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 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 and +60 °C.)
 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.

About charging

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.

Standard Charging Time
For an approximate time required to charge the watch, refer to the
table below.
GPS signal reception consumes a lot of energy. Keep in mind to charge
the watch by expose to light so that the indicator hand points to the "level
position (middle)" or "F (full). " (If the charging status is displayed as
"E (low), " the reception will not start even with operation of GPS signal
reception.)
 Check the charging status.

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.
