2. Before Using
3. Displays and Buttons
This watch is a solar-powered watch. Please fully charge the watch before
using by exposing it to light.
A secondary battery is used in this watch to store electrical energy. This
secondary battery is a clean energy battery that does not contain mercury or
other toxic substances. Once fully charged, the watch will continue to run for
about five months without additional charging.
<Proper Use of this Watch>
To use this watch comfortably, make sure to recharge it before it stops running
completely. Since there is no risk of overcharging (Overcharging Prevention
Feature), it is recommended that the watch be recharged everyday.

4. Functions Unique to Solar-Powered
Watches
[Normal Time Display]
When the watch becomes
insufficiently charged, the
following warning features
will be activated to inform
the wearer that the watch
is insufficiently charged.

If charged
The watch hands resume 2-second interval movement when the watch is charged by
exposing to light. However, the time is incorrect as a result of the watch having stopped
due to being insufficiently charged. Sufficiently charge the watch until it resumes 1second interval movement and reset the time before use.

7
[Insufficient Charging Warning Feature]
When the capacity of the secondary battery decreases as a result of light not
shining on the solar cell, the second hand switches from 1-second interval
movement to 2-second interval movement (insufficient charging warning
feature). Although the watch continues to keep time accurately at this time, the
watch stops after about 5 days have elapsed after the second hand has
switched to 2-second interval movement. When this happens, charge the
watch by exposing it to light until the second hand returns to 1-second interval
movement.
Notes: • During chronograph
measurement, measurement
stops and the chronograph
second hand is reset to the 0
seconds position.
• The chronograph minute hand
stops at any arbitrary position.
Return it to the 0 minutes position
by pressing button (B).
[Quick Start Feature]
If the watch has stopped as a result of being insufficiently charged, the second
hand will begin 2-second interval movement and the watch will begin to run
about 10 seconds after the watch is exposed to light (approx. 500 lx). (The
time until the hands begin to move varies depending on the model.) Please
note, however, that the watch will stop again if the watch is blocked from the
light and is not sufficiently charged.

[When the Watch has Stopped due to Insufficient Charging]
When the capacity of the secondary battery decreases as a result of the solar
cell not being exposed to light, the watch will stop due to being insufficiently
charged. The Quick Start Feature will be activated and the hands will begin to
move if the solar cell is exposed to light. Sufficiently charge the watch by
exposing to light so that it returns to the normal time display (1-second interval
movement).
Note: • The time is incorrect when the watch has stopped as a result of being
insufficiently charged even if the watch starts to run. Reset the watch
to the correct time before using.
5. General Reference for Charging Times
Recharging time varies according to the watch model (such as the color of the dial). The
times in the table below should therefore only be used as a rough reference.
* Charging time refers to the amount of time during which the watch is continuously
exposed to light.

6. Handling Precautions
<Try to Keep the Watch Charged at All Times>
Please note that if you wear long sleeves, the watch can easily become
insufficiently charged as a result of the watch being covered and not being
exposed to light. The watch will continue to run properly if it is placed in as
bright a location as possible even when not being worn.
Charging Precautions
• Allowing the watch to reach high temperatures during recharging can
damage the watch. Avoid recharging in locations that can reach high
temperatures (about 60°C /140°F or higher).
Examples: • Charging by placing the watch in close proximity to a light source
that easily becomes hot such as an incandescent lamp or
halogen lamp.
• Charging the watch in a location that can easily become hot
such as on an automobile dashboard
12
• When charging using the light from an incandescent lamp, charge while
being careful that the watch does not become excessively hot by placing at a
distance of at least 50 cm (20in) from the lamp.
Handling of Secondary Battery
• Please do not attempt to remove the secondary battery from the watch.
• If the secondary battery has been unavoidably removed, store it in a location
out of the reach of small children to prevent accidental swallowing.
• If the secondary battery should happen to be swallowed, please consult a
physician and seek medical attention immediately.
Only Use the Specified Secondary Battery
• Never use a secondary battery other than the secondary battery used in this
watch. Although the watch is designed not to operate if another type of
secondary battery is installed, since this may result in overcharging that can
cause the secondary battery to rupture, there is the risk of both damage to
the watch and injury to the wearer.
• Only use the specified secondary battery when replacing the secondary
battery.

7. Replacing the Secondary Battery
8. Setting the Time and Date
Unlike ordinary silver-based batteries, the secondary battery used in this watch
does not have to be periodically replaced since it is able to be charged and
discharged repeatedly.
In the case the crown is of the screw-lock type, loosen the screw by turning the
crown to the left before operating the crown, and after having returned the
crown to the normal position following operation, turn it to the right while
pushing it in to securely retighten it.

10. Zero Positioning of Chronograph
Second Hand
When resetting the chronograph, if the chronograph second hand does not
return to the 0 seconds position or if the chronograph second had has shifted
out of position due to strong impact, perform zero positioning of the
chronograph second hand according to the procedure described below.
• In the case the crown is of the screw-lock type, loosen the screw before
operating the crown.
• The zero positioning procedure cannot be performed while the insufficient
charging warning feature is activated (while the second hand is moving at 2second interval movement due to the watch being insufficiently charged).
Sufficiently charge the watch and check that the second hand is moving at 1second interval movement before performing the zero positioning procedure.

• Water-resistance for daily use (to 3 atmospheres): This type of watch is waterresistant 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-lock type 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.
24
• 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.
25
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.
26
• 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.
