A dual display timepiece employs a stepping motor capable of rotation in one sense for driving hour and minute hands in an analogue display and an electronic digital display for displaying other information (second, date, chronograph, etc.). In order to facilitate hour hand corrections a logic circuit is provided which permits the user to enter the nature (positive or negative) and the amount of correction desired into the digital display. Following such entry the hour hand is corrected automatically by application of NxY higher than normal frequency signals to the analogue display, where N corresponds to the number of signals required to effect a one hour or half hour correction and Y corresponds to the correction entered by the user. |
