Wrist Watches A+

This striking men's watch from Reactor features high-quality craftsmanship with deluxe materials for both long-lasting durability and bold style. The striking blue dial offers a gorgeous contrast to the white, patented Superluminova-finished numerals and hands, which offer up to eight hours of low-light readability. The indexes, with their stylishly modern, oversized design, are easy to read, as is the handy day and date calendar located at the three o'clock position. A tachymeter forms the outer perimeter of the dial; the unidirectional bezel provides a very stylish touch as well as additional timekeeping functionality. The watch's 40-millimeter case is constructed of sold, marine-grade 316L stainless steel for ultimate corrosion resistance, and the hardened mineral glass crystal offers extreme scratch and shatter resistance. The handsome stainless steel wrist band includes a fold-over clasp with a safety lock for additional security. Like all Reactor watches, each Critical Mass watch is individually tested to its depth rating of 200 meters. The watch is powered by analog quartz movement.

In a sleek black nitride, the Trident from Reactor is hip enough for contemporary dress and durable enough for daily wear. The 40-millimeter case frames the unidirectional bezel, and attaches to the linked bracelet with a sturdy screw bar. In combination with constant illumination from innovative Never Dark technology, the black dial also features Superluminova hands and indexes, large Arabic numbers and a day/date display at three o'clock. Water resistant to 660 feet, the stylish Trident helps casual wear look smart and trendy.Reactor Never Dark™ - the World's Most Advanced Watch Lighting SystemThroughout 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.

The new Titanium models in Reactor's Gamma line are sure to be extremely popular. With a lighter, strong metal construction these watches are even more durable for those who love extreme sports or just require a watch that can survive almost anything... . . . . Brushed Finished Case and Bracelet with Polished Accents . . Black dial with Day and Date at the 3 o'clock position . . Unidirectional Rotating Bezel . . Titanium construction - stronger and lighter than stainless steel. . . 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. . .

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 SystemThroughout the history of the wristwatch, designers have struggled with the best method to illuminate the watch face for easy viewing at night.
