HOW TO CHARGE AND START THE WATCH
When you start the watch
or when the energy in the
rechargeable battery is
reduced to an extremely
low level, charge it
sufficiently by exposing
the watch to light.

NOTE
It is not necessary to charge the watch
fully. It is important, however, to charge
the watch sufficiently, especially in
case of initial charge.

The above table provides only general guidelines.
<Reference>
Condition A: Time required for full charge
Condition B :
Time required for steady operation
Condition C:
Time required for 1 day’s charge
k The values in this column represent the
charging times required until the second
hand moves constantly at 1-second
intervals after the watch starts operating
with the second hand moving at 2-second
intervals.
Even if the watch is not charged for the
time specified in the column, the second
hand may temporarily move at 1-second
intervals. But it will soon resume moving
at 2-second intervals, and therefore,
charge the watch for more than the
specified period.
When the watch is fully charged, it will
continue to operate for about 4 months.
When charging the watch, do not
place it too close to a hot light source
such as a photo flash light, spotlight or
incandescent light as this can greatly
raise the watch temperature.
When charging the watch by sunlight,
do not leave it exposed to the sun for a
long time, on the dashboard of a car,
etc. as this can greatly raise the watch
temperature.
Make sure the watch temperature does
not exceed 50°C while charging, to
avoid damage to the parts inside.
