Lume question
How long is the lume on a Rolex supposed to stay illuminated? I hae a preowned 2015 Datejust II 116300. I love it, but I've always wondered about the lume. it looks amazing for a few minutes after i've just been outside in the sun. But sometimes I hear people talk about being able to tell the time when they wake up in the middle of the night in a pitch-black room. I've certainly never been able to do that. Is my lume unusually weak, or is that what I should expect?

Sounds about right.
But also depends on your level of expectation and experience. It's never going to glow as intensely or as long as a professional model like a divers watch. It pretty much comes down to the sheer volume of lume. The more the better |

It glows really bright for about 5 minutes. For me, it is still readable maybe 6 hours later if I wake up and check the time and my eyes are used to the dark.

The only Rolex I have so far worn 24/7 is my three year old Explorer Polar. In a dark room with your eyes dark adapted it glows bright enough to reflect off white sheets for up to 14 hours, probably longer.

Charge it up with a UV light and then set your alarm for the middle of the night. You'll likely be able to see it. That initial brightness goes away after a few seconds, and then your eyes have to adjust to the dark in order to see it.

If I charge my Sky-Dweller or Explorer II with a uv light before going to bed the damn watch keeps me out of my sleep because of the lume.
14 hours withh eyes adjusted to the dark is about right |
