I've never really gotten a lot of info on this watch- the first vintage one, picked up a year ago and got me interested in the history. I picked it out of a bin for $5 and wound it up and it ran for a bit. Needs work, but I'd like to see if I can get any more information on it. I know Alpha is a sort of generic Swiss company, but I don't know much more than that. This looks earlier than 70's. The corrosion on the hands and numbers is pretty severe... radium? Thanks.
