Where does the luminosity of my watch's dial and hands come from?

traser uses two different technologies. The in-house manufactured self-powered illumination technology trigalight®, world’s smallest tritium light sources. It consists of hermetically sealed systems, which function entirely without the need for external light or energy sources. This technology offers 24/7 light reliability, for more than ten years as of production date. The other technology is named Super-LumiNova, it is a material for the dials and hands. The Super-LumiNova material takes its luminosity from daylight or any artificial source of light. The watch should, therefore, be exposed to bright light to ensure the luminosity of the dial and hands in the dark. Please note that the intensity and duration of the luminosity may vary depending on the watch model, the colour of the Super-LumiNova material and the time of exposure to the source of light.
