In need of second opinion on this 16760

[omar-rye]

Hi there, I'm planning to check out a 1985 GMT 16760 tomorrow and want to gather some second opinions in case I've overlooked anything. The serial number is 84*****. It features an open 6 & 9 date wheel and a gloss dial. The clasp is 62510h, and the end links are 501. I’m still waiting to get the date code on the clasp. While I haven't seen many photos, I'll be viewing it in person tomorrow. According to the seller, it has never been polished and received a service 8 years ago by an independent. Given the limited information, what would be a fair price for this piece? It’s watch only. Thanks in advance
