Omega Geneve cal. 565. Worth it???

Hello everyone, first of all, thank you very much for your help, anything you can share will be of great help. I found this omega geneve cal. 565. Listed for about 350 dollars. I know the bracelet and the crown are not original, but besides that I don’t se much problems with it. Seller told me that it had it’s last service about two years ago. As far as I can see it has not been polished and the dial look good. I would like to know if it’s worth purchasing, since this would be my first omega, and as a matter of fact, my first vintage watch. Thank you very much for all your help!!! 😀
