It depends on how radioactive it is and if the radium paint is crumbling. The biggest dangers are them emitting radon (a radioactive noble gas that is part of the Radium decay chain) and paint that is crumbling of. One of the watch hands leaves quite a bit of the paint everywhere it was. Most clocks and watches I have don‘t leak any but loose watch hands do. Wearing Radium watches can be pretty safe to wear if the watch isn‘t too active. I have done it a few times before, but I wouldn‘t wear it everyday for many years.
