Abstract

1293160 Electric timepieces SUWA SIEKOSHA K K 10 Dec 1969 Divided out of 1293159 32548/71 Heading G3T The specification discloses a vibrator for an electric timepiece which is substantially identical to that of Specification 1293159 but the claims relate to the relative disposition of the centre of gravity of the oscillating body and the point of attachment between the body and the spring.
