Luminox is derived from latin, with ‘Lumi’ meaning light, and ‘Nox’ meaning night. Luminox watches have built for themselves a reputation among professionals from the Navy SEALs all the way to pilots, and many of the armed forces in the world. Luminox got its big break when Nick North came to a trading show to procure a series of watches so that The SEALs could perform better during night missions. When he came across the Luminox ‘Always Visible’ technology he was thoroughly impressed and over the next two years worked with Luminox to perfect the iconic Navy SEALs watch.
Luminox’s Always Visible technology works from gas filled boro-silicate tubes where tritium gas is constantly illuminating the watch. During favorable lighting conditions there is no noticeable glow; however, as soon as the light quality diminishes the intense glow of the Luminox technology is apparent. There is no need to charge the lume with a light source making this one of the more convenient options for professionals. The tritium gas is guaranteed to continually glow for an impressive 25 years.
The A.1513 comes from their diving class and is crafted from finely brushed stainless steel which adds a rugged look to this piece. The case diameter comes in at 44mm which is a great size for most men. The blue ion plated bezel features an elapsed time diving scale which is in silver tone making for excellent contrast. Naturally, the bezel is unidirectional allowing for this watch to safely display the elapsed time when on a diving mission. The main crown is screw locked which maintains the water resistance on this watch at a superlative 500 meters (1650 feet). The ridged main crown is also protected by a latch style crown guard against impacts.
One of the more impressive features on this watch is the helium release valve. When diving, helium gas starts to build up inside the watch. If left unchecked, the gas has the potential to cause irreversible damage to your timepiece. The valve used here is an automatic valve which consistently makes sure the pressure inside the A.1513 is maintained at a safe level.
The dial on this model is blue and carries indexes with the sole exception of the 3 position which carries the date display. Driving this watch is an automatic Swiss made movement. The Luminox A.1513 is secured by a blue striated rubber strap fitted with a classic ardillon buckle.
