Sorry if this was discussed before, but searches didn't help...

Both EXP II and Sub brochures claim
"The blue glow lasts up to eight hours with a uniform luminosity throughout"

Based on this article http://www.minus4plus6.com/216570.htm it appears that you have to be outdoors all day.

Anyone else test this out?

Would half a day = 4 hours?

Thanks!

Don't believe everything you read literally..

The time it takes to "charge" takes only a short time.. Charge time does not relate to discharge time..

If you are out in the dark, and stay in the dark, you can see the lume for quite some time... go inside though (or look at a bright source such as a movie screen, and your eyes readjust and it will take some time to be able to see the lume again...

Rolex are not known for their lumen. That is nothing new. Some new models are better but not great. This is an unusual when I think of any Omega SeaMaster with the sword hands from 10-15 years ago - watches which possessed amazing lumen which would last 'glowingly' through the longest night. I miss those Omega's for that reason and truly wonder why Rolex never matched (has never matched) that feature....

I have a new EXP II and wear it to bed. Throughout the night and into morning I have no problem telling the time with the lume still glowing. Is it as strong as it was in the morning vs. night? No but still strong enough to tell the time pretty easily.

And on a typical work day I'm only outside shortly, if at all.

Lots of info on Lume (and specifically on charging in this section) HERE

My tag aquagraph was alot brighter and lasted longer when I had a rolex DS.

Once your night vision kicks in, the lumes on my Rolexes are liveable (even after 4-6 hours).

I can see the lume on my relatively new dj 36mm all night long. Just a short charge is all it needs. When the sun starts to come up just barely, I can no longer see the lume unless I look at it under the blanket.

Thanks for the link!

I guess I'll need to check my vision

Will run some experiments to ease my mind.

Wouldn't know. Don't use mine too much in the dark.

The blue lume stays legible much longer than green. My UN has huge indices with standard green superluminova. Although it glows super bright for a few minutes, my sub with blue lume is far more legible a few hours later, and a few hours after that.
