Glowing watches are not only about the enchanting appearance but also a practical function for watch enthusiasts. Super-LumiNova watches have been around for quite a while now. It allows the wearer to tell the time despite being in a dark environment. 

Watches that glow in the dark were once considered one of the most technologically advanced developments in horology. Throughout time, it still becomes a crucial part of a timepiece. Super-LumiNova is an example of a popular lume which is the most commonly used one. 

It becomes the go-to choice for many watch brands, especially considering it is a Swiss-made illumination product. Many renowned watch brands use Super-LumiNova to make their watches glow. 

A Brief History of Lume Watches

As mentioned before, watches that glow or lume watches have been around since decades ago in 1910. It became a highly needed instrument, especially for the soldiers who needed a legible watch in the dark during World War I. Throughout time, some upgrades were made to suit the modern world. 

The glow in lume watches is a result of the mixture of radium and zinc sulfide. In the past, little knew that the mixture was a dangerous compound and highly radioactive. The discovery was found late when many workers died from the exposure. 

Unfortunately, it didn’t teach those manufacturers to find a safe alternative material. Instead, they produced another radioactive material called tritium. In fact, tritium is less harmful compared to the original mix used as a lume. Therefore, we can still find some manufacturers use tritium for their watches.

The First Use of Super-LumiNova

The story of Super-LumiNova can be traced back to 1940s during the World War II. It is Kenzo Nemoto who owns a luminous painting business and opens services to the Japanese military. After the war ended, he started using luminous coatings for watches and clocks. 

That marked the establishment of Nemoto & Co that after several years managed to introduce LumiNova, a new pigment technology called phosphorescence. The company, then, registered the patent of its invention and had the authority to give out licenses to other manufacturers. 

From then, the Swiss brand RC Tritec AG acquired the right to produce the luminous product under the name of Super-LumiNova. Therefore, Super-LumiNova is a Swiss-made LumiNova that many watch manufacturers use today. 

So, how does it differ from the original version?

Super-LumiNova is way safer than the original LumiNova. It doesn’t contain any radioactive chemicals which makes it safer for workers and wearers. The pigments used in Super-LumiNova flaunt great resistance to many environmental changes. 

Further, the product also meets the standard set by the European Chemicals Agency that further enhances its safety. Super-LumiNova is sold in powder with various qualities and colors that we’ll discuss in the next section.

Color Coded Coolness

As mentioned above, the manufacturers can choose among different grades and colors of Super-LumiNova. Some might use bluish lume while others use green lume or other color choices. Let’s have a detailed discussion below!

Afterglow Colors

Most Super-LumiNova watches have eight main afterglow colors, namely:

  • BL – Blue Line – blue emission
  • GL – Green Line – green emission
  • VL – Violet Line – violet emission
  • WL – White Line – complete white emission
  • YL – Yellow Line – yellow emission
  • OL – Orange Line – orange emission
  • PL – Pink Line – pink emission
  • UL – Ultramarine Line – ultramarine blue emission

Before the release of Super-LumiNova, blue and green are the most common colors on most luminous watches due to the way human eyes interpret the color brightness. But today, manufacturers can have wider choices, especially to further enhance the design. 

This invention made a breakthrough in the watchmaking industry as it brings many other opportunities. Further, RC Tritec also offers custom pigments for those who want to have specific hues to replicate or match a certain timepiece.

Grade Levels

Not only that Super-LumiNova comes with different afterglow colors but also qualities with several grade levels. There are different formulas for each grade that results in different lume performance. 

As of today, there are three grades of Super-LumiNova as listed below:

  • Standard Grade
  • Grade A
  • Grade X1

Grade X1 is the most recent formula and is considered the best-performing one than the others. It improves up to 60% after two hours compared to the Standard Grade although the company doesn’t release further information if compared to Grade A. 

Technically speaking, Super-LumiNova watches would glow brighter if the manufacturer applied multiple levels of lume to the watches.
