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.

Questions about this item

What is the 45 mm case diameter and 200 m water resistance rating for fit and dive use?

The carbon case measures 45 mm across and is rated to 200 m (660 ft), making it suitable for professional diving and daily wear.

How do I set the automatic movement and day/date correctly without damaging the screw-down crown?

Unscrew the crown counter-clockwise, pull to the first position for date, second for day and time, then push and screw it back down firmly to maintain water resistance.

When should the sapphire crystal, Carbonox case seal or rubber strap be inspected or replaced?

Have the crown and caseback seals pressure-tested every two years; replace the rubber strap if it shows cracking or loss of elasticity.
