Tritium is adopted by American army, because high visibility is necessary element on the mission at dark place.
Tritium (known as hydrogen-3) is a radioactive isotope of hydrogen. Naturally occurring tritium is extremely rare on Earth.

This watch equips the tritium made in MB-MICROTEC in Switzerland which has advanced technology for tritium.
This self-powered lighting is much brighter than ever before (normal luminous lighting). Of course, this watch meets T25(Japanese safety standard).

It is great useful for outdoor activity or sport at night.
