Looks like if there was, it is long gone- someone beat you to the punch. A relume with an appropriate color (like butterscotch) by a skilled ...relumer (?) on the pips and hands would really bring that dial to life.
Now there may be residual radium dust in the case, so I would proceed with caution- wear a mask when opening (which is fashionable these day’s anyway) tap out the movement into a piece of paper and wipe out the case and crystal with a damp napkin (disposing of all in a ziplock) before going at it.
I’d say, most definitely it was a radium-dialed watch.
Like JW said, be careful. It’s very difficult for a watchmaker to remove every bit of radium from those nooks and crannies. Even with mask and gloves on (dispose into ziplock afterwards), do NOT be near (6 feet? ) the watch right after opening, since radon gas (radioactive decay byproduct of radium) may have built up under the crystal even with residual amounts of radium present. Probably not much, but better safe than sorry...
Beautiful little watch, btw!
I don’t think it’s necessary- either way it’s gonna do what it does and it looks like the worst is already gone. You just want to avoid any contact with mucus membrane- so don’t lick out the case to clean it up.
I thought it had a half life of 800 years. That means its only 63 years into its half life so while it may not glow its still incredibly dangerous. I see a lot of conflicting opinions and mis information and im trying to get to the bottom of it. As tempting as that is i shall refrain from licking it for now
