ArmourLite Caliber T25 Tritium Automatic Watch Set

Available exclusively on Massdrop, this set features the ArmourLite Caliber Series Automatic Tritium Survivalist Watch and a host of extras. The watch is powered by the natural motion of the wearer, so it needs no battery replacement. For visibility no matter the lighting conditions, the dial and hands feature green and orange markers containing tritium: a self-powered isotope of hydrogen that glows bright in the dark and requires no external power source. Designed for divers, outdoorsmen, and sportsmen, the watch has a carbon fiber-reinforced polycarbonate case that’s equipped with a double-gasket push-in crown and an anti-reflective scratch-resistant sapphire crystal. This set also includes a nylon strap, a Velcro strap, a display box, and a pin remover for band exchange.

Water resistant to 200 meters, this automatic watch is scuba-approved and ready for any type of weather. For accuracy, the watch is equipped with a Seiko NH38 automatic movement with 24 jewels. The open-heart dial gives a small glimpse into the internal mechanism, a symphony of moving parts at the 9 o’clock position. The unidirectional ratcheting dive bezel with calibrated clicks helps keep track of elapsed time.

The first manufacturer to combine shatterproof glass construction with tritium illumination, ArmourLite caters to military and law enforcement personnel, first responders, and outdoorsmen. Based in North Miami Beach, Florida, ArmourLite aims to create the ultimate combination of accuracy and reliability in each of its designs
