While I was on a dive trip in North Carolina, I met up with one of the other divers, Marty, later in the day and noticed that he was wearing a Sub. When I looked at it closer, I saw that the "Submariner" was in red on the dial, and the WR limits were much lower than new Subs. Marty told me that he had purchased the watch new in the early '70s as a gift to himself when he started his career. He doesn't dive with it, strictly a dress watch. I had heard of these Subs, and the Sea Dwellers before, but never had the chance to actually see one. Marty didn't know that the watch was fairly rare until I told him. He said that he never had a reason to send the Sub to Rolex for service, so it's all original. I advised him that if it needed service, he would probably be better off finding a local watchmaker that works on Rolexs so the dial didn't get replaced.
Can any of you all tell me how rare these Subs are? I've never seen one for sale, so I couldn't give Marty any real idea of it's value, but I told him to hang on to it!
