At the end of 1959, in anticipation of the launch of a revolutionary new line of watches called Accutron, Bulova designers and craftsmen created tooling that imprinted dial markings on some of the new Accutron plastic crystals. The printed crystal carried all of the information that would normally be found on an Accutron dial. This allowed Bulova to eliminate the dial from several models of the new watches and install a printed crystal, thus exposing the tuning fork and the green colored circuitry inside. Because ordinary plated hands didn't provide enough contrast against the movement to be easily seen from a distance, Bulova used white painted luminous handsets as replacements. The converted watches were only intended to be used as sales aids in order to showcase the revolutionary Accutron tuning fork movement.
Watch is fully working. As a curious note when you put these to your ear you will hear the hum of the tuning fork mechanism! It was a whole sensation at the time, a watch from the future...
