It can be frustrating when you are unable to read the time on your watch due to poor lighting, but you can solve this problem by purchasing the watches with luminous dials. Luminescent dials are relevant for reading the dial in the dark- particularly underwater. All divers watches must be equipped with a luminescent dial.
Variety of materials and chemicals have been used over the years to bring luminescence, or lume, to wrist watches. The early practice of applying lume to wrist watches, around the time of World War I, involved mixing the radioactive material radium with zinc sulfide. However the glow of radium alone was not bright enough and the amount required to make it useful would emit too much harmful radiation. In 1968, the use of Radium in wrist watches was banned requiring alternative methods of lume to be used. Tritium became the material of choice. The difference between radium and tritium is the level of radiation and half-life of the materials. The measure of radiation in radium is at the top of the scale with a 20 while tritium is at the other end with a ranking of 1, or about that of getting an x-ray. In recent years, tritium has made a comeback after in the form of tritium gas tubes. These small glass tubes contain a phosphor layer inside and are filled with tritium gas; these are known by gaseous tritium light source (GTLS). The tritium undergoes beta decay which releases electrons that trigger the phosphor layer causing it to glow.
