW/3A

A tribute to valor and ocean therapy, the Ulysse Nardin Diver Chronometer “One More Wave” (Ref. 1183-170LE-2A-OMW/3A) is a limited-edition 44 mm automatic diver watch created in collaboration with the One More Wave nonprofit. Limited to just 100 pieces worldwide, this model supports U.S. veterans with surf therapy initiatives and reflects Ulysse Nardin’s enduring nautical heritage.

Black DLC‑Coated Titanium Case

The lightweight 44 mm case is crafted from sandblasted and satin-finished black DLC titanium, offering exceptional corrosion resistance and rugged style. At approximately 14.8 mm thick and 50 mm lug‑to‑lug, it balances wrist presence with wearability. The domed sapphire crystal and concave bezel enhance dive utility while maintaining a refined profile.

Function‑Driven Black Dial

The matte black dial presents a clean, legible layout optimized for underwater readability. It includes a prominent power reserve indicator below 12 o’clock, and a small‑seconds subdial with integrated date at 6 o’clock. Baton indices and broad hands are treated with luminous material to ensure visibility in low-light ocean conditions.

Calibre UN‑118 Automatic Movement

Powering the 1183-170LE-2A-OMW/3A is the in-house UN‑118 automatic caliber, offering a reliable 60-hour power reserve and operating at 4 Hz. Featuring Ulysse Nardin’s precision technology— including a DiamonSIL-coated escapement and silicon hairspring—this COSC-grade movement delivers excellent accuracy and magnetic resistance. The rotor is branded with the symbolic anchor medallion.

300‑Meter Dive Capability

Built to meet professional dive standards, this watch is rated to 300 m (30 ATM). It features a screw-down crown and solid case architecture to ensure water resistance. Whether navigating surf therapy or exploring underwater terrain, it delivers reliable performance in demanding conditions.

Grey Rubber Strap with Ceramic Accents

The /3A version includes a grey rubber strap fitted with ceramic-studded pin buckle and branded Ulysse Nardin clasp. The strap ensures comfort, flexibility, and durability in aquatic environments, completing the rugged yet refined ethos of this limited edition.

Limited Edition Humanitarian Mission
