Does Rolex use Super-LumiNova?

Tritium is not as radioactive, however, it does lose its glow over time, as well as change color to yellowish. Today, Rolex uses either superluminova or Chromalight for luminescence, and as mentioned, we will focus on Chromalight in this article, but also touch upon Superluminova as well.

How long does Super-LumiNova last?

Super-LumiNova lasts the entire lifetime of your watch. It doesn’t fade, decay, or age. Luckily for watch enthusiasts, the Japanese enterprise, Nemoto & Co. introduced a LumiNova pigment in the early 1990s.

Does Super-LumiNova fade?

Luminova and (Swiss) Super-LumiNova are not prone to discoloration or ageing over time. They don’t fade, nor will interact with moisture.

When did Rolex switch to Chromalight?

2008
CHROMALIGHT. Finally, in 2008, Rolex unveiled their exclusive photoluminescent material called Chromalight. This is the first luminous material to be developed by Rolex. Chromalight, according to Rolex, glows more quickly and can last up to eight hours, which is more than double the time of other luminous materials.

Why does my Rolex not glow?

Prior to the widespread implementation of photo-luminescent material, Rolex used a radioactive compound called Tritium to make their hands and dials glow in the dark. This means that as Tritium ages, its ability to glow will diminish until the point that it ceases to glow at all.

Is Super-LumiNova radioactive?

Super-Luminova does not contain radioactive material. If the previous luminescent uses radioactive material, Super-LumiNova does not contain radioactive at all. Although radium watches are not dangerous for everyday use, it seems to be more assured if we do not use radioactive particles on our wrist.

Is Super-LumiNova toxic?

Modern solutions are much safer to use. The two popular types of watch lume nowadays are Tritium (radioactive but safe to use) and Swiss Super-LumiNova, which is completely non-radioactive, non-toxic and based on a formula consisting of strontium aluminate.

Why did Rolex stop using tritium?

Rolex started using tritium for its watches from 1963. Whilst tritium is also radioactive, it has a much lower level of radiation. Tritium has good luminous characteristics and glows rather strong, but an issue is that it has a 12-year half-life (due to the Lowe level of radiation), which means it will stop glowing.

Should my Rolex glow in the dark?

What is the best SuperLuminova?

There are many different suppliers of luminous and superluminous paints, but the two best known are SuperLuminova from RC Tritec of Switzerland and Lumi Brite, which is the superluminous paint used by Seiko in Japan.

Is SuperLuminova radioactive?

Tritium was then replaced by superluminova, a material that has the same properties as tritium, but is not radioactive and thus more environmentally friendly.

How can you tell the difference between Rolex Chromalight and superluminova?

Rolex Chromalight glows blue in the dark, and this is, therefore, a way in which you can tell SuperLuminova apart from Chromalight. The Chromalight material was announced in 2008 when Rolex released the Deepsea Sea-Dweller, a watch that demands a strong and reliable lume.

What’s the difference between Luminova and superluminova?

Luminova and SuperLuminova is based on strontium aluminate, mixed with a resin binder. They are both brand names belonging to Japanese company Nemoto & Co., and they are virtually identical: SuperLuminova is used by Nemoto & Co’s European partner Tritec. Chromalight is Rolex‘s own version of SuperLuminova, patented in 2008; it glows blue.

What are the colors of Super LumiNova watches?

There are a variety of lume pigments available. As you can see in the lumeshot comparison above, microbrand Marc & Sons went with a bluish lume for their pilot watch and a green lume for their diver. Most watches with Super-LumiNova will use one or more of the following color codes:

What do you do when the superluminova runs out?

Chromalight is Rolex ‘s own version of SuperLuminova, patented in 2008; it glows blue. The ultra-violet radiation in daylight and in some artificial light sources adds energy to the electrons in strontium aluminate pigment, which then slowly releases it in the form of photons (light) over the course of the next few hours.
