TAWATEC Tactical Watch Technology -Designed and produced by SMW Co. AG, Switzerland - Swiss Movement.
TAWATEC Tactical Watches are equipped with trigalight from mb-microtec. Trigalight is a light source that is a microscopic glass tube coated with a luminous substance, and filled with tritium gas (an isotope of hydrogen). The coating is bombarded with electrons emitted by the tritium gas (H3), which cause the layer to light up. (Conversion of the electric charge to light). This process occurs without use of any batteries!
Whilst in a television tube, the electrons are generated electronically through the use of a cathode, with a trigalight, the necessary electrons are created through the radioactive disintegration of Tritium (an isotope of hydrogen)
The disintegration electrons of the tritium have a range of just 1-3 mm in air and can’t even penetrate the human skin. The energy of (at most) 18 keV is not sufficient for this. Thus the disintegration electrons (beta radiation) do not have the power to penetrate or leave the sealed glass vessel of a trigalight.
