You don’t know what time it is? Do you find it hard to tell what time it is when you’re sleeping? This is the exact problem Swiss watchmakers set out to solve in the 19th century. By the end of that century, Swiss watchmakers began treating the dials of their timepieces with natural luminescent paint.
Today we have watches with luminous hands. So which are the best luminous watches for your need? With hundreds of watches online, choosing the best luminous watch can be confusing and time-consuming.
We’ve rounded up high-quality lume watches on a budget to help you with the search. Some of these timepieces feature Swiss movements, which give them the edge over other options.

What are luminous watches?
Luminous watches come with a feature that makes them easy to tell the time in the dark. These watches use different types of illumination technology. You can get a luminous watch that’s just a regular watch, a sports watch, or an outdoor watch.
Types of Luminescence
So where does this luminosity on watch faces come from? To achieve the luminosity found on most watch faces, watchmakers use diverse techniques.
We review a few of these techniques together with their advantages.
Tritium is a radioactive form of hydrogen. Tritium Gas Tubes found on the hour markers and hands on the watch dial contain this low-energy beta emitter.
Radioactive Tritium Gas produces a consistent luminosity that does not fade with time. So, with this illumination technology, you need not expose the watch in light for it to glow.
With a half-life of about 12.32 years, tritium will gradually fade becoming too dim to be useful after 10 years.
While this technique uses radioactive substances, it has some drawbacks.
After 20 to 30 years of using a tritium watch, it completely loses its luminosity since all the tritium will have decayed.
One other downside of tritium is that it has a relatively low brightness. Under certain conditions, this can be difficult to read.
Notwithstanding, watches with tritium tubes are completely safe to wear.
Tracers are phosphor-coated tubes filled with tritium gas. These tubes come in different colors: orange, blue, green or red.
The electrons emitted by the tritium are absorbed by the phosphor, which intends gives off light. Hence, these tubes emit no radiation. Luminox watches and Ball watches make use of this technique extensively.
Luminous watch paints
To move away from radioactive excitants, watchmakers use luminous paint for their watches.
With this technique, a fluorescent substance once exposed to light absorbs photons (electromagnetic radiations) and then re-radiates the photons. This we see as a glow on the watch face.
Over the years, various watchmakers have come up with their own version of the luminous substance. The two prominent types in the market include.
This is Seiko’s in-house luminous paint. It is the lume used on some Seiko and Citizen watches. Read more on LumiBrite.
Luminova & SuperLuminova – The History
LumiNova is a patented photoluminescent pigment created in 1941 by a Japanese man named Kenzo Nemoto. He discovered that mixing a combination of materials resulted in a highly luminescent material that could be used to coat materials. His invention gave birth to the Nemato & Co company.
Later down the years (1993), a Swiss company, RC Tritec AG, partnered with Nemato & Co. This partnership gave them the right to produce and distributed LumiNova paint in Switzerland under the name Super-LumiNova.
So the term Super-Luminova indicates the lume is 100% Swiss made. You’d easily find this luminous material in most Swiss dive watches. Many Swiss watchmakers use this lume for their watches.
