Here’s a watch my grandfather left me a few years ago. I’ve looked all over the internet and I’ve found exactly zero information about it, but two things I’m sure of - it dates to at least the 1950’s, and the dial is radium paint. That’s right! I’ve got myself a little radioactive watch.
Is it dangerous? As long as I don’t open it up and lick the numbers or snort the dust contained inside the glass, it’s perfectly alright. But that also means it’ll be next to impossible to get it working again.
