Ulysse Nardin Diver Net OPS 44 mm – Ref. 1183-170-8A/3A
Bold yet sustainable, the Ulysse Nardin Diver Net OPS (Ref. 1183-170-8A/3A) blends eco-focused materials with robust dive functionality. With a limited production around 2024–25, this 44 mm timepiece positions itself at the intersection of avant-garde sportswear and high-end watchmaking.
Case: Recycled Steel Advanced Composites
The 44 mm case uses a core of 95 % recycled stainless steel, with flanks and caseback made of Nylo® composite—a polyamide derived from recycled fishing nets—and accents of Carbonium® carbon fiber. This combination delivers both durability and lightweight comfort, all while supporting Ulysse Nardin’s sustainability mission. The watch remains water-resistant to 300 m (30 ATM) and measures 14.81 mm thick.
Dial Readability: Bold Functional
The sandblasted khaki green dial features a large satin-finished “X”, power reserve indicator at 12 o’clock, and small seconds subdial with integrated date at 6 o’clock. Beige Super-LumiNova-coated indices and hands emit a green glow in low-light settings, ensuring optimal legibility during dives or deep-sea adventures.
Reliable Movement: UN‑118 Automatic
Powering the 1183-170-8A/3A is the in-house UN‑118 automatic movement, delivering a reliable 60‑hour power reserve. It features Ulysse Nardin’s signature DiamonSIL-coated escapement and silicon balance spring—offering superior accuracy and magnetic resistance.
Straps: Rugged Versatility
Available with two strap options:
- A rubber strap in khaki green with a ceramic element stamped “Ulysse Nardin” — rugged and sporty.
- An alternative fabric strap (also khaki green), woven with recycled fishing-net fibers, offering lightweight performance and quick-dry wearability.
Both options feature secure closures suited to aquatic or active use.
