Reactor Never Dark
is hands-down the best choice when you need high-performance
and reliable watch illumination:
Many designs and materials have been used over the years to illuminate watch faces in low light or darkness. Years ago, radium paint was applied to watch faces by hand, which proved hazardous to the workers and was eliminated. As an alternative compounds that produce luminous hands or markers without radiation have been used were developed, but the shortcoming of these materials is that they require exposure to light, and when placed in the dark after exposure to light, they phosphoresce for only a few hours in the dark. Electroluminescence was introduced in the '80s, but has the disadvantages of reducing battery life and requiring a button press to activate. A major advance in the 90's was the introduction of tritium-filled luminous tubes. The tubes glow for years without any exposure to light, which makes them a durable choice. The disadvantage of tritium tubes is that their brightness is relatively low and can be ineffective in partially light conditions or when you eyes are in the process of adjusting to darkness, which is actually a gradual process and takes some time when moving from light to dark. While tritium tubes will glow for years, their relatively low brightness can be difficult to see in partially lit conditions, or immediately after moving from a brightly lit to a dark environment. Starting in 2003, Reactor developed a proprietary method of applying a unique Swiss material called Superluminova that makes their watches the brightest and longest-lasting phosphourescent watches in the world (they had them independently tested to prove it). However, while Superluminova is at least five times brighter than tritium after being charged in the light, that brightness fades to below that of tritium over several hours, so Reactor went the extra step and combined it with Tritium.
Never Dark™ is the first technology to combine the intense brightness of Superluminova with the multi-year longevity of tritium, providing optimal illumination under all lighting conditions. Because it can take up to 30 minutes for the human eye to fully adjust to the dark, Superluminova's intense peak brightness makes a Never Dark™ watch easily visible during that initial period. This can be even more important when moving repeatedly from light to dark (such as when going below deck on a boat during the day), as the Superluminova will continually recharge and the eye will not have time to adjust. In situations where the watch will remain in the dark for many hours, the tritium will remain visible for years, even if the watch is never returned to the light.
This graph illustrates the performance of each illumination source over time. While tritium remains at a constant level, Superluminova gets extremely bright then fades over several hours, but recharges very quickly when re-exposed to light. Never Dark™ is the only watch illumination to "self-adjust" to conditions, with a response curve similar to that of the human eye. At its peak, the glow of Superluminova is easily visible, even at dusk or in difficult, partially lit conditions. With a full charge, it produces five to ten times the light output of tritium. But, as that brightness fades, the tritium will continue to glow for at least ten years. Tritium is radioactive. Should You be worried? Take a look at the Reactor Trident with Never Dark

 Shop for Reactor Trident, the Never Dark Watch
Iraq Platoon loves their Reactor Tridents A scout sniper platoon deployed in Iraq was having durability and reliability problems with their current watches. They tried Reactor Trident and were very impressed. "My Scouts have been wearing them for 2 months now, and have not had a single problem. This may be a normal thing to you, but for us to have equipment that refuses to break is unheard of." said the Platoon Leader.
