World Time Mode

Troubleshooting
Hand Movement and Indications
The time indicated by the hands is different from the digital time.
This could indicate that the watch has been exposed to magnetism or strong
impact, which has caused problems with proper hand alignment. Adjust the watch’s
hand home position alignment (page E-41).
Time Setting
The current time setting is off by hours.
Your Home City setting may be wrong (page E-18). Check your Home City setting and
correct it, if necessary.
The current time setting is off by one hour.
You may need to change your Home City’s standard time/daylight saving time
(DST) setting. Use the procedure under “Adjusting the Digital Time and Date
Settings” (page E-21) to change the standard time/daylight saving time (DST) setting.
