Help identify factory, cleaning inside glass

[Badz]

Hi all,
I have a Rolex sub Rep I brought in 2018,
Two questions if you people could be so kind to help me with,
1st if I put up some photos would it be possible to work out the factory it would of come from?
2nd there seems to be some sort of mist under the glass, doesn’t look like condensation but something close, and is noticeable when you hit the sun on it at the right angle, can this be cleaned?

Yesssir! Absolutely! Post some pics if you feel like it.

It might be nice to share which 3 numbers or letters are engraved on the inside of the clasp. That's one more simple way to identify which of some of the better quality factories it might have come from.

Thanks for your reply, have loaded some photos up, not the best, can try and get some better ones if needed,

Also really hard to capture the most I was mentioning

Thanks for the pics man. Very low tier watch. Probably cost around 50 dollars when it was new.
You might be amazed at how nice the popular factories' watches are quality-wise if you grab one.

I would love to buy a really nice rep, and I know you don’t see the internals but would love one with the decorative movement,
