PURPOSE:To enable watch to be used over a wide range as a full-fledged time measurement system by so performing combinations of functions that three functions of time counting function, stopwatch function and remaining time measuring function operate mutually independently. CONSTITUTION:The respective modes consisting of a time mode 3a having functions of measuring the times such as the hour, minute, second, month, date, day, a stopeatch mode 3b having a stopwatch function and a timer mode 3c having a function of measuring remaining time are cyclically changed over in the order of 3a 3b 3c 3a at every one push of a button 2a. The three functions 3a, 3b, 3c are independently operated by operating the three buttons 2a thrn 2c so that the remaining time measuring function may be independently used even while the stopwatch function is being used and that the stopwatch function may be independently used even while the remaining time measuring function is being used. |
