Lume time

How long should the lumination supposed to last on the dial. Not life of the lume but after it's been "charged"? 4 hours? 2 hours? Anyone have an idea?

Is Chromalight just a fancy word for the Luminova blue green? After being outside in proper sunlight mine will typically be readable all night...

Basically yes, I believe it amounts not much more than a different hue of SL that Rolex gave a special name.

In all honesty, in my experience it lasts about as long as the typical movie. And I've got to put it closer to my eyes to read it at around the 2 hour mark. That's good enough for me considering I can always give it a quick recharge with my cell phone. YMMV, but if I really needed all night lume I'd find something with trit tubes.

Mine lasts all night... but in a weird way. It never really blazes bright but emits a low lit light all night long. At least that has been my experience. I wonder if different people's eyes work differently?

The newer lume materials last longer than the older material. And if you have a Rolex older than 1998, the Tritium would be very weak by now.

But between Chromalight and SL I don't think there's much difference in how long they last or their fading rate on a charge. Perhaps people can see the color blue a little longer but other than that I don't see much difference in actual performance.

Chemically, aside from the pigments isn't it essentially the same active ingredients in both?

I agree. I meant SL vs older first gen LumiNova. Also vs other early lume materials - SL is touted at ten times higher brightness than previous zinc sulfide–based materials.
