How to set the time, 24-hour hand and date

The watch is provided with a date function and is so designed that the date changes once every 24 hours.
It also is provided with a 24-hour hand. When using it as a 24-hour hand, it can be used to check whether the displayed time is AM or PM.
When using the hand for dual time display (indicating the time of two different regions), pull out the crown to the second click, turn the crown to advance the hand and be sure that AM/PM is set correctly as the date changes.

The date changes around 12 o’clock midnight. Therefore, if the time is not properly set with regard to AM/PM, the date will change at 12 o’clock noon.

To carry out the procedure, please make sure that the watch is in working state. Please wind the mainspring when the watch is not working.

The date is linked to the time and changes once every 24 hours, whether the watch is running or the crown is used to adjust the time. When the time is advanced across a day, the date is also advanced. Even when the time is set back across a day, the date will not be set back.

When the watch is running, the date changes at around midnight (between 11:45 PM and 0:30 AM).

When the crown is used to adjust the time, the date changes between 9:00 PM and 3:00 AM of the next day. The date will then change at around midnight (between 11:45 PM and 0:30 AM) when the watch is running normally.

When setting the time between 9:00 PM and 3:00 AM the next day, first set the time back before 9:00 PM (or ahead of 3:00 AM) and make sure that the date is correct before setting the time.

When the time is advanced or set back to between 9:00 PM and 3:00 AM the next day, the date may not change at around midnight. However, the date will change to the day after the date at 9:00 PM (i.e., the date at 3:00 AM) after 3:00 AM. Also, when the watch is running, the timing at which the date changes will return to the normal timing.

It is necessary to adjust the date at the end of February and 30-day months.

Ex.) To adjust the date in the A.M. period on the first day of a month following a 30-day month

The watch displays “31” instead of “1.” Pull out the crown to the first click.

Turn the crown counterclockwise to set the date to “1” and then push the crown back in to the normal position.
