ArmourLite Isobrite Tritium Desert Tan Watch Kit

Available exclusively on Drop, this Swiss-made Isobrite desert tan watch kit from ArmourLite features a lightweight T100 tritium-illuminated watch in two different colors. The dial features bright markers containing tritium—an isotope of hydrogen that glows in the dark—while the carbon fiber–reinforced case is equipped with an anti-reflective scratch-resistant sapphire crystal. The T100 tritium is up to four times brighter than the T25 variety used in most standard tritium watches. Manufactured in Switzerland by Trigalight, these tritium markers are currently the brightest and longest-lasting in the world.

Water resistant to 200 meters, these watches are scuba approved and ready for any type of weather. For accuracy, each watch is powered by a Swiss Ronda 715Li quartz movement with a 10-year lithium battery for longevity. A unidirectional bezel with two tritium markers helps keep track of elapsed time, while a display between 4 and 5 o’clock tracks the date. Also included in the kit is a desert-tan nylon band, a green nylon band, a desert-tan Velcro band, a spring bar pin tool, a 35-millimeter compass with a nickel key ring, and an elegant display box.

Based in Miami, Florida, ArmourLite Watch Company designs and manufactures Swiss-made tritium-illuminated watches for military and law enforcement personnel, first responders, and rugged outdoorsmen under the brands ArmourLite and Isobrite. Known for their accuracy and reliability, most products in their collection feature a shatterproof crystal, and all Isobrite models come with Swiss T100 tritium illumination—the world’s brightest.
