·The only problem with this theory is that I have the same material in the inlays on my 1961 Seamaster 14761 and it neither reacts to UV light nor to a Geiger counter. Since radium has a 1,600 year half life, the Geiger counter would pick up more than just background radiation if the inlay material was radium based lume and it should also react to UV light exposure. Negative for both with my watch.
That watch is bewitching for someone like myself. I am a sucker for that model which my late father wore for decades when we traveled most parts of the world . Watch was never found when he passed away in hospital after all the confusion that went on. Not suspecting that someone took it but it was never found but looks like yours with the same dial. I think he had a greyish dial or patina had turned it grey.
Now regarding your comment that your watch, from the photo you provided, it looks like your hands have black paint in the slots made for lume and your markers look almost darkish brown to almost black.
The other issue with your very valid comment is that Geiger counters are not always a reliable tool in evaluating radioactivity on a dial according to this post in

Maybe yours is not radium and looks like ones that do have radium where the inserts may have been replaced by an imitation at some stage of what was there originally!! If you have owned the watch new then you would know its history
Interesting topic regardless. !!!
