Is this Bulova a worthwile purchase?

I recently found a Bulova Gold Computron 1970s (I believe 1974 and thats what the guy said aswell it was.) It has no damage whatsoever from what I can see and works perfectly. They are asking $200 and looked around and saw a few of the same/similar models being sold for anywhere from $300-$600+. Is it a good price? (I wasn't able to get a pic of it but found one online to add)
