Need help authenticating!

[radbone]

Hi All! New here and was hoping to get some feedback from TRF on a vintage GMT Master I found on Craigslist. It’s supposedly a 16753 from around 1987. This question is two parts and hopefully doesn’t break any rules:

1) does this look legit?
2) what would you pay for this piece if it is real? Seller currently has it listed for $7,125 (USD)

I went to take a look at it and everything *seems* legit but I was unable to take a look at the movement or see the inside of the case back. The bracelet doesn’t have any steel showing under the gold.













Any and all help appreciated!
