In reply to The the watch is dated 1970,… by mybulova_admin
This is what I wrote, "that is why I called it a transition watch, on the cusp of the time period between the majority of self winding and the majority of battery operated Bulova watches,"
From what I read here about the Accutron concept in 1960, was a change in the mechanism of the movement, based on the tuning fork sensor, no longer a spring and a jeweled one. It does not say that a battery operated quartz movement was involved.
The first retail quartz movement with battery watch was produced by Seiko in 1969, called the Seiko Quartz Astron 35SQ, during a highly competitive period between the top watch makers in the world.
The information I am getting is confusing me.
