Luminox Carbon SEAL Automatic 3875 Red Strap Dive Watch 45mm 200m

Carbonox Dive Watch 45 mm 200 m

The Luminox Carbon SEAL Automatic 3875 is a men's diver's watch built around a 45 mm Carbonox case with a unidirectional rotating bezel, screw-down crown and screw-on steel caseback. A Swiss-made automatic movement drives a black analog dial with index markers and a day-date window, all protected by sapphire crystal with anti-reflection coating. The red rubber strap uses a buckle clasp and is adjustable to fit.

Self-Luminescent Swiss Diver for Daily Wear

This watch suits buyers who want constant low-light readability from tritium gas tubes on the hands and markers without charging from an external light source. The 200 m water rating covers recreational diving and heavy water exposure. Buyers who need a helium-escape valve for saturation diving or a lighter titanium case should look elsewhere.

Tritium Night-Visibility Tubes

The defining specification is the self-powered tritium illumination system on hands and markers, which glows continuously for years without batteries or light charging. This feature decides whether the watch meets a buyer's requirement for instant legibility in total darkness.
