Abstract
PURPOSE:To make the operation of a multifunctional watch easy and sure by letting counters offer combination use selectively for counting of plural functions and displaying the selected functions. CONSTITUTION:According to the operation times of a function selection switch S4 in which 4 times are 1 cycle, the T type FFs 49, 50 of a function selection circuit 48 perform counting subsequently. Then, only the bits corresponding to the functions of the time display NO, alarm AL, timer TI, chronograph CH selected from the NOR gates 51 thru 54 of the circuit 48 become high level and the binary contol signals corresponding to the selected functions are generated. If displaying, etc. corresponding to the counters of combined use controlled by logic circuits formed of gates, etc. are performed by these control signals, the multifunctional watch containing alarm, timer, chronograph, etc. as well may be readily and surely operated without any mis-operation.
