CAUTION
Do not adjust the date when the time the watch indicates between 9:00 p.m. and 1:00 a.m.
If the date is adjusted in this condition, the date may not change properly the following day, or a malfunction may occur.
If you set the date when the time the watch indicates between 9:00 p.m. and 1:00 a.m., pull out the crown to the second click, and turn it counterclockwise (6 o’clock direction) to advance the hour hand until it passes 1:00 a.m. temporarily, and then set the date.

Therefore, if the a.m./p.m. is incorrectly set, the date will change around 12:00 p.m.

Tips for more accurate time setting
To ensure effective operation of the Spring Drive mechanism, observe the following instructions when you set the time.
-
Before setting the time, make sure to wind the mainspring sufficiently.
-
When starting to use a watch after it stops, wind the mainspring sufficiently. To set the time after that, wait for approximately 30 seconds after the seconds hand starts moving, then pull the crown out to the second click.
-
The seconds hand will stop moving when the crown is pulled out to the second click. Do not stop the movement of the seconds hand for longer than 30 minutes. If the stoppage of the seconds hand movement exceeds 30 minutes, push the crown back in, and wait for approximately 30 seconds after the seconds hand restarts moving, and then set the time.
(Ensure that the power reserve indicator is showing a fully wound state.)
