How can you see the hands of your watch even in the dark? Quite simply, thanks to the Super-LumiNova on the hands of your watch. This blue-green gel allows the hands to glow in the dark and thus tell you the time. In this article, we will see in more detail the characteristics of Super Luminova on a watch.

The Super LumiNova, a substance rather difficult to find

Since the possibility of reading the time on any occasion, it was necessary to find techniques to make this reading at any time of the day and night. That's why Pierre and Marie Curie looked into the problem and discovered radioactive materials. This was the beginning of the association between chemistry and watchmaking. But the problem arises concerning the radioactivity of the products. To overcome this problem, a few years later, chemists used titanium. This product had a big advantage: to be less harmful. It also had a disadvantage and not the least, its life span is only 12 years. Thus, the partnership between a Japanese company Nemoto and a Swiss company RC Tritec allows the world of watchmaking to find THE solution! The owner of RC Tritec brought back from China a luminous ceramic based on strontium aluminate. In 1994, the LumiNova patent was registered. This process is not only used in the world of watchmaking, but is also used for signage, for example.

The effect of Super-LumiNova in a watch

Super-LumiNova accumulates energy when exposed to ultraviolet light. When the light source is turned off, the accumulated energy is released as light. This phosphorescent pigment Super-LumiNova does not degrade over time and therefore allows with its blue-green color to read the time on your Charlie Paris watches at any time. This system is indeed present on the GR and Concordia men's watches, which are automatic watches for men, also available in quartz version.
