I was wondering if there was an idea way to store a watch to keep the lume as bright as possible. What I mean is, say 5 years down the road, I assume the lume won't be as good as it was new.

If I stored the watch out by a window when I wasn't wearing it, would the lume on that watch have degraded more than a watch I kept in a dark box when I wasn't wearing it?

Thanks for any thoughts!

With modern lume materials - Super-Luminova, Lumibrite, etc. - this is not really a big issue. Keeping a watch in the dark will, however, extend the life of the lume.

If you are interested in more info, there is an excellent article about lume here: LUMINOSITY IN WATCHES

Thanks for the reply! I had actually read that very excellent link already, but didn't find that exactly what I wanted, except that the stuff used on cheap watches and toys was unstable and decomposed rather quickly.

I won't worry too much about using the lume too much then. I was thinking about building a watch box with UV lighting and I didn't want to kill the lume on them too quickly.

thanks again!

You're welcome!

In the link it talks about "Light Fastness" for lume materials, but then clouds the results by saying that modern lumes will last ">1,000 Hours" after exposure to a 300 Watt High Pressure Mercury Lamp before lume effectiveness is degraded by 20%. OK. How much more than 1,000 hours? My guess is quite a bit more, but I don't know that.

In any event, your proposed light box with UV light would be significantly less energy than that, so I'm sure you will be fine.
