The pics look real, but you would need to check the watch in person to see if it's a a super clone.
I don't see any red flags. I would find out how it's running, though. That watch is anywhere from 14 to 20 years old. It may be due for a service. If you were to get it I would also make sure it's been water pressure checked before taking into water.
Edit - Also, the watch is missing some links, including one of the half links. I would make sure it will fit your wrist. If you need more links those run over $60 per link.
I am no expert, but overall it looks pretty good to me. I'd hope for a recent service, books, cards, etc. along with a reasonable price. 😉 Given that the seller has his own personal set of gloves, I'll bet that he's a dealer (or she) and that it's priced for the market. Which is still likely a lot less than a new one (if you could get one).
If you do need to get it serviced the good thing is that they will refinish the case and bracelet. And the bezel looks to be in pretty good shape so that shouldn't need to be replaced.
