1. BEFORE USING THE WATCH
This is a solar cell analog quartz watch with a solar
cell incorporated in its dial. We recommend that you
first read these instructions. Please expose the
watch to light and recharge before use.
2. ABOUT THE SOLAR CELL WATCH
This watch is powered not by an ordinary battery, but
by converting photo energy to electrical energy.
A secondary battery is used in this watch to store the
converted electrical energy. After being fully recharged
once, the watch can continue to run accurately for
about 60 days without any further recharging.
■ How to use the solar cell watch well
To use this watch comfortably, make sure that the
watch is always recharged before it finally stops.
There is no concern for overcharging this watch,
(Overcharging Prevention Feature) we recomend
that you recharge the watch every day.
■ Replacing the secondary battery
However often the secondary battery is repeatedly
recharged their is no need to replace it like a battery.
But if the secondary battery deteriorates, its
rechargeability might decrease and recharging might
take time. If this happens, please replace the
secondary battery.
2. SPECIAL ADDITIONAL FEATURES OF THE
SOLAR CELL WATCH
These additional featurtes are only found in the solar
cell watch.
■ 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.
■ Overcharge Prevention Function
You can recharge without worry.
Once the secondary battery is fully recharged, the
overcharging prevention feature comes into operation
and prevents over-recharging
■ Insufficient Charge Warning
Feature
The second hand changes to a two
second interval movement to
indicate insufficient recharging.
Even, in such a case, the watch
keeps correct time, but if about 24
hours pass after 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
displayed time is now incorrect.
In this case, quickly recharge the
watch and reset the time.
Otherwise, the 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 the crown out to the 2nd click.
2. Turn the crown to set the time.
3. After setting the time, firmly push the crown back in
to its normal position.
■ Setting the calendar
Adjusting 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
24 hours, 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.
6. MAKE SURE THE WATCH IS CONTINUALLY
RECHARGED
Please note that if you wear long sleeves, the watch
may stop as a result of being hidden and not
exposed to light.
When you take off the watch, try to place it in as
bright a place as possible, and it will always continue
to run properly.
Please note that right after a ‘quick start’ the watch
might stop as a result of insufficent recharging if light
is blocked.
7. CAUTION WHEN RECHARGING
The watch will be damaged during recharging if it
gets too hot (about 60C/140F or more). Avoid
recharging at high temperatures.
8. CAUTION
Under no circumstances use an ordinary battery.
A secondary battery is used in this watch to store the
electrical energy which has been converted from
photo energy.
The watch has been designed so that it will not
operate if the battery is inserted instead of the
secondary battery. However, if a battery is used, and
if is recharged, it will become overcharged and there
will be a danger of the battery exploding
Under no circumstances use a secondary battery
other than the designated type.
9. TIME REQUIRED FOR RECHARGE
Time required for recharge may vary according to the
design (colour of the dial, etc.) and operating
environment. The following table will serve you as a
rough reference.
*Daily recharging time – the recharging time required
for the watch to run on one-second interval
movement for one day
*Full recharging time – the time from when the watch
is stopped to when it is fully recharged.
10. PRECAUTIONS
1. Avoid temperature extremes
Avoid leaving your watch in extremely warm or cold
locations for long periods of time.
• This may cause your watch to gain or lose time and
affect its other function.
• Place your watch on your wrist to restore its original
accuracy should it begin to lose or gain time.
2. Avoid strong shock
This watch will withstand the bumps and jars
normally incurred while playing and during sports
activities.
Avoid dropping your watch on the ground or
subjecting the watch to severe shock which may
cause malfunction or damage.

3. Resistance to water
Check the chart to determine the water resistant
properties of this watch.
4. Avoid strong magnetic fields
Keep your watch out of the immediate vicinity of
strong magnets. Generally, your watch is not affected
by magnetic fields from such household appliances
as television sets and stereo equipment.
5. Static electricity
The integrated circuits used in the watch are
sensitive to static electricity. If exposed to intense
static electricity, the watch’s display may lose its
accuracy.
6. Avoid harmful chemicals, solvents and gases
Avoid wearing your watch in the presence of strong
chemicals, solvents and gases. If your watch comes
in contact with materials such as gasoline, benzine,
paint thinner, alcohol, spray cosmetics, nail polish,
nail polish remover, adhesives or paint,
discolouration, deterioration or damage to the case,
band, and other components may occur.
7. Keep your watch clean
It may become difficult to pull out the crown due to
dirt and dust getting caught between the crown and
the watch case when the watch is worn for long
periods of time. To help prevent this from happening,
turn the crown freely back and forth occasionally
while it is in the normal set position. Wipe off any
water and moisture that adheres to the case, glass
and band with a soft, clean cloth. Any dirt left on the
case or band may cause skin rash.
A watchband will easily become soiled with dust and
perspiration because it is in direct contact with the
skin. Even a stainless or gold-plated band may begin
to corrode if it has not been cleaned for a long period
of time.
Mesh bands, because the meshes are very fine, will
lose their particular “flexibility” if they are left soiled
for a long time.
Metal watch bands should be washed periodically to
keep them looking beautiful at all times.
Metal watchbands are usually washed with a brush
in mild, soapy water and well wiped with a soft,
absorbent cloth to make sure all water is removed.
Pay attention to prevent any water from getting
inside your watch when the band is washed.
8. Periodic inspection
Getting your watch checked once in two or three
years is recommended to ensure long use and
trouble-free operation.
