Features

This is a GPS solar
This watch has the following features.
GPS signal reception
This watch can be set to the precise
local time by just one button operation
anywhere in the world.
DST (Daylight Saving Time) is reflected
in the time that appears.
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.
When the region or time
zone where the watch is
used is changed, please
carry out operation of
"time zone adjustment."
 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.
Standard Charging Time
GPS signal reception consumes a lot of energy. It is necessary to charge the watch by exposing it to light so
that the indicator hand points to the "middle" or "full" position. (If the charging status is displayed as "low," the
reception will not start even with manual GPS signal reception.)

The figures of "Time required for charging the watch to start moving at one-second intervals" are estimations of time required to charge the stopped watch by
exposing it to light until it moves at steady one-second intervals. Even if the watch is partially charged for a shorter period, the watch will resume one-second-
interval movement. However, it may shortly return to two-second-interval movement. Use the charging time in this column as a rough guide for sufficient charging
time.
The required charging time slightly varies depending on the design and the dial color of the watch.

Solar charging Function
This watch operates by solar charging.
Expose the dial to light to charge the watch.
Once fully charged, the watch runs for
approximately 6 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.

Automatic time adjustment function
This watch automatically adjusts the time in
accordance with action patterns during use.
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.

unable to receive
GPS signals
when the energy
stored in the
watch is low.
