I imagine it depends on the dial, since some have lume and some don't. There might even be more styles.
Curiously, I have not come across dials with lume pips. Perhaps I need to look longer, and perhaps they’ve just fallen off and been removed.
Also dials don’t seem to show radium burn, which makes me wonder what the lume material is on these plongeur hands.
The dial lume is often on the numerals. Some numerals are lumed, some are painted. You need to look closely at good photos.
Oh now this ones interesting. That green looks like radium. Did you ever take a giger counter to this? After ~80(?) years of radiation exposure, wouldn’t the dial be more toasty looking?
And yes again to non-lume dial, non-lume hands....
I did - it was off the charts - I sold the watch!
Don't forget the radon gas they emit when decaying. Radium watches kept in non ventilated areas is deadly. I have a radon detector and it shocked me. Was like 10x safe levels with only one watch.
How would you define a non ventilated area? Is there any room in a residential house that would be considered non ventilated?
