If the second hand of the watch is moving in 2-second interval movement or has stopped
due to undercharging, recharge the watch either by exposing the solar cell to light or by
swinging.
A. Charging by Exposing the Solar Cell to Light
* Expose the surface of the solar cell to a fluorescent lamp, incandescent light or sunlight
to recharge.
* If the watch is ordinarily concealed from the light as a result of wearing long sleeve
shirts and so on, the watch will be susceptible to becoming undercharged as a result of
not being exposed to light. Try to place the watch in as bright a location as possible
when it is not worn.
* When there are few opportunities for exposing the watch to light, the watch can also be
recharged by swinging in the manner described below.
[Precautions When Charging by Exposing to Light]
* Avoid charging the watch at high temperatures (approx. 60
°
C/140
°
F and above) since
allowing the watch to become overheated during charging can lead to a malfunction.
