Purposeful watches with strong legibility and model-specific water resistance, including the famous Navy SEAL families.

Product Story
Inspired by the dramatic landscape of Chile's Atacama Desert, the Luminox Atacama Field XL.1971.2 combines classic field-watch design with lightweight modern construction and Luminox's signature self-powered illumination.
The standout feature is its warm grey, sand-textured dial, paired with bold black Arabic numerals and a secondary 24-hour scale for clear, intuitive reading. A red-tipped seconds hand and small red arrow beside the date at 3 o'clock introduce subtle colour while reinforcing the practical field-watch character of the design.
The 43mm CARBONOX™ case is exceptionally light and durable, while an anti-reflective sapphire crystal protects the dial. Inside is the dependable Swiss Ronda 515 quartz movement, providing straightforward time and date functionality.
Luminox Light Technology provides continuous self-powered visibility for up to 25 years, without requiring external charging or the press of a button. With 100 metres water resistance and a total weight of only 66g, the XL.1971.2 is designed to move easily between everyday wear and outdoor adventure.

Made to Be Read at a Glance
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
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
The Navy SEAL Connection
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™
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
Sea. Air. Land.
Aviation Influence
Watches inspired by cockpit clarity, technical readability and the practical requirements of aviation.
Outdoor Performance
Rugged watches designed for everyday adventure, field use and reliable visibility beyond the city.
Choosing Your Watch
Specifications Vary by Model
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
Keeping a Luminox Ready for Use
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.
