anyone know about this watch?

I have been given this watch, which has been in a cupboard for at least 40 years. The crown is fairly stiff, but I can set the hands (no hacking seconds), and I was able to wind it and it ran for a day or so, so it works. A couple of the lug holes look a little marginal, so it's been worn plenty. I can't take the back off, though I'll take it to someone soon.

Anyone know about the model or anything else about it?

And based on this poor pictures, i can say that the dial looks redialed. Look at the markers, for example the one at 7. Poorly outlined.
