I always get a kick out of learning something new in the world of horology. While I’m very familiar with quartz and mechanical watches, there are still some movements out there that remain a bit of a mystery. The original Bulova Accutron tuning fork is a perfect example, and in the video below I take a quick look at another interesting, and relatively rare movement.
Prior to the general availability of quartz watches, there were several forms of “electronic watches” in which the traditional balance wheel and hairspring were powered not by a mainspring, but by some form of electrical impulse. The tuning fork by Bulova was just such a movement. Along with the tuning fork, other forms of electronic movements included the fixed coil, the moving coil, and finally, the transistorized movement. This Stellaris is just such a watch. Enjoy the video.
