Please help in indentifying this watch!

So I have this watch which had belong to my grandfather. I don't know the specifics as my grandmother does not know what make the watch is and she gave it to me. The watch does not work and it not in best condition based on how it looks. I want to restore it and make it functional, but I want to know if it is worth restoring this watch or its beyond repair.

Thanks in advance!

"I don't know the specifics as my grandmother does not know what make the watch is and she gave it to me."

Obviously, you got this part cover since you posted in the Omega forum. 😉

"I want to know if it is worth restoring this watch or its beyond repair."

You said it yourself "I have this watch which had belong to my grandfather" how much sentimental value does it have for you? If it was my grandfather's I would do whatever it takes to get it running. However, that is me.

"I don't know the specifics"

More specifics will be in the caseback, if you open it up.

Good luck.
