Bulova Accutron (1960)
Bulova Accutron
This was the first wristwatch to keep time using a tuning fork, which was
powered by a one-transistor electronic circuit. In the photo, the tuning fork
is visible at the top, between the two electromagnet coils. The tuning fork
vibrated at 360 Hertz, so the watch emitted a soft hum rather than a ticking sound.

I still have mine I bought in 1970 I believe and used it for many years until I got tired of having to change the battery and switched to a Seiko self winding one for around $300 back around the 1970s, and it was the most accurate watch I ever had!

If you have one these...be careful of the batteries that you buy for it.
