T100: World’s Brightest Tritium Illumination

Available exclusively on Massdrop, this Isobrite Valor Watch Set from ArmourLite features a lightweight Valor watch in three different dial colors, plus three bands and a few other extras to prepare you for the field. The dial features bright markers containing tritium—an isotope of hydrogen that glows in the dark—while the carbon fiber-reinforced polycarbonate case is equipped with a push crown and an anti-reflective scratch-resistant sapphire crystal. This version is outfitted with T100 tritium illumination, which is four times brighter than the T25 variety used in most standard tritium watches. Manufactured by Switzerland’s mb-microtec, these tritium markers are currently the brightest and longest-lasting available in the world.

Note: At checkout, choose between blue, orange, and yellow color options. This drop is limited to 45 total units.

A unidirectional bezel helps keep track of elapsed time, while a display between 4 and 5 o’clock tracks the date. Also included in the set are three separate wristbands, a pin remover tool, a keychain compass, and a zippered travel case for storage.
