1. FEATURES
This is a solar power analog quartz watch with a
solar cell incorporated in its dial.
We recommend that you first read these
instructions.
2. BEFORE USING
A secondary battery is used in this watch to store
electrical energy. This secondary battery is a
clean energy battery which does not use any
toxic substances such as mercury. Once fully
charged, the watch will continue to run for about
six months without further charging.
How to use the solar power watch well
To use this watch comfortably, make sure that the
watch is always recharged before it stops.
There is concern of overcharging this watch.
(Overcharging Prevention Feature) we recommend
that you recharge the watch every day.
Before using, expose to light and make sure
the watch is sufficiently charged.
See “9. TIME REQUIRED FOR CHARGE” for
charging time reference.

3. FUNCTIONS OF SOLAR POWERED WATCH
These functions are only found in the solar power
watch. If the watch becomes insufficiently charged,
a warning comes into operation and the display
changes, as below.
Quick Start Feature
The watch will stop if it is completely discharged.
It will begin to operate soon after it is exposed
to light.
(However, the time it takes to start may vary
according to the brightness of the light.)
Please note that if the light is blocked the watch
might stop again as a result of being insufficiently
recharged.
Overcharging Prevention Feature
You can recharge without worry
Once the secondary battery is fully recharged, the
overcharging prevention feature comes into
operation and prevents further recharging, so that
the secondary battery is not overcharged.
Insufficient Recharging Warning Feature
The second hand changes to two-second
interval movement to indicate insufficient
recharging.
Even in such a case, the watch keeps the correct
time, but if about 3 days pass after the two-second
interval movement begins, the watch stops operating.
After exposing the watch to light, recharging takes
place and the watch returns to one-second interval
movement.
Time Setting Indication Feature
If the watch stops, subsequent exposure to light
allows the ‘quick start’ function to start again, and
the second hand moves with a hitch movement
to indicate that the time is incorrect.
In this case, quickly recharge the watch and reset
the time.
Otherwise hitch movement will continue.
4. SETTING THE TIME AND CALENDAR
Setting the time
1. Stop the second hand at the 0 second position by
pulling out the crown to the 2nd click.
2. Turn the crown to set the time.
3. After setting the time, firmly push the crown back
in to the normal position.
Setting the date
1. Pull the crown out to the 1st click.
2. Set the desired date by turning the crown.
• If you adjust the date when the watch display is
reading between 9:00 pm and 1:00 am, the date
might not change on the following day.
After you have set the calendar, be sure to firmly
return the crown to its normal position.
5. WHEN THE SECOND HAND MOVEMENT IS
ABNORMAL
Two-second interval movement
Insufficient recharging warning feature is working.
Recharge the watch by quickly exposing it to
light until it has returned to one-second interval
movement.
During two-second interval movement, the watch
continues to keep the correct time.
If two-second interval movement continues for about
3 days, the watch stops.
Hitch movement
Time setting indication feature is working.
Quickly expose the solar cell to light in order to
recharge it, then reset to the correct time.
