SuperLuminova

[Rolex Lover]

Folks,

Depending on the superluminova brightness, for how long can a Submariner -for example- be luminous after being exposed to sun for couple of hours???

Thanks,
Ahmed

I think if you expose the SL to sun for 10 sec it'll stay visible for same amount of time as if you let it sit for 2 hr under the sun

I don't think it's related to how long it stays in the sun. The radioactive particles (I don't know if this is the scientifically correct way to describe them) become more "agitated" with sunlight than with artificial light, so sunlight will keep it "charged" longer. It continues to emit light energy for like 10 or 12 hours, it just becomes less visible after two or three hours (depending on how old the SL material is).

I can still see mine in the morning, after 7 hours of sleep...but it's dim. It has to be really, really dark in the bedroom for me to tell the time.

It doesn't matter whether its 10 minutes or 10 hours, the lume brightness dulls to a light glow in about 30 minutes, Rolex is not known for having great lume!

Hi Ahmed,
There is no differnce between haviing it maybe 30 seconds under a light or a few hours in the sun.
Where you have for sure massive differences in between the same models even the same year are the Vintage models....

It is my understanding that Tritium degrades over time. Superluminova does not. A 10 year old watch should be as bright as a new one if they both have SL and it is applied the same to each watch.

My 2 SeaDwellers hold true to this hypothesis. One is 9 years old, the other is less than a year. The SL on them is the same.

Hi,
SL changed its consistence mid 90s, so there is a difference.
That is what you can also see on the 16600 and 16660....

I don't know if I am ansering your question but my Sub LV (when fully charged) lasts about 3-4 good hours. No Rolex has great lume but the LV lume is better than I expected.
