Precautions on time zone adjustment

If the time zone is adjusted near a time zone boundary, the time of the adjacent time zone may be displayed.

In some areas the boundaries observed by the watch may not exactly correlate to the actual time zone markers on

the land. This does not indicate a malfunction. In this case, set the time zone in the manual time zone setting mode.

When the time zone is adjusted while traveling on land, avoid time zone boundaries to carr y out time zone

adjustment in the representative cities in the time zone whenever possible. In addition, when the watch is used near

time zone boundaries, make sure to check the time zone setting, and manually set the time zone as necessary.

How to adjust the time zone

Continue to press Button B (6 sec),

and then release it when the second

hand moves to the 30-sec position.

Depending on the area, Daylight Saving Time (DST) is individually set.
Daylight Saving Time means summer time, which is a system to lengthen
daylight time by advancing 1 hour when daylight time is long in summer. Daylight saving time has been
adopted in about 80 countries, mainly in Europe and North America. The adoption and duration of daylight
saving time vary depending on the country.
