PURPOSE:To improve the use of the multiple functions of a watch by adding the function selection by the operating times of a switch and the control function of the operating time of the switch. CONSTITUTION:A case 1 is equipped with a digital display unit 2, an alarm speaker unit 3, a fuction selecting mode switch 4 and an alarm time setting switch 5. A fundamental time mode 31 and a stop watch mode 32, which are normally frequently used, constitute one group. By the operations of the mode switch 4, return is made from the mode 32 directly to the mode 31. The group selection of seldom use is performed by turning on the switch 4 for a preset period in the mode 31 or 32. By the subsequent operation of the switch 4, a time correcting mode 34 is selected to restore the fundamental watch in response to the subsequent operation. |
