The movement is an 861 so fairly bombproof but at almost 50 years old will need a service unless you buy one which has already had one recently.
The rest is, I think, down to what you want. A totally restored looks like new version or something extremely battered that you buy cheaper and then have restored to a level that you can enjoy. Or anything in between.
Whatever you decide make friends with a local trusted watchmaker and take it along for an assessment before you decide what you want to do with it and how much you want to spend. Remember that if you replace dial, hands, glass and pushers keep the originals in case you want to change back in the future.
