Abstract

1383526 Electronic timepieces SUWA SEIKOSHA KK 2 March 1972 [3 March 1971] 29727/74 Divided out of 1383525 Heading G3T The Specification describes an electronic timepiece with an oscillator driving a stepping motor as in Specification 1383525 but the claims relate to the use of a switch and a stem such that, when the stem is pulled out, the timepiece is stopped indicating an even number of seconds, and when the stem is pushed in, the seconds hand is caused to advance after an interval of one second.
