Abstract

PURPOSE:To avoid the inconvenience and misuse of watches from being caused, by the constitution that the function of a watch is stopped, if the watch is disassembled after shipment, such as opened external case except for battery charging part. CONSTITUTION:The switch 9 is operated with the open operation of the external case 3 to reset a given memory of the nonvolatile memory circuit 17 provided in the watch circuit and to stop the function of the watch. For example, if the case 3 is slided, the projection 10 is latched with the elastic part 7a of the member 7 and the member 7 is shifted left accompanied with the shift left of the projection 10. The conductive film 8 is in contact with the electrodes 9a, 9b to open the switch 9. With the closing of the switch 9, output ''1'' is produced and the memory of the nonvolatile memory circuit 17 is reset via the write-in circuit 16, and the output is at ''0'' to reset the count circuit 13. Thus, the function of watch can be stopped.
