Ca. 1919 Omega Pocket Watch from my great grandpa. Should i restore?

Hello good people of the OmegaForums.
What a cool community, i have read many interesting articles and posts already, and now i feel ready to post on my own

Many years ago i inherited my great grandpa's pocket watch. I' ve had it on a shelf, but now I'm considering either having it restored or restoring it my self. It ticks beautifully when wound, but has some serious cosmetic flaws. The silver back plate has come loose from the casing, and the enamel dial is badly chipped.
So i need help!
I need to identify more specifically what kind of watch it is, and if it is even possible to do anything to restore it. And will it be worth it? I'm not planning on selling it, but i would like to know its approximate value before trying to restore it my self f.ex.

I have no particular knowledge of watches, so i could really use a bit of advice from you guys.

I can date the serial from the casing to ca 1919 or 1920 (mid 5mil serial running from 1915 to 1923) but that is kind of it. I have no stories of its origin, it was just handed down to me, through family.

And it would be an awesome bonus if someone knows what the hand-scratched numbers on the inside of the casing means? Maybe assembler's ID? repairs? Something entirely different?

I hope you can spare a minute to help.
Thanks!

Okay, so apparently the movement is from 1912? And i guess the case is later then.
I got the year from running the movement serial through some random omega serial decoder... But it checks out with the lists i can find around the web.

Thats my fault, must have missed the photo of the dial/crystal side. I will upload that asap.
I get what you're saying. I guess i expected that answer. It looks to be a mouthful ☺️

The main question. Are you going to carry and use it?

If not. Put it in a little PW container and put it display

Case repair and dial repair could be costly depending on the total damage and some are not willing to pay the price just to have it sitting

It is a silver case, so that would have to be sent to someone who repairs cases. Dial would need someone proficient in enamel repair

Also movement cleaning

All in all. You could be into 3x it's actual value in repair work

There is the alternative of factory restoration...

It's terribly expensive and there will be a lot of work done, but it is a choice. Likely not one I would make. But show the dial, so we can help more.
