Ulysse Nardin 8163-175LE/92-LEMONSHARK Diver Lemon Shark 42mm Black Dial Watch

Ulysse Nardin Diver “Lemon Shark” – Ref. 8163-175LE/92-LEMONSHARK

The Ulysse Nardin Diver “Lemon Shark” (Ref. 8163-175LE/92-LEMONSHARK) is an ocean‑bound limited edition — just 300 pieces worldwide — created to support shark conservation and marine research. With a rugged 42 mm black DLC‑coated steel case, the Lemon Shark offers bold style, sustainable components, and uncompromising dive capabilities.

Case Coating: Dark Durable

Its 42 mm case is constructed from stainless steel with a full matte black DLC coating that suppresses glare and enhances endurance. The screw‑down crown and domed sapphire crystal ensure a robust 300 m (30 ATM) water resistance, ideal for serious diving. Engraved on the solid caseback is a detailed shark motif as a nod to the sustainable mission behind the piece.

Dial Design: Shark‑Themed Accents

Beneath the crystal lies a finely sand‑blasted black dial punctuated by neon‑green highlights — seen on the tip of the seconds hand, the “0” marker on the bezel, and the UN logo at 6 o’clock. Baton indices and hands are treated with “shark‑grey” Super‑LumiNova for high legibility underwater. The date window at 6 o’clock integrates harmoniously into the layout.

Movement: Caliber UN‑816 Automatic

Driving the Diver is the in‑house UN‑816 automatic caliber — based on a modified Sellita SW‑300, upgraded with silicon escapement components and anchor system for long‑term precision. Beating at 4 Hz, it delivers approximately 42 hours of power reserve — enough reliability for both deep-sea use and daily wear.

Strap: Ocean‑Friendly Style

The 8163-175LE/92-LEMONSHARK edition comes fitted with a black textile R‑STRAP made from recycled fishing nets collected in France. The secure Velcro-style closure attaches to blackened titanium hardware and includes a touch of neon green stitching to echo the dial’s accents — a perfect blend of sustainability and sportiness.

Limited Edition Conservation Impact

Produced in just 300 numbered units, the Lemon Shark edition was launched in conjunction with World Ocean Day. It partners with marine organizations such as OCEARCH and FIU’s Aquarius program to promote shark research and ocean health—embedding purpose within the design.
