PURPOSE:To eliminate the need for external manipulation and to prevent the occurrence of a malfunction, by performing an automatic all-clear at a time when a watch is assembled. CONSTITUTION:A plus terminal 5 is pressed by a back 7 in the middle of setting the back 7, and makes contact witha switch-on clear pattern 3a3 formed on a substrate 3 to perform an all-clear. Through the further pushing-in of the back 7, the plus terminal 5 is further pressed by the back 7, and as a result, it passes through the switch-on clear pattern 3a3. This causes starting of a watch from a preset condition. |
