Overview
Luminox Pacific Diver Automatic Watch with Black Dial.
The Pacific Diver line is named for the Pacific coast of California, where Luminox was founded in 1989. The Pacific Diver Automatic 3100 is the first automatic series of the collection, with a 316L stainless steel bezel set with a ceramic ring insert. The 316L stainless steel case measures 42 mm in diameter and 13 mm in thickness.
A Swiss Sellita SW 200-1 automatic movement, good for a 38-hour power reserve, powers the hours, minutes, seconds and date beneath an anti-reflective sapphire crystal. A screw-in crown and a 316L stainless steel case back close the case.
Textured with a wave pattern and carrying Super-LumiNova on the hour numerals, the black dial holds tritium gas tubes on the hands, hour markers and bezel, lit for up to 25 years. The watch is delivered on a black cut-to-fit rubber strap measuring 24 mm at the lugs, secured by a steel buckle.

Questions & Answers
How is the Pacific Diver collection divided?
Into standard three-hand watches in the 3120 and 3120M series, chronographs in the 3140 series and automatics in the 3100 series, all with a stainless steel case. Luminox was founded in 1989 by Barry Cohen and Richard Timbo, and assembles and tests its watches in Solothurn, Switzerland.
How does Luminox Light Technology work?
Each marker is a borosilicate glass capsule about 0.5 mm across, coated inside with phosphorescent powder and filled with tritium gas, so it glows around the clock with nothing to charge. Luminox holds the intensity constant for the first 10 years, after which the brightness decreases gradually as the gas loses energy, over a visible life of up to 25 years.
How long does it run when it is not worn?
Approximately 38 hours from a full wind. Daily wear keeps the mainspring wound, and a watch winder holds it at full power between wearings.
How well does the crystal hold up?
Sapphire sits at 9 on the Mohs scale, just below diamond, and Luminox gives it an anti-reflective coating for readability at any angle in bright light.
Who makes the movement?
Sellita, in La Chaux-de-Fonds, Switzerland. The watch carries the Swiss Made mark, which requires at least 60% of the manufacturing costs of the watch head to be incurred in Switzerland.
