Super-LumiNova and Chromalight are resilient substances. They don’t burn out after a couple of years like Promethium. But nothing lasts forever. Eventually, the lume on the watch will begin to degrade after some time.

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).
How long does radium lume last?
1,600 years
Watches were using radium as lume until the 1960s. Radium is a material that can potentially glow for over 1,600 years which is around the half-life of the material wherein which the luminescence begins to dim.
Does Chromalight wear out?
Furthermore, according to Rolex, Chromalight can last up to eight hours, which is more than double the duration of other luminescent materials. Following the Deepsea, Rolex began furnishing other sports watches such as the Submariner, Daytona, and GMT-Master II with Chromalight rather than Super-LumiNova.
Does LumiNova fade?
However, they are radioactive and have a half-life of slightly over 12 years. This means the intensity of the tritium-powered light source will gradually fade, generally becoming too dim to be useful after 20 to 30 years.
How do I recharge my lume?
To charge the lume of your watch, simply expose it to a light source (preferable those with UV rays) in order to ‘charge’ the lume of your watch.
What does Seiko use for lume?

Does radium Glow forever?
Radium dials usually lose their ability to glow in the dark in a period ranging anywhere from a few years to several decades, but all will cease to glow at some point. A radium dial clock from the 1930s. A key point to bear in mind is this: the dial is still highly radioactive.
When did Rolex start using Blue lume?

Luminova and Super-Luminova
In 1998, Rolex began using Luminova for the lume on its watch dials, a non-radioactive compound manufactured byNemoto & Co., Ltd. By 2000, Rolex had switched to Nemoto & Co’s Super-Luminova, a strontium aluminate lume.
