Tritium Watches: Trigalight Illumination Technology

Watches in this category have hands and hour markers equipped with trigalight® tubes that are self-illuminating and do not require charging with light or an external power supply (i.e. a battery). trigalight tubes glow up to 25 years and are maintenance-free. mb-microtec ag is the only worldwide manufacturer of this unique watch illumination technology.

trigalight® are tiny glass tubes which are coated on the inner side with a thin layer of phosphor powder, then filled with a minute amount of tritium gas and sealed airtight. Once the phosphor powder is exposed to the electrons from the tritium gas, it excites the phosphor to emit light in different colors. The light is visible in both low light and complete darkness.
