How many years does lume last?
Some say it was designed “to far outlive the life of the watch.” By that standard, we’re talking 15-20 years easy for a 3133/complication. Another figure I saw said 20% decrease in luminosity for every 2000 hours of exposure to light (so, completly dead in 2-3 years).
Does tritium glow forever?
Since Tritium is radioactive, it will glow whether or not it receives any light exposure; however its ability to glow is limited by the radioactive half-life of the material itself. This means that as Tritium ages, its ability to glow will diminish until the point that it ceases to glow at all.

Does lume degrade over time?
With a half-life of about 12 years, barely a fifth of the radioactive material is remaining after around 24 years. Many watchmakers, including the most well-known luxury watch company, Rolex, have used tritium over the past. Rolex abandoned the use of tritium after its use as a lume paint was outlawed in 1998.
How long should a watch lume last?
“Lumibrite is a virtually permanent, non-radioactive, fluorescent coating that can light up the face of a watch, or just its hands and numbers, for up to five hours after two minutes exposure to sunlight.”
How long does Breitling lume last?
My guess is that it is tritium and that ages at a predictable rate, the practical lifetime of regular tritium lume is 20 years or so and it fades as it gets closer to that age. No real solution other than to see if Breitling can relume with SL during servicing. Roffensian wrote: It’s probably tritium like at that age.
How long does radium lume last?
The radium would glow all night. This phenomenon would last for many years, sometimes up to 50 years, since the half life of radium is 1600 years. But eventually the base paint is broken down and destroyed by the effects of radiation from the radium, and had to be replaced by the watchmakers.
When did Rolex stop using tritium?
When did Rolex stop using tritium? In 1998 once the use of tritium paint was banned. They have been using Luminova instead.
Is tritium illegal in the US?
Tritium does not in itself emit light but excites phosphors, thereby generating light. Due to U.S. regulations regarding radioactive substances, all of the above items can be legally sold in the U.S., as the manufacturers of such products require special licensing in order to integrate tritium into their products.
Which tritium color is brightest?
The difference between the signs is how much tritium the manufacturer installs. The light produced by GTLSs varies in color and size. Green usually appears as the brightest color and red the least bright.
Which watch lume lasts the longest?
When fully charged, most watches tend to glow the brightest for 4 to 12 hours before the luminescent glow loses some of its brightness, although not all of it. With that said, the most reliable lume on a watch will be tritium since it doesn’t have to be charged and lasts for a long time.
Is LumiBrite radioactive?
As its name suggests, LumiBrite starts glowing brightly in the dark and fades slowly. It is also completely free of radioactivity, ensuring safety for people and the environment. It is the ideal successor to both radioactive luminous paint and conventional fluorescent paints.
Does lume glow in the dark?
Pigments based on photoluminescent material (like strontium aluminate) are what are most commonly used for watch lume today. This non-radioactive material is painted onto hands, numerals and dials, then glows in the dark (in usually a green or blue hue) by absorbing light then re-emitting light.

How long does Rolex lume glow?
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.
Does watch lume wear out?
Most watches made after the 1990s will have Super-LumiNova or a similar material, (strontium aluminate photoluminescent lume) that needs to be “charged” with a light. SrAl is chemically and radioactively inert, so it should basically last forever regardless of use.
How long does lume last submariner?
Read what Rolex wrote in the Submariner brochure: The Chromalight display on the dial is an innovation that pushes the boundaries of visibility in dark environments. The blue glow lasts up to eight hours with a uniform luminosity throughout, practically twice as long as that of standard luminescent materials.
What lume does Rolex use?
Luminova and Super-Luminova
By 2000, Rolex had switched to Nemoto & Co’s Super-Luminova, a strontium aluminate lume. This lume compound stores photons when exposed to sunlight or artificial light, allowing it to glow in darkness for hours after initial light exposure.
Is luminox radioactive?
Conclusion. Luminox were pioneers of GTLS technology. By partnering with MB-Microtec they have been able to safely use radioactive Tritium in watches.
Does UV light damage lume?
The answer to that is that lume decorates a tiny tiny bit every time it is charged, but UV light does not particularly degrade it, and it is not something you have to worry about.
How does tritium glow?
The tritium emits electrons through beta-decay, which excite the phosphor and cause it to emit visible light. This tritium glow light here will illuminate for ten years and can be seen from up to 30 feet away. Its marketed use is as a ‘self-illuminating safety device’ for identifying a location in hours of darkness.
Are tritium watches safe to wear?
But because tritium is mildly radioactive, and feared by some to be a health hazard, tritium paint is no longer used on dials. (The consensus among scientists is that, despite consumers’ apprehensions, tritium paint on watch dials presents no danger.)
What makes a watch face glow in the dark?
Instead, it incorporates a material known as strontium aluminate, which is an extremely efficient phosphor that once charged, will glow very brightly initially, and with diminishing intensity for several hours thereafter.
Will Super-LumiNova patina?
And here we’re getting to the disclosure of our quest. Luminova and (Swiss) Super-LumiNova are not prone to discoloration or ageing over time. They don’t fade, nor will interact with moisture.

Will Rolex replace a tritium dial?
As Rolex does not use radium or tritium for its dials anymore, a service dial will have Luminova or super Luminova.
Do Datejust have lume?
The Rolex Datejust II 116334 features lumed Arabic numerals in blue lume and hands with green lume, for a unique effect.
