A. BEFORE USING
This watch is an analog solar-powered watch having a transparent solar cell
located beneath the crystal that converts light energy into electrical energy to
power the watch.
Before using, expose the watch (solar cell) to light to make sure it is
sufficiently charged.
Since it takes time to recharge the watch until it starts running again
once it has stopped, try to make sure the watch is charged everyday.
If the watch has stopped running, expose it to intense light such as
sunlight to recharge. When recharging using light of low illuminance of
3,000 lx or less, pull out the crown before charging. After charging,
always make sure to correctly set the time and return the crown to the
normal position before using the watch.
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 4.5 months without further charging.
To use this watch comfortably, make sure that the watch is always recharged
before it stops.
There is no risk of overcharging this watch. (Overcharge Prevention Function is
included)
B. SETTING THE TIME
For models in which the crown is provided with a cover, open the crown cover to
set the time. Once the time has been set, securely close the crown cover.
WWSetting the time
1. Pull the crown out to the time setting position (the second hand will stop when
the crown is pulled out).
2. Turn the crown to set the time.
3. After setting the time, firmly push the crown back in to the normal position.

WWTime Setting Warning Function
Although the watch hands will begin to move
when the watch is charged after stopping,
since the time is incorrect, the second hand will
move by irregular two second interval
movement to indicate that the time is incorrect.
When this happens, fully recharge the watch
and reset the time. The watch will continue to
run by irregular two second interval movement
until the time is reset even if fully charged.
WWOvercharge 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.
WWInsufficient Charge Warning
Function
The second hand moves by two second
interval movement to indicate insufficient
charging. Although the watch keeps the
correct time when this happens, the watch will
stop after about 1 week after the start of two
second interval movement.
Recharge the watch by exposing to light. The
watch will then begin to run normally again.

D. CARE AND HANDLING DURING CHARGING
WWNotes on use
Take care to charge your watch during use.
Please note that if you wear long sleeves, the watch can easily become
insufficiently charged because it is hidden and not exposed to light.
• When you take the watch off, place it in as bright a place as possible, and it
will always continue to run properly.
WWNotes on recharging
• Avoid recharging at high temperatures (over about 60°C/140°F), otherwise the
watch will be damaged during recharging.
(eg) Charging the watch near a light source that easily becomes hot, such as
an incandescent lamp or a halogen lamp.
Charging in a place that easily becomes hot, such as a dashboard.
When you charge the watch by an incandescent lamp, take a distance about
50cm (20in.) from the light source to prevent extremely high temperature.
E. REPLACING THE SECONDARY BATTERY
Unlike ordinary batteries, the secondary battery used in this watch doesn't
have to be periodically replaced due to repeated charging and discharging.
CAUTION
Never use another battery different from the secondary battery used in this
watch.
The watch structure is so designed that a different kind of battery other than that
specified cannot be used to operate it. In case a different kind of battery such as
a silver battery is used by some chance, there is a danger that it will be
overcharged to burst, causing damage to the watch and even to the human
body.

When recharging using light of low illuminance of 3,000 lx or less, pull out the
crown before charging. Figures in parentheses in the table indicate charging
times with the crown pulled out.
* The recharging time is the time when the watch is continuously exposed to
light.
Full charge time.......... The time to fully recharge after the watch has stopped.
One day usage........... The time required for the watch to run for one day with
one second interval movement

G. PRECAUTIONS

Operation of the crown
with moisture visible

•If seawater enters the watch, place the watch in a box or plastic bag and
immediately take it in for repair. Otherwise, pressure inside the watch will
increase, and parts (crystal, crown, buttons, etc.) may come off.
CAUTION: Keep your watch clean.
•Leaving dust and dirt deposited between the case and crown may result in
difficulty in pulling the crown out. Rotate the crown while in its normal
position, from time to time, to loosen dust and dirt and then brush it off.
•Dust and dirt tend to be deposited in gaps in the back of the case or band.
Deposited dust and dirt may cause corrosion and soil your clothing. Clean the
watch occasionally.
Cleaning the Watch
•Use a soft cloth to wipe off dirt, perspiration and water from the case and
crystal .
•Use a soft, dry cloth to wipe off perspiration and dirt from the leather band.
•To clean a metal, plastic, or rubber watchband, wash away dirt with mild soap
and water. Use a soft brush to remove dust and dirt jammed in the gaps in
the metal band. If your watch is not water-resistant, take it to your dealer.
NOTE: Avoid using solvents (thinner, benzine, etc.), as they may mar the finish.
15
•Water-resistance for daily use (to 3 atmospheres): This type of watch is
water-resistant to minor exposure to water. For example, you may wear the
watch while washing your face; however, it is not designed for use
underwater.
•Upgraded water-resistance for daily use (to 5 atmospheres): This type of
watch is water-resistant to moderate exposure to water. You may wear the
watch while swimming; however, it is not designed for use while skin diving.
•Upgraded water-resistance for daily use (to 10/20 atmospheres): This type of
watch may be used for skin diving; however, it is not designed for scuba or
saturated diving using helium gas.
CAUTION
•Be sure to use the watch with the crown pressed in (normal position). If your
watch has a screw-type crown, be sure to tighten the crown completely.
•Do NOT operate the crown with wet fingers or when the watch is wet. Water
may enter the watch and compromise water-resistance.
•If the watch is used in seawater, rinse with fresh water afterward and wipe
with a dry cloth.
•If moisture has entered the watch, or if the inside of the crystal is fogged up
and does not become clear within a day, immediately take the watch to your
dealer or Citizen Service Center for repair. Leaving the watch in such a state
will allow corrosion to form inside.
14

•Do NOT subject the watch to a strong shock such as dropping it onto a hard
floor.
•Avoid using the watch in an environment where it may be exposed to
chemicals or corrosive gases.
If solvents, such as thinner and benzine, or substances containing such
solvents come in contact with the watch, discoloration, melting, cracking, etc.
may result. If the watch comes in contact with mercury used in thermometers,
the case, band or other parts may become discolored.
Periodical inspections
Your watch needs inspection once in every two or three years for safety and
long use.
To keep your watch water-resistant, the packing needs to be replaced regularly.
Other parts need to be inspected and replaced if necessary.
Ask for Citizen geuine parts upon replacement.
17
CAUTION: Operating environment
•Use the watch within the operating-temperature range specified in the
instruction manual.
Using the watch where temperatures are outside the specified range, may
result in deterioration of functions or even stoppage of the watch.
•Do NOT use the watch in places where it is exposed to high temperature,
such as in a sauna.
Doing so may result in a skin burn.
•Do NOT Ieave the watch in a place where it is exposed to high temperature,
such as the glove compartment or dash-board of a car.
Doing so may result in deterioration of the watch, such as deformation of
plastic parts.
•Do NOT place the watch close to a magnet.
Timekeeping will become inaccurate if you place the watch close to magnetic
health equipment such as a magnetic necklace or a magnetic latch of a
refrigerator door or handbag clasp or the earphone of a mobile phone. If this
has occurred, move the watch away from the magnet and reset the time.
•Do NOT place the watch close to household appliances that generate static
electricity.
Timekeeping may become inaccurate if the watch is exposed to strong static
electricity, such as is emitted from a TV screen.
