Product Story

Inspired by the strength and texture of mountainous landscapes, the Luminox Pacific Diver Chronograph XS.3148 takes the capable Pacific Diver platform and gives it a sophisticated monochrome treatment.

The substantial 44mm black IP stainless-steel case is paired with a unidirectional CARBONOX™ bezel, while the Graphite Grey details and matching rubber strap create a layered palette of black, charcoal and grey. The result is unmistakably rugged, but more understated than many traditional military-inspired Luminox designs.

At its heart is the Swiss Ronda Z60 quartz chronograph movement, providing chronograph and date functions. Sapphire crystal with anti-reflective coating protects the dial, while a screw-down crown, secured stainless-steel caseback and 200 metres of water resistance make it equally suited to demanding outdoor use and life around the water.

Luminox Light Technology provides continuous self-powered illumination for up to 25 years, completing a versatile Swiss Made chronograph designed to perform across land and sea.

Performance on the Wrist

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 illuminated dial detail

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™

Luminox watch with CARBONOX case

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.

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.
