Into the deep: Luminox Deep Dive 500

For a professional diving watch, it is critical and can even be the difference between life and death that the time is visible in any and all conditions, be it night diving, deep diving, diving in poor visibility or wreck diving. The Luminox Light Technology (LLT) ensures easy and immediate readability, and is always visible, constantly glowing for up to 25 years.

The tiny micro gas light glass tubes that guarantee constant visibility glow blue on the Deep Dive series, as blue is the last colour that the eyes register as one goes deeper and deeper under water. In addition, the Deep Dive features different colour of LLTs at the 12 O’clock position of the dial as well as on the rotating bezel, and since the minute hand is particularly important to divers, it is equipped with a double-LLT for easier reading, even in complete darkness. And because this model features an automatic mechanical movement with no battery required, the diver can always rely on the correct dive time when looking at his Luminox watch.

Why 500 Metres Water Resistance?

Many companies make watches with 200 metres water resistance, but 500 metres/50bar is much more challenging and as a result separates the Deep Dive Luminox from the pack. The sapphire crystal must be more than twice as thick as on a 200 metre watch (3.00 mm), as well as the caseback (3.00 mm). Steel deforms at 50 bar pressure, so the overall case construction has to be much more robust and rugged.

The new (or relatively new) automatic Deep Dive 500m is the latest addition to the Luminox collection of certified watches designed for diving professionals. It was launched towards the end of last year. The brand has been used for over 20 years by the Navy Seals, the U.S. Coast Guard, and Stan Waterman, a pioneer in the field.

American brand Luminox was founded in 1989 by watch industry professional Barry Cohen. He discovered a Swiss self-powered illumination system and immediately knew that it would make watches more visible and easier to read in low or no light situations.

Water-resistant to 500 metres, the easy to see 45mm Deep Dive features an automatic helium valve, a bezel locking system (patent pending), and the unique Luminox Light Technology system. This ensures optimum visibility thanks to the micro-tubes which emit a blue glow, the last colour a diver can discern as he descends. The Deep Dive comes in a numbered limited edition.
