The Breitling Watch Source Forums

Maybe I didn't have as much of a problem as I thought after all. I wrote my comment based on my experience with my 25 year old chronomat. But, last week I got a new Galactic 41, and I noticed I was out in the sun 5 minutes and then went into a dark room and it glowed super bright and lasted quite a long time. Maybe it has something to do with the older watch.

I'm curious as to what watches are producing that kind of duration for you. None that I've ever owned have glowed like that, including my Breitlings.

You watched it in one sitting didn't you? ...and solely to determine if the lumes would make it all the way through.

the newer method of lume offers colour variation as well , my 116613LB has a blue-ish Lume not green-ish My 16610 has a green-ish lume i think Rolex are experimenting with this

Not sure if it's an experiment, but Rolex did deliberately shift to blue lume on a number of its updated models. Some of the new Omegas have different colored lume on a single watch. Then again, tritium tubes come in a wide array of colors, as well.

SL is produced in about 10 different colours / shades from memory - nothing to do with Rolex or any other manufacturer, it's the manufacturer of the lume (RC Tritec), presumably in conjunction with Seiko and Nemoto who they license it from. The different colours do affect the luminous properties - i.e. some colours are better than others from a pure photoluminescence standpoint.

Just trying to be of service!

I've seen reports (one from Sharkie, if I recall) that the blue lume on the new Rolexes doesn't glow as brightly as the green lume. I can't remember if he said it lasts longer or not. Can you refresh my memory, Tom?

All of my (modern) watches glow all night off of a short charge, I rely on them to tell the time when I open my bleary eyes to get up for work at stupid o'clock in the dark.



I'm sure I remember that green is the colour of light that the human eyes are most sensitive to, hence laser shows usually being green and cheap green laser pointers giving off a visible "beam" where an equally bright laser of a different colour won't? Is it the same with watch lume (green will appear brighter to the wearers eye even if it's not?)

No idea, but different colours of SL have sifferent photoluminescent properties - it's not perception, it's chemically different.

I had come across this chart (see link) a while back on a WUS post (2nd one down), gives strength of the different Lume colors/formulations (assuming same quantities are used ?)

Good reference for lume specifications.

Yeah, I've seen that before, I think in one of the magazines - didn't remember so many colours though.
