There were various models Accutron but the most impressive and the most wanted is “spaceview” (this I present to you in pictures), certainly one of the first mass produced watches whose mechanism is visible.ETA also had this type of mechanism (ESA by Bulova patent), which is in addition to many top brands of that time.Leave the "Model Name" dropdown menu blank (do not enter anyting in it), then hit the "apply" button below the "Model Name" dropdown.You'll get three ads, and the thrid is a Spaceview variant "H".gold "Spaceviewed" models in an advertising campaign which was intended to accomplish two things.
It is only the third 218 Spaceview model that I have owned in the 14 years I have been selling vintage watches.
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.
Movement model undertermined....couldn't find when looking with magnifying glass,but that may just be my eyes. The band appears to be also 10k gold based on some small print on the band....
From research I believe it to be a Accutron(based on symbol on the front case, and Spaceview based on the see-thru case showing movement. I believe it says 1/10k g Top Cap USA( that may just be my imagination, but thats what it appears to say.) I searched for any ads that matched the watch and yet to have found one.
