Class G04C : ELECTROMECHANICAL CLOCKS OR WATCHES
Subclass 3/08: Electromechanical clocks or watches independent of other time-pieces and in which the movement is maintained by electric means (clocks driven by synchronous motors G04C 15/00) wherein movement is regulated by a mechanical oscillator other than a pendulum or balance, e.g. by a tuning fork
