How to use (For models with the date, day of the week, and a 24-hour hand)

This watch is equipped with a date and day of the week display function. The date and day of the week change once every 24 hours.

The date changes around midnight, and the day of the week changes at around 2:30 a.m. If the a.m./p.m. is incorrectly set, the date will change at 12 o’clock noon, and the day of the week will change at around 2:30 p.m.

1. Make sure that the watch is operating.
   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.

【Ex.】

If you want to set the date to “6,” set the date to “5” by turning the crown clockwise.

Turn the crown counterclockwise (6 o’clock direction) to set the date, and turn the crown clockwise (12 o’clock direction) to set the day of the week.

When the day is adjusted by turning the crown clockwise, the mainspring is also wound. This makes turning the crown a little heavy but this is not a malfunction.

It is necessary to adjust the date after February (which has 28 days, 29 days in a leap year) and a 30 day month.

On the first day, “31” is displayed. Pull out the crown to the first click. Turn the crown counterclockwise (6 o’clock direction) to set the date to “1,” and push the crown back into the normal position.

This caliber is equipped with a “time zone adjustment mechanism.” By using the 2 o’clock position crown, the hour hand can be independently adjusted in one-hour increments.

This eliminates the trouble of stopping the watch to adjust the time when you travel abroad.
In addition, by using the 24-hour hand (GMT hand) at the center of the watch, the watch can be used as a dual time watch that shows home time and local time.

1. Check that the 3 o’clock position crown is at its normal position. Then pull out the 2 o’clock position crown to the first click.



2. Turn the 2 o’clock position crown to set the time of your destination.



3. On completing the adjustment of the 24-hour hand, push the 2 o’clock position crown back to its normal position.

After the hour hand has been adjusted to the local time, the 24-hour hand still shows the original time (home time), allowing the watch to be used as a dual time indicator.
