Shouldnt matter if its 1 or 40 years old.
Mechanical watches get/need service and then they should be fine. Only if parts arent available it becomes an issue, but I cant imagine that on a '90's tudor. It has an ETA 2824 I think so every jeweler at the streetcorner should be able to service/have parts for it.
When buying an old watch, ask when it was last serviced if known. A reputable dealer services the watch before selling. (depending on what you pay for it of course....)
