Bulova 1977 Accutron Date & Day
Bulova Accutron from 1977; has the 2193.10 movement with day/date feature; stainless steel case; original band/bracelet replaced; luminous hands and dial - rather simple silver-ish dial; caseback dated N7
Looks to match the model 21569 from this 1977 advert.
My first acquisition of an accutron; though it is not the more desirable 218 or 214, still a nice piece; never heard the hum of an accutron before, so that was a cool first experience.
If anyone has any documentation/service manuals for this movement, I would appreciate a pdf copy or a link - thanks!
