Like Scotch tape or Jet Ski, Super-Luminova is one of those brand names that have practically become generic terms. One of the most popular brands of lume used in watches today, Super-Luminova is the trade name for a phosphorescent pigment, essentially a glow-in-the-dark chemical compound based on strontium aluminate. Luminova was invented by Nemoto & Co, a Japanese company specialising in luminous paint for timepieces, which then formed a joint venture with a Swiss partner to create Super-Luminova that’s Swiss-made.

Unlike radium and tritium, which glow in the dark because of radiation, Super-Luminova is entirely safe, storing energy from exposure to a light source, which then causes it to glow.
