About charging
How to charge the watch
Expose the dial to light to charge the watch.
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.
To ensure optimal performance
of the watch, make sure that the
watch is kept sufficiently charged
at all times.
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
(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
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.)
Check the charging status.
P.13
The required charging time slightly varies depending on the design and the dial color of the
watch.
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.
