DateJust MOP - 1991

[sumitd]

Hello! I'm new to the forums. Great to be here!

I have a value/model question:
Before anyone gets upset, I read the "Valuations" sticky :)

My mom came across a Rolex MOP from 1991 at a local jewelry store. I think she got a decent deal on it but unsure because I can't seem to pin down the band on the watch. They said it was original and sure seems like it but... just can't seem to find anything like it on C24 or anywhere online. Hoping some EXPERTS here might be able to shed some light for me.

Also, if any Houstonian's here have an appraiser you recommend locally, please let me know.

Thanks!
