Nothing appears fake to me. Bracelet is pretty worn, but it is an otherwise reasonably nice watch for $250. You won't make any money reselling it if that is what you're after, but if you just want a nice watch to wear, this would do the trick.
Genuine, and if you like it then I can't see a problem with buying it.
Just be aware of issues trying to get replacement parts for a quartz movement nearly fifty years old.
