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.

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.
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.
Automatic time adjustment function
This watch automatically adjusts the time in
accordance with action patterns during use.
When the watch has sensed suf ficient 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.
This watch is
unable to receive
GPS signals
when the energy
stored in the
watch is low.
