Hello, this watch belonged to my great grandfather. I just got a hold of it. It’s not working (I can set the time but can’t wind it), so I opened it up to see if there was some info on the movement, but I can’t find anything online about it.

On the dial it says “Longines Suiza”, which would be Switzerland in Spanish. It has blueish hands and a heavy patina. The glass (seems to be plastic IMO) is heavily scratched and cracked.

Inside, on the movement, it says “Longines 7024138”. It doesn’t…
