I finally got a Rolex!. Now what?

[Seminoleman]

hi, I am new here so if I ask a silly question please forgive me. I finally got a Rolex. It appears to be a model 1675. The 16870## serial number I believe dates it in the mid 60's. It came without a band. The band I put on it is not real. Here is my first question. Will any Rolex band do or should I look for a specific model number from that time period? If so, which one? I am attempting to upload a picture or two and hope I am able to do so. Does everything look correct on it? Is it taboo to replace the original bezel with an aftermarket one? I appreciate your responses and feedback and any information you can provide on the watch. Thank you
