Insufficient Charge Warning Function
When the watch is insufficiently charged, the
second hand begins moving at 2-second
intervals to notify you that the watch charge is
insufficient.
Although the watch keeps accurate time during
this period, the watch will stop completely if
operation with an insufficient charge continues
for approximately three or more days. Restore
the 1-second interval movement of the second
hand by subjecting the watch to light so that it
recharges. To use the watch with complete
peace of mind, be sure to fully recharge the
battery even after the second hand returns to the 1-second interval movement.
Although the watch can be started again by subjecting it to light after it stops due
to insufficient charge, the time given will no longer be correct, so be sure to fully
charge the battery and adjust to the correct time.
Overcharging Prevention Function
No matter how much the watch is charged, it will not affect the secondary battery,
timekeeping, functions or performance of the watch.
When the secondary battery becomes fully charged by exposing the watch face to
light, the overcharging prevention function is automatically activated to prevent the
battery from being charged further.
Quick Start
The watch stops if there is absolutely no charge. Subject the watch to light and the
hands will start moving in about 10 seconds. (The time required for the hands to
begin moving varies depending on the model and brightness of the light.)
Note, however, that the watch will stop again if the light is blocked at this time
because the charge may still be insufficient.
