Bulova introduced the Accutron tuning fork electronic watch in 1960 and it was extremely popular in many iterations throughout the sixties and into the early seventies. This technology (electronic tuning fork) was “cutting edge” and the story makes for great reading. The “Spaceview” version came about by happenstance after consumers expressed strong interest in purchasing Bulova retailer demo watches that showed the actual tuning fork movement. Great horological history.
