Abstract

PURPOSE:To enable the momentarily changing time to be listened and be checked by building in a buzzer circuit. CONSTITUTION:A buzzer 15 for a function of emitting sounds at a fixed interval and set buttons 16, 17 of functions for producing sounds at a fixed interval are additionally provided to an electronic wristwatch having buttons 4, 5 for operating stopwatch. Then, the time standard signal of high accuracy having been produced with a crystal vibrator 22 and oscillation part 23 is divided down with a frequency dividing part 24, after which it drives an A-D converter 25 to display the time in a liquid crystal display body 26. At the same time a buzzer circuit 28 is driven to let the buzzer 15 be sounded at the fixed invertal having beforehand been memorized in an interval set circuit by the set buttons 16, 17.
