This is a GPS* solar watch.
This watch has the following features. ＊GPS is an abbreviation for Global Positioning System.
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.
Expose the dial to light to charge the watch.
Once fully charged, the watch runs for approximately
six months.
This watch quickly adjusts
the time by receiving
GPS signals from GPS
satellites.
This watch responds to
a total of 39 time zones
around the world.
※Unlike navigation equipment, this GPS solar watch is not designed to constantly receive GPS signals from
GPS satellites without any operation.This watch receives GPS signals only in the time zone adjustment mode,
automatic or manual time adjustment mode.

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 tim e zone is adjusted while travelin g on land , avoid t ime zone boundaries t o carry out time zone
adjustment in the representati ve cities in the time zone whenever po ssible. In addition, when the wa tch is used near
time zone boundaries, make sure to chec k the time zone setting, and manuall y set the time zone as necessary.
