Filed: 1980-05-23
Abstract: An electronic timepiece has a liquid crystal display device in which a plurality of liquid crystal display elements each in the shape of a time-indicating hand are radially arrayed and the liquid crystal display elements are selectively turned on responsive to time-divided time information. A set of counters produce the time data only during time adjustment when the contents in the counters are adjusted, predetermined time units of the time data are selected extending over a longer time than other remaining time units so that there is obtained a larger effective value of voltage to be applied to the liquid crystal display elements in comparison with the case of non-adjustment so that even if the time adjustment is quickly made, one may recognize a display portion which is sequentially turned on in response to the time data.
