Opinions on a vintage Devil Diver?

I'm considering a birthday purchase of a Bulova Accutron Devil Diver and as it's the non-mechanical version I wanted to get some insight on how well these Accutron watches perform/last over time?

The reason I'm interested in the Accutron is because the only watch I have from my late Grandfather is a smaller Accutron (218 I think) but due to its small size, I'll never really wear it. So I figured in his honor I'd get something to complement his.

Thanks in advance OF peeps!

Thanks guys, I didn't realize that there were both a quartz and tuning fork versions. Without the tuning fork I feel that it lacks the connection to my grandfather's old watch, plus if they're difficult to service that might make me reconsider this idea altogether. Advice very much appreciated!
