How does the Accutron Spaceview work?
I am wondering how the electronic circuit used to drive the tuning fork in the Accutron Spaceview watches worked? The page The Accutron 214 gives a brief explanation and some diagrams. I am most interested in the later "two wire" circuit:
I am unsure whether the tuning fork has magnets inside the cups or if they are just metal, but I believe they are just metal. It would be nice to verify this somehow. Other than that the driving coils keep the fork in motion with periodic pulses of current and that the feedback coil somehow senses the motion of the fork to control the driving coils through the PNP transitior, I am absolutely clueless as to how the circuit works. Any help would be appreciated!
