While every Reactor is made for use in and around water, the Poseidon takes the concept to the extreme. This professional diver model features a 1000M depth rating and dual internal/external rotating timing bezels to keep track of bottom time and safety stops. Also available in a limited edition model with Never Dark® technology and dual interchangeable bands.
Never Dark®- The World's Most Advanced Watch Illumination
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.

The Reactor DNA
Reactor claim to be the Best Built Performance Sport Watch isn't just marketing hype. Reactor was conceived from day one to design out any weakness and improve any feature possible. The result of this "genetic engineering" is the Reactor DNA, a set of features that is shared by every Reactor Watch. This DNA forms the core of a product that will outlast and outperform every other watch you have ever owned.
Solid Forged Cases
Forging produces a stronger part, and we forge all our cases from either titanium or type 316L marine-grade stainless steel for the ultimate in corrosion resistance and longevity.
Springbars are the weak point of most watches, so we eliminated them entirely. All our bands attach via a solid, threaded screwbar, providing at least a 500% increase in strength.
Every Reactor uses a unique screw down crown system that maintains water resistance when unscrewed, and every crown is protected by crown guards integral to the case, eliminating the most common causes of water intrusion.
For superior low light visibility, we use this unique Swiss material on all our dial markings and hands. Our exclusive application method makes our watches the brightest in the world.
Like fine Swiss watches, every Reactor features a caseback forged from the same material as the case. This provides a rigid, watertight seal, even after a battery replacement.
