This watch includes a rechargeable cell. This cell is fed electricity by a
solar cell in which light energy is converted to electrical energy.
Product Features
The watch operates by converting sunlight into electrical energy, which is stored in a rechargeable
battery. e rechargeable battery is a clean energy source that does not contain mercury or other harmful
substances. When the watch is fully charged, it will operate continuously for approximately seven months.
A watch that has stopped due to an insuciently charged cell will start operating immediately
when exposed to light.
Special hand movement to let you know when the reserve energy is getting low.
is protects the rechargeable cell from overcharging. is provides worry free enjoyment,
not matter how much light your watch is subjected to.
This feature enables elapsed time measurement (stopwatch.) You can measure time in
activities such as walking, jogging, bicycle riding, etc.

is watch uses a built-in rechargeable cell to store electrical energy.
Charge the watch by exposing the dial to light such as direct sunlight or
uorescent lamps.
Recharging your watch
To ensure optimal operation, be sure to perform the following.
•Chargethewatchindirectsunlight(outdoors)onceamonthfor
5 to 6 hours.
•Whenyoutakeyourwatchoff,besuretoplaceitinalocation
where the dial can receive light. An ideal location might be a
window sill where it can receive direct sunlight.
Wearing clothes that cover the watch may inhibit sufficient light from reaching the
watch face, resulting in insucient charging.
Avoid charging the watch under high temperature conditions (approximately
60°C/140°F or more).

When the rechargeable cell charge reaches a low
power state, the Insufficient Charge Warning
Function engages. This cause the second hand
to move in two-second intervals (two-second
interval movement). Be sure to immediately fully
charge your timepiece by exposing it to light.

WARNING
Water-resistance
performance
There are several types•
of water-resistant
watches, as shown in the
following table. The unit
“bar” is roughly equal to
1 atmosphere.
For correct use within the•
design limits of the watch,
confirm the level of water-
resistance of your watch, as
indicated on the dial and
case, and consult the table.
Precautions

18
19
English
CAUTION
Be sure to use the watch with the crown pressed in (normal position). If your•
watch has a screw down crown, be sure to tighten the crown completely.
Do NOT operate the crown or button 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.
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.
WARNING Water-resistance performance
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.

20

English
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 leave 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.
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 damage the finish.

22
23
English
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 genuine parts upon replacement.
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.

24
25
English
CAUTION Charging precautions
Do not charge the watch in a high-temperature environment (about 60°C/140°F•
or more). Overheating while charging can cause the watch exterior to become
discolored, the watch to deform or the movement to be damaged.
Example) • Chargingclosetoincandescentlighting,halogenlamps,orother
lighting sources that easily become hot.
 • Chargingonsurfacesthatcaneasilybecomehot,suchasacar
dashboard.
When charging with incandescent lighting, halogen lamps, or other lighting•
sources that easily become hot, place the watch at least 50 cm (20 in.) away from
the source to avoid overheating.
WARNING Handling the rechargeable cell
Do not remove the rechargeable cell from the watch yourself. If you must remove•
the cell, store it out of reach of children to avoid accidental ingestion.
If the rechargeable cell is ingested, consult a doctor immediately.•
Do not throw away with regular trash. Please follow your local government•
disposal regulations to prevent the risk of fire or environmental contaminations.
WARNING Do not use anything other than the specified
rechargeable cell
The watch will not operate if incorrect battery types are inserted.•
Never use a regular silver battery. The battery could overcharge during the•
charging process and burst, causing damage to the watch or injuries to the wearer.
