Opinions on this 5513 are greatly appreciated!

Sorry to keep pestering you experts! If all checks out with this, I promise it'll be the last

I apologize for the photo quality- these are the best the seller can provide at the moment. No movement pictures, but I plan on getting the case back opened before I purchase.

It is a 2,7 million series 5513. I understand that the bracelet and crystal have been replaced, but otherwise, is everything period correct? Is it a decent buy or should I pass?

Lastly, what would be a reasonable offer for it, in its current condition?

Thanks again, you're all saints!
