Amazing Tuning Fork Watch - 1970s Technology
This is a tuning fork watch, yes that’s right a watch that gets its timing from the frequency of a tuning fork!
Technology originated by Bulova in the early 1960s.
The full length video shows me restoring a Citizen Hisonic watch from the 1970s using a Bulova 218 tuning fork movement.
I show how it all works and restore this one back to its former glory.
