116610LN Authenticity Verification

[RedRocketBoi]

There is a sub for sale on reddit and there doesn't seem to be any immediate red flags at first but want to get some second thoughts before anything goes through. It is a private seller out of Chicago and is giving a pretty good deal on it. Seems like a straight guy with no tricks or anything and agreed to paypal for buyers protection and insured shipping. The watch is a bit beat up but nothing a clean up can't do. He also emailed me a copy of a warranty receipt from rolex this summer and says box and papers are included with the sale.

I have attached the photos from his post and a photo he posted about two years ago on his reddit account of the same watch. Is there any thing that throws a red flag that I didn't catch? Also a bit new to second hand purchases so is there any way to get it verified by someone after purchasing it?
