With rapid popularization of quartz watches, the market is now demanding more elegantly-designed, easy-to-use quartz watches equipped with more useful functions. To meet this, we have developed and released analog tyre Riquartz 510 which indicates hours-minutes only, featuring the use of push button system instead of stem/crowh, thus providing the simplicity in manipulations as digital types. This paper describes the lower power consumption realized dy ond minute step- movement, train wheels mechanism which prevents the displacement of hands possibly caused by shock and the electronic circuit relevant to the electronic hand-setting.
