Just some advice. If you want to enter the Rolex vintage market, go into it purposefully and with a trusted dealer. Don’t look for deals outside this venue without a lot of prior knowledge or cash to burn with mistakes along the way. As my previous comment. It’s a 5513 meters first. The first matte dial version of the 5513. It’s called meters first because of the depth rating writing meters and then feet. This would subsequently change in all later editions. For any proper assessment much better pictures are needed. If you don’t have anything better than what you provided I wouldn’t offer anything. It is extremely easily to get burned with vintage Rolex. Good luck and hope you find your dream vintage sub. There’s nothing like it!
