Charging the Watch
The charging cable can be used to charge the
watch. The watch can also be charged by
sunlight or other light, in addition to electrical
power.
Charging with the Charger Cable
Charging with the charger cable is faster than
solar charging.
Important!
Use only the supplied charger cable for
●
charging.
A device with a USB port (Type-A) can
●
also be used for charging.
Note that no guarantees are made
●
concerning the suitability of all types of
USB ports for charging. If charging is
not possible for some reason,
disconnection from the USB port is
recommended.
Place the charger on a desk or other
●
stable surface, making sure there is
plenty of open space around it.
Charging with the charger and watch in
a bag or some other enclosed space
can cause overheating of the watch.
Should water or any other liquid get
●
onto the watch or charger cable during
charging, immediately unplug the
charger cable from the power source.
Perform charging in an environment
●
where ambient temperature is
between 5 °C and 35 °C (41 °F and
95 °F).
Avoid pinching your hands or fingers in
●
the gap of the clip of the charging
cable.

Precautions When Charging
●
A charging operation will not start while the
●
battery level indicator shows
prolong the life of the watch's rechargeable
battery, charge only while the battery level
indicator shows or lower.
Do not attempt charging at high ambient
●
temperatures of 35 °C (95 °F) or greater.
The watch becomes hot during charging,
which can cause charging to stop
automatically. High ambient temperature
may result in a less than full charge.
Operation on a custom computer or a
●
computer that has been modified from its
original configuration is not guaranteed.
The watch may become warm during
●
charging. This is normal and does not
indicate malfunction.
Note
Starting from a blank display, it takes
●
about 3.2 hours to achieve a full
charge.
Charging time depends on ambient
●
temperature and other factors.
