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.
mb-microtec ag is the only worldwide manufacturer of this unique watch illumination technology. The fabrication of the self-illuminating trigalight® is the result of decades of research and development. trigalight® illuminates watches without requiring an external power supply or sunlight.
