Super nice trio but...

Look at the power storage and regulator separately
…and you get this useful way of classifying the various types of movements Spring Drive is quartz regulation X mainspring. Electric watches were balance wheel regulation X battery ...

ACCUTRON A tuning fork watch (Bulova Accutron) uses a unique mechanism that relies on the vibration of a tuning fork to keep time, rather than a traditional balance wheel and hairspring. Introduced in 1960, the Accutron was the first commercially successf...
