I got this watch after my grandfather, I think he buy this in the 1940-1950’s, is it anyone who now something about this watch. I like to repair it and use it, I can’t find anything about this watch on the internet.
You can't find anything because the information you need is inside the watch. If you'll provide photos of the movement and inside the case back, you'll get more help.
Ok thanks, I just have to wait to see what the watchmaker can find out, but what is the age do you now.
