The movement is 1964 and the case is 1967, so there is a good possibility that the original movement has been replaced.
I'm looking throuigh the 1967 linebooks for a case and dial match.
Also just so you know there is no such thing as a hidden Spaceview. All Accutron 214's had the same movement (more of less). All Accutrons started out with dials. The Spaceviews came a few years later when Bulova decided to remove the dial to show consumers the inner workings of their new technology. Any 214 Accutron can technically become a Spaceview by removing the dial, however genuine factory issued Speceviews have certain traits that other normal Accutrons may not neccessarily have.
So to clarify, your watch is not an Accutron Spaceview, but a standard Accutron 214 who's model number we will hopefully find for you.
