This watch can be set to the
precise local time by just one
button operation anywhere in
the world.
This watch operates by solar
charging.
This watch automatically
adjusts the time in accordance
with action patterns during
use.
Expose the dial to light to
charge the watch.
Once fully charged, the watch
runs for approximately six
months.
When the energy stored in the
watch runs out completely, it
takes time to fully charge the
watch, so please keep in mind
to charge the watch regularly.
→ How to charge the watch P.37
→ Standard charging time P.37
When the watch has sensed
sufficient brightness under
an open sky, it automatically
receives GPS signals from GPS
satellites. This function enables
the watch to automatically
adjust the time precisely even
while you are using the watch.
→ Automatic time adjustment P.46
＊This watch is unable to receive
GPS signals when the energy
stored in the watch is low.

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 carry 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.
