Abstract

PURPOSE:To make it unnecessary to operate the summer time correction by storing the information of the beginning data of the summer time in advance in the watch so that the time may automatically compensated at the time beginning data. CONSTITUTION:The information of the summer time beginning data is set in response to the setting signals from a switch control unit 8 and stored in a data storage unit 10. The summer time ending data is set in response to the setting signals c and stored in another data storage unit 11. These setting operations are carried out by operating an input switch 7 through a display change-over circit 4 while observing the displayed contents of the display unit 5. A summer time control unit 9 compares the contents of the data storage units 10 and 11 with the data information from a date counting unit 6. In the case of coincidence, correcting signals are fed to a time counting unit 3 to automatically correct the time information to the summer time.
