G04C3/06 - CPC Classification

Classification description:

Electromechanical clocks or watches independent of other time-pieces and in which the movement is maintained by electric means wherein movement is regulated by a balance using electromagnetic coupling between electric power source and balance

Sub-classes:

G04C3/061 » {the balance controlling contacts and mechanically driving the gear-train} 1
G04C3/062 » {the balance controlling contacts, the gear-train or several gear-trains being driven electro-magnetically thereby} 1
G04C3/063 » {the balance controlling contacts, the balance driving electro-magnet simultaneously driving the gear-train} 1
G04C3/064 » {the balance controlling indirectly, i.e. without mechanical connection, contacts, e.g. by magnetic or optic means} 7
G04C3/065 » {the balance controlling gear-train by means of static switches, e.g. transistor circuits } 2
