Abstract

PURPOSE:To diversify functions by providing an automatic summer time correcting mechanism to a composite analog and digital electronic watch. CONSTITUTION:The dates for the start and end of execution of summer time are detected from the period having been stored in a summer time period storage circuit 8 from the outside, and the data of a year-month-date storage control circuit 6 and an automatic day decision circuit 7, and at the suitable time, the basic clock in a clock circuit is corrected by the data of a summer time correction value storage control circuit 9; at the same time, a signal is fed to an analog display device electric correcting circuit 5, by which the indication time of an analog display device is corrected. Thereby, the automatic summer time correction of the composite analog and digital electronic watch is made possible, and it is made effective at the time of executing summer time.
