So lets take any item, polish anything you want, then provide good pictures and say its "great" condition.
Yes, it's fairly common amongst people who sell things to say something positive about the item for sale.
Why is it so bad to have people look and give opinion? I believe in inspecting item after receiving.
You didn't inspect it, you sent it to someone else to inspect, and he wasn't sure so he needed a second opinion - and a microscope.
So what you're saying is that I'm supposed to decide based on pictures provided only?
Yes, eBay for example has quite a successful business model, based on this very principal.
We can all take any part, polish where needed and then say its very good condition. Correct?
Opinions are subjective, which is why you shouldn't pay too much attention to them, especially in a sales ad - make up your own mind as to whether the item is in 'great' condition or not.
If the bezel is in "great" condition, why he did not say it was polished?
Did you ask him if it had been polished ?
You are the purchaser, you should know what you want, what is important to you, what is not. Expecting the seller to know what you want is unrealistic.
You made a mistake, you assumed that the bezel would be perfect because that is what you wanted.
Sell the bezel, you'll get your money back from it, then you can buy a new in blister pack bezel. This one here isn't in it's blister pack, but it's in new condition - $4000 US:
