REACTOR Men’s 52001 Gamma Never Dark Titanium Watch with Link Bracelet
Reactor’s #1 selling watch gets an update for 2010 with solid titanium construction and their exclusive Never Dark® illumination system. Reactor’s latest creation will quickly become the choice in watches for the serious outdoorsman as well as elite tactical units.It is easy to see why Gamma is Reactor’s best selling watch. Its 45.5mm dia. case, 10-year power supply, 300M depth rating and anti-reflective coated crystal make it the ultimate water sport watch.Boasting titanium construction for long life and a sleek, sporty look, the Men’s Gamma Round Stainless Steel Watch from REACTOR combines the reliability of Japanese quartz movement with a streamlined, athletic-inspired design. An extra-thick mineral crystal resists both scratches and shattering, while solid screwbar case-to-band attachment, and solid forged casebacks guard against longterm wear and tear. For added convenience, luminous Superluminova painted hands and markers on a black dial ensure easy readability, a unidirectional bezel is great for workouts, and day and date functions at three o’clock keep things organized. Water resistant to an impressive 984 feet, the Gamma is perfect for work or dress wear, yet rugged enough for weekend adventures.
Reactor Never Dark™ – the World’s Most Advanced Watch Lighting System
Throughout the history of the wristwatch, designers have struggled with the best method to illuminate the watch face for easy viewing at night. Originally, radium paint was applied, but the radioactive side effects to the workers quickly made this unacceptable. Various phosphourescent compounds have been tried, but most remain visible only a short while in the dark. Electroluminescence was introduced in the ’80s, but has the disadvantages of reducing battery life and requiring a button press to activate. Tritium-filled luminous tubes entered the market in the ’90s, and while their multi-year illumination makes them a good choice, 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 our watches the brightest and longest-lasting phosphourescent watches in the world (as verified by independent testing). 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. As part of our quest to build the best watch possible, we saw a better solution.
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?
Unlike radioactive isotopes that have been used on watches in the past, tritium poses no health risk to the wearer or to the workers who assemble the watches. Tritium’s radioactive decay produces only weak beta particles that are contained completely within the sealed glass tubes. Even if exposed, the beta particles do not posess enough energy to penetrate the outer layer of human skin.
