1987 GMT Master 16750 any red flags?

I have been offered this Rolex GMT Master by a dealer. He says it is a 1987 16750 with its original warranty card but no box. He says it was recently serviced. I have asked for documentation stating as such.
I have checked this site and the internet to check the validity of this watch but I know very little about vintage Rolex models. He has not shown me a movement picture. I have seen the watch in person and it looks correct to my inexperienced eye. The white lume on the indices matches the lume on the hands. The bracelet appears to be correct and tight with 50 on the last link and 550 on the end. The back of the clasp is 62510H Steelinox Registered Swiss Made with 06 above the number. He says he has more links for the bracelet. The hands seem to be stacked properly. Crystal appears to be original. Bezel looks good. Not sure if there has been any polishing.
He is asking $10500 negotiable.
I’m asking for help validating this watch. Is the dial correct along with the hands? Are there any red flags that would prevent me from buying? I don’t own a Rolex and I’m considering it for myself. The seller appears to be honest and reliable. I can pay for and pick up the watch in person.
Any help or guidance would be greatly appreciated thanks
Pictures some taken in bright sunlight inside my car. I’ve asked for more including one showing the inside of the bracelet

IMO it’s over polished and for that price (or just a tad higher) there are better options. Look at the lug holes on this one and yours. Also, I’m surprised a dealer would let you take a watch to your car. They definitely wouldn’t do that around here

Thanks for your reply and insights.
Much appreciated

This would make me crazy. The spring bars look like they’re about to jump out of the case. Also I know you mentioned “warranty card” but that would be a service warranty. The original sales warranty would have been a paper certificate. Not a huge deal but it doesn’t add any value like the original warranty paperwork might

Thanks for all the help
I’ll pass on this GMT. I’d really prefer a no date vintage Submariner anyway so I’ll keep casually looking

They are probably not original Rolex spring bars which might add to the illusion of over polish when looking at the case hole depth between both examples.

Way overpolished and really heavy worn. Best decision to leave it out.

Very nice collection. Thanks for sharing
And thanks to all above who commented and offered expertise to a novice Rolex buyer. I was close to making an offer on this watch until you all “showed me the light”

Curious about timegrapher readings, too.

Don't overlook the sea dweller as well. Given the rarity, difference in original retail price and current relative pricing to the submariner, it seems like a relative bargain to me. Relatively, not absolutely that is. 😀

Be careful out there with vintage rolex, specially with cases and casebacks.
