Water & Dive
Purposeful watches with strong legibility and model-specific water resistance, including the famous Navy SEAL families.
Marcus Tempus
Bold without resorting to the usual all-black tactical look, the Luminox Pacific Diver Chronograph XS.3147 combines serious dive-watch capability with a rich Forest Green colour palette.
The 44mm black IP 316L stainless-steel case gives the watch a substantial, purposeful presence, complemented by a unidirectional CARBONOX™ bezel. Against the black case, the Forest Green dial and matching green nitrile rubber strap give this Pacific Diver a distinctive outdoors-inspired character.
The dial incorporates a full chronograph display and date, powered by the Swiss Ronda Z60 quartz calibre. Sapphire crystal with an anti-reflective coating protects the dial, while the screw-down crown and screw-in stainless-steel caseback contribute to an impressive 200 metres / 20 ATM water resistance.
Luminox Light Technology completes the package, providing continuous self-powered visibility for up to 25 years. It's a watch designed to move easily between diving, outdoor adventure and everyday wear — and that green gives it considerably more personality than the average tool watch.

Swiss Performance Watches
Performance on the Wrist
Luminox watches combine strong dial contrast, practical case construction and highly visible markers with a distinctly purposeful design language.
The result is a watch that feels equally at home outdoors, on the water or in everyday life — with the visual character to remain unmistakably Luminox.
The Technology
Luminox Light Technology uses tiny borosilicate glass capsules containing micro gas lights on the hands, hour markers and, on selected models, the bezel.
Unlike conventional luminous paint that must first absorb light, LLT is self-powered and designed to provide continuous visibility for up to 25 years.
A Defining Chapter
In 1992, Navy SEAL research and development officer Chief Nick North worked with Luminox to develop a watch suited to the demanding needs of the SEALs.
That collaboration helped establish the Original Navy SEAL 3000 Series and became one of the most recognisable parts of the Luminox story.
Purposeful Materials
CARBONOX™ is Luminox's carbon-based case material, developed for watches where low weight and robust construction matter.
Luminox describes CARBONOX™ as six times lighter than steel and three times lighter than titanium, while also being non-metallic, anti-magnetic and resistant to changing weather conditions.
The Luminox World
Purposeful watches with strong legibility and model-specific water resistance, including the famous Navy SEAL families.
Watches inspired by cockpit clarity, technical readability and the practical requirements of aviation.
Rugged watches designed for everyday adventure, field use and reliable visibility beyond the city.
Choosing Your Watch
Luminox collections include different case materials, movements, crystals, case sizes and levels of water resistance. Some models use quartz movements while others are automatic.
We therefore list the exact technical specification on each Marcus Tempus product page rather than applying one specification to the whole brand.
Care & Water Resistance
Water resistance is not permanent. Luminox recommends that gaskets are inspected and replaced every 18–24 months, or more frequently when a watch is regularly exposed to chlorinated pools or salt water. The exact water-resistance rating should always be checked on the individual model.
