Feedback on a GMT 16750 I'm looking at.

[jpo]

I humbly request the thoughts of the fora on a 16750 that I am looking at. I currently have a 16600, so this would be my first vintage (ish) watch, so I'm a bit new at assessing a vintage with some age on it and would love a little feedback. This 16750 is 1984, glossy dial that has become kind of matte, with a really nice faded bezel, looks to me like a really nice patina on markers and pretty close patina match on the hands.
The acrylic crystal has some swirlies on it, but not sure how big a deal that is (polish or replace i suppose). The bracelet has almost no stretch at all, but bracelet as some desk diver light scratches. Has original box, no papers. Anyway, please let me know your thoughts on this GMT and anything else I might look out for. Pricing will probably get to mid-high $5k.
