Title: Electronic watch with means for producing pulse sound at selected intervals

Abstract: An electronic watch having chronograph performance is provided with a pulse sound generator for generating a pulse sound at a predetermined interval. The pulse sound generator comprises a counter for counting predetermined clock pulses received from the frequency dividing circuit of the watch, a memory for memorizing a predetermined time interval, manually operable means for selecting the time interval memorized by the memory, a coincidence circuit for detecting coincidence between the contents of the counter and the time interval memorized by the memory and a pulse sound generating circuit for generating a pulse sound when such coincidence occurs.
