Help pls on assessing this Pie Pan Constellation

Hi everyone! New here. Am looking for a pie pan Constellation that I can wear on a regular basis. I am OK with a bit of polishing, but would like all accurate parts as far as possible. No redials.

I'm reading OF and Desmond's amazing amazing site. But I don't know if my judgement is accurate enough so would like to check with you all.

Seeking your views please on this Pie Pan Constellation please.

Seller says it's:
- Ref. 2852 8SC
- Caliber 505
- original crown

1. How badly polished does the case look?
2. How worn does the movement look to you?
3. How do I tell if the crown really is accurate?
4. Do I need to be concerned about corrosion on the hands?
5. What have I missed?

Asking USD 1,400. It seems high to me, but I'm new to this and would appreciate any comments on what pricing I should be looking at please.

Looking forward to learning from all of you. Please feel free to let me know what you think. Hope I didn't offend either. Thank you in advance.

Thanks TexOmega. Will update if I can get better pics. (I guess if I can't that means I should move on.)

The case doesn't look overpolished, if it was even polished. Edges still appear sharp. I don't mind some rusting on the hands and tarnishing on the dial, but it's a personal thing. The crystal seems to have the original omega etching in the center too. Quite a nice find!
