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.
