Key features of the Reactor Gamma include a 10-year power supply, 300M depth rating and an anti-reflective coated crystal for easy viewing under water. The massive case, solid steel construction and screw-bar band to case attachment make this the perfect watch for extreme sportsmen. . . . . Brushed Finished Case and Bracelet with Polished Accents . . Unidirectional Rotating Bezel . . Solid, Forged Titanium Case . . Solid Screwbar to Case Attachment; This system is nearly 8 times stronger than the typical springbars typically used in watch construction. With this system you won’t have to worry about losing your watch due to the band detatching from the case. . . Extra Thick Hardened Mineral Glass Lens; This K1-Hardened Mineral Crystal combines exceptional scratch resistance with unmatched shatter resistance. . . Triple O-Ring Screw Down Crown System; Extremely water resistant Triple O-Ring system not only provides extra protection when the crown is screwed in, but also provides protection to 100 Meters (330 Feet) if you happen to forget to screw the crown back in after setting your watch before getting in the water! . . Superluminova on Hands and Markers; The Swiss made Superluminova goes through a special application process to make these watches extremely visible when in a low lit area and will provide exceptional visibility for up to 8 Hours. . . Shock Resistant Movement Holder; A special casing helps to protect the already Shock Resistant Japanese Quartz Movement from severe impacts. . . Square Profile Caseback Seal; Having more surface area than the typical O-Ring seal, this provides a significantly superior water-tight seal. . . Over-Sized Screw Down Crown; Large size makes it easy to grip, un-screw and set the date and time with ease . . Comes encapsulated in a protective standing metal case and is revealed by rotating the outer case half. . . Black Rubber Strap . . 10 Year Lithium Power Supply . . Water Resistant to 300 Meters (990 Feet) with the CrowWith its bold black dial and sporty style, the Men’s Gamma Round Black Dial Rubber Strap Watch from REACTOR looks rugged and casual, yet is also polished and versatile enough for work. Titanium construction ensures durability, and combines with a screw-down crown, luminous Superluminova painted hands and markers for easy readability, a unidirectional bezel that’s great for workouts, and day and date functions to keep you organized. A black rubber strap completes the modern look, and closes with a sturdy buckle clasp. Water resistant to an impressive 984 feet, this REACTOR original arrives in a distinctive silver box that’s ideal for storage or gift-giving.

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.
