Abstract

1361230 Electronic watches SUWA SEIKOSHA K K 21 July 1971 [27 July 1970 10 Sept 1970] 51935/73 Divided out of 1361229 Heading G3T In an electric watch having a quartz crystal oscillator 600 driving a pulse or stepping motor via frequency dividing circuitry, the motor coil 113a, stator 113b, c and rotor 114 are arranged in a plane parallel to movement plate 200 and within the area of the plate, which also carries the oscillator and dividing circuitry 900 and the watch train. The watch is generally as in Specification 1361229.
