Seamaster lume inquiries

Hi all, I've recently purchased a couple vintage Seamasters and was curious if anyone could give me some information on whether these watches have any radium lume. The black dial's hands appear to have something granular that has been chipped away and the linen dial's hands appear to have a light colored lume, but I haven't gotten a better picture of it yet (both photos are from sellers listings). The linen dial's lume color doesn't appear to be radium, but thought it would be better to check than to assume. Sorry if this is a topic that gets brought up a lot, I tried to look through the various threads on radioactive lumes, but all the information was case by case rather than any definitive answers. Any info would be appreciated, thanks!

If the lume on hands and dials are original, they should be radium.

That first one looks to be a pre-De Ville, I wasn't aware Omega was still using radium in this period, or in baton style hands. Do you have some examples of baton hand pre-De Villes known to have radium?

I’d love to know if anyone could confirm this. I opened the case to investigate the damage to the dial (I bought it knowing the feet were broken) and removed the hands to do so. I believe the dial was cleaned of any lume, but I’m having some serious anxiety about the whole thing. Keep thinking I could have possibly touched something and managed to ingest something somehow.

I see the radium in the second picture now, on the outside of the non cardinal indices, but I haven’t and won’t be opening the watch, so I’m not concerned about that one.

To the best of my knowledge, none of these had radium lume to begin with. As you say, the first one has had its dial cleaned at some point.

Thanks for the reply, this is reassuring. My main concern is the hands on that first one, since I opened the case. They were not the orange burned looking color that radium usually is, so I was pretty confident, but thoughts and ideas tend to run wild once planted.

The pre-DVs I’ve had were tritium. Black dial: Guessing tritium on the baton hands and looks like the lume has been removed from the hour markers during cleaning. And I have one currently that has the exact same dial setup as your gold linen one (but the hands on yours appear to be replacements?). On mine it’s clearly tritium.

I’m curious as to whether others agree, but a cheap UV flash might be of use. After exposure to UV light: On any radium watch I own, the lume will light up but instantly fade in naturally lit room. On a tritium watch the lume will similarly light right up, but will still be visible for several seconds in a naturally lit room.
