NH35A-620C633

Case
Engineered for the most extreme environments — from deep-sea diving to space exploration.
The watch features a robust 49 mm stainless steel case with a professional diver’s bezel, offering water resistance up to 30 bar (300 m) for unmatched durability in the harshest conditions.

The case also integrates an automatic helium release valve — a spring-loaded, one-way system that activates under critical pressure differentials, making it the ideal companion for professional divers operating in mixed-gas environments.

Dial
The multi-layer dial is protected by a hardened 3.5 mm K1 crystal, ensuring superior strength and clarity. Equipped with 13 Swiss-made tritium tubes mounted vertically on the dial and 2 in the hands, it guarantees exceptional low-light readability.
Tritium illumination requires no charging, is completely maintenance-free, and ensures continuous luminosity for at least 10 years.

AccessoriesDelivered with two interchangeable straps — silicone and genuine leather — both designed for easy switching with the included screwdriver.
Packaged in a rugged VE DryBox L, a waterproof and shock-resistant case engineered to protect the watch or other valuables during extreme activities.
