B. Functions of the Solar Power Watch
If the charge becomes insufficient, a warning function will operate and the display changes, as
below.
■ Insufficient Charge Warning Function
This feature indicates that the watch has
become insufficiently charged when the sec-
ond hand changes from 1-second interval
movement to 2-second interval movement.
Even in such a case, the watch keeps correct
time, but about 4 days after two-second interval
movement begins, the watch will stop.
After exposing the watch to light, recharging
takes place and the watch returns to one-second
interval movement.
■ Quick Start Function
The watch will stop if it is completely discharged.
It will begin to operate soon after (within 10 second) it is exposed to light.
(However, the time to start may vary according to the brightness of the light.)
■ Overcharging Prevention Function
When the secondary battery becomes fully charged as result of light shining into the watch dial
(solar cell), the over charge prevention feature is activated automatically to prevent the sec-
ondary battery from being charged further. This prevents the secondary battery as well as time-
keeping accuracy, functions and performance of the watch from deteriorating no matter how
much the watch is charged.
If sufficiently charged and time is set.
