I still have one I bought for around $125 or 150 in Hawail in 1966.  I'm
sure with a fresh battery it wud still work.. I have the see-thru model.

Bulova, let the name alone... When I was a child a person in the
neighbourhood owned a "BULOVE ACCUTRON" known as the "humming wristwatch".
This was the first (and only?) wristwatch to use a mechanical tuning fork
running at a few hundret Hertz instead of a conventional balance spring.
