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
