About charging
How to charge the watch
Expose the dial to light to charge the watch.
To ensure optimal performance of the watch,
make sure that the watch is kept sufficiently
charged at all times.
Under the following situations, the energy of
the watch is likely to be depleted, resulting in
stoppage of the watch:
•
The watch is concealed under a sleeve.
•
The watch is used or stored under
conditions where it cannot be exposed to
light for a long time.
* When charging the watch, make sure that the watch is not heated to a high temperature. (The operational
temperature range is between -10°C to +60°C (14 ºF and 140 ºF).)
* When first using the watch or starting to use the watch after it has stopped because of the energy depletion,
sufficiently charge the watch referring to the table on the page at the right.
Standard Charging Time
Charge the watch using the times below as a guide.
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 model.
