Abstract

A digital display type electronic watch having a stopwatch function and comprising a display adapted for selective indication by the common display of horological information in a normal operation mode and chronometrical information in a stopwatch mode, characterized in that a corner for counting the clock pulses for measuring time in the stopwatch mode is divided into two groups for the more and less significant digit portions of the chronometrical information, a gate is provided for selectively and sequentially applying the said more and less significant digit portions of the chronometrical information to the display in the stopwatch mode, and a control signal generator is provided such that a first and second operations of a switch defines initiation and termination of the counting operation by said counter, a further operation of the switch triggers a timer providing an output for a predetermined time period which output is applied to said gate, whereby the gate is switched such that the displayed portion of said more and less significant portions of said chronometrical information is changed, and a further operation of the switch only when the output is obtained from the timer generates a clear signal of the said counter, whereby chronometrical information of a larger value can be displayed to the order of hour without increasing the number of digit positions in the display, while repetitive operations of a single switch enable various operation states in the stopwatch mode.
