Abstract
PURPOSE:To ensure an easy and assured display and the memory setting with no malfunction, by securing the display of the year and month or the memory of the information on the year and month in accordance with the state of the step number of the external operating components such as the setting stem and others and by other external operating components such as the push- button and others. CONSTITUTION:With push of push-button 13 with winding stem 11 set at the 1st position, the drive drive display of pointer 6 varies via month/year discrimination circuit 9, control circuit 15 and month/year display driving circuit 14 each. Thus the month is displayed by the driving frequency of pointer 6 having the 2-second step movement or the like, and then the year display is carried out by the driving frequency of the pointer having the 3-second step movement and in the lowest- rank digit number of the dominical year. Then stem 11 is pulled out to the 2nd position, and manual date correcting mechanism 12 is operated. And push-button 13 is operated at the time point when the numerical value showing the date in the date window becomes equal to the set month. Thus the set month is stored into month/year deciding circuit 9 via control circuit 16. In the same way, the operation is given so that the residue value obtained by dividing the current year by 4 may show the lower-rank digits and that numerical value in the date window may be 20-23. In this way, the year information whether the next year is the leap year or not can also be set and stored in circuit 9 with no malfunction.
