It is AM0: 50 on the 29th of the month, and the date window 21a (calendar date display means) can also be displayed as "29".

FIG. 5 shows the time difference of local time in leap years by +1.
When set to time. Home time is February 28
If the local time is +1 hour at 11:50 PM,
Originally, it is AM0: 50 on February 29, and the date window 21a (calendar date display means) must indicate "29". However, since the local time has only information on the time difference data from the home time, it is March 1st. At 0:00 AM on the day, the date window 21a (calendar date display means) is displayed as "1".

FIG. 6 shows the time difference of local time in a leap year as -1.
When set to time. If the home time is AM0: 50 on March 1 and the local time is -1 hour, it should be PM10: 50 on February 29, and 21a (calendar date display means) should indicate "29". Since the local time has information only on the time difference data from the home time, February 28 PM 10:50 and 21 (a) (calendar date display means) is displayed as "28".

As a means for solving these problems, there is a means for setting the year. However, it is necessary to provide a means for displaying a hand, and if a hand for the year display is provided at the chronograph hand, it becomes difficult to see when the chronograph is displayed. There are also design restrictions.

[0012] An object of the present invention is to set a home time of February 29 in a timepiece which can set February 29 and has no year information.
