Atom – The First Mid-Sized Reactor Watch with Never Dark Illumination

Reactor78901MidReactor prides themselves on having some of the most durable, well made watches on the market as well as excellent customer service. With the Reactor DNA, each watch is guaranteed to have superior water resistance, solid strap to case attachment, high quality Swiss Superluminova, and marine grade stainless steel for excellent strength and corrosion resistance. Their Never Dark illumination system features a combination of Tritium and Superluminova for legibility in any light. However, this has not been a feature you could find on their mid-sized (or ladies’) models until now.

Reactor78091 The Atom Mid-Size model 78091 is the first watch available from Reactor in a smaller size featuring their signature Never Dark technology. Sized for women, it has a classic black dial, day and date display and bright red second hand. The bracelet is solid stainless steel and has a fold over safety clasp with push button release. The 32mm (approximately 1 1/4″) case width does not include the crown or crown protector, and like most Reactor watches has a large case about 12mm, or 1/2″ thick.

The numerals are coated with Reactor’s high quality Swiss Superluminova and Tritium tubes are placed at the 12, 3, 6 and 9 positions as well as the minute and hour hands for viewing in any lighting condition, day or night. The benefit of this system is that the Tritium will glow continuously without re-exposure to light, unlike the Superluminova which will fade over time. Because both applications are self-illuminating, you don’t have to worry about the battery being depleted like on watches that have a back-light or LED light illumination at the press of a button.

The image below displays how Never Dark works, initially shutting off the light you can see the entire dial illuminated by the Superluminova application and as that fades without further exposure to light, your eyes adjust as the Tritium becomes more apparent.

This watch is also available in men’s model 68091 or you can shop our entire line of Reactor Watches at
