ank you for the purchase of this CITIZEN watch.
is watch has a rechargeable cell which is charged by exposing the watch dial to light such as direct
sunlight or uorescent lamps.
Notes on charging your watch
• Expose the watch dial towards direct sunlight for several hours at least once a month.
• Aer taking o the watch, put it in a position so that the dial is exposed to bright light, such as by a
window.
• Before storing the watch in a dark place for an extended period of time, be sure to charge it fully.

• If your watch has a screw-type crown, li up the crown to loosen it before operation. Be sure to press
the crown down rmly aer operation.
Adjusting the time
1 Pull the crown out to the second click position (time setting position, 2).
2 Rotate the crown to adjust the time.
3 Aer adjusting the time, rmly push the crown back into its normal position ( 0).
Adjusting the calendar
Do not adjust the calendar between 9:00 pm and 1:00 am. Otherwise the calendar may not change
correctly.
1 Pull the crown out to the rst click position (time setting position, 1).

Warnings on water-resistance performance
• Non-water resistant models are not designed to come into contact with any moisture. Take care not to
expose a watch with this rating to any type of moisture.
• Water-resistance for daily use: this type of watch is resistance to minor exposure to watch such as
accidental splashing. For example, you may wear the watch while washing your face, however it is not
designed to be used underwater.
• Upgraded water-resistance for daily use (tested to 5 bar) : is type of watch is resistance to moderate
exposure to water. You may wear the watch while swimming, however, it is not designed to be used
for skin diving.
• Upgraded water-resistance for daily use (tested to 10 or 20 bar): is type of watch may be used for
skin diving; however, it is not designed to be used for scuba or saturation diving.
• Before use, conrm the water-resistance level of your watch indicated on the dial and case, referencing
the table below. (e unit “bar” is roughly equal to 1 atmosphere.)
• “WATER RESIST(ANT) xx bar” may also be indicated as “W.R. xx bar.”

• Be sure to use the watch with the crown pressed in fully (normal position, 0 ) to ensure the water
resistance. If the crown of your watch is the screw down crown, be sure to tighten it completely.
• Do not operate the crown or buttons when the watch is wet.
• If water has penetrated the watch, or if the inside of the glass is fogged up and does not become clear
in a day, take the watch to your dealer or Citizen Service Center for repair. Leaving the watch in such
a state will rust the internal parts and malfunction.
• If sea water enters the watch, place the watch will increase and parts (such as the glass and buttons)
may come o.
• If the watch is used in seawater, rinse with fresh water aerward and wipe the a dry cloth aer each
use.
• e durability of a leather band may be aected when wet, owing to the properties of the material. In
the case of a watch of upgraded water resistance for daily use that is frequently used in water, fading,
peeling of adhesive or other problems may occur. It is therefore recommended to use another type of
band (metal or rubber watchband).

• Excessively high temperature when charging the watch may cause
discoloration and deformation of the components, and result in malfunction
of the movement.
• Do not remove the rechargeable cell. If it is removed, keep the rechargeable
cell out of reach of children to prevent ingestion.
• If the rechargeable cell is swallowed, consult a doctor and seek medical
treatment.
• Do not charge the watch at a high temperature (about 60oC/140oF or higher).
Examples:
- charging the watch too close to light such as an incandescent lamp or halogen lamp
(Halogen lights are not recommended for charging due to their high heat output.)
- charging the watch in locations where the temperature may become extremely high–such as on the
dashboard of a vehicle
• e watch will not operate if incorrect battery types are inserted.
• Never use a regular silver battery. e battery could overcharge during the charging process and burst,
causing damage to the watch or injuries to the wearer.

Temperature
• DO NOT use the watch where the temperature is lower or higher than the operation temperature
specied in the instruction manual. Doing so may cause the watch to malfunction or stop.
Magnetism
• DO NOT place the watch nearby any materials generating a strong magnetic eld such as:
- magnetic health equipment such as a magnetic necklace.
- a magnetic latch of a refrigerator door.
- a magnetic clasp on a handbag.
- speakers of a mobile phone.
- electromagnetic cooking devices.
• ey may interfere with the movement of the stepping motors in the watch and timekeeping becomes
inaccurate.
Static electricity
• DO NOT place the watch nearby household appliances generating static electricity.
• Timekeeping may become inaccurate if the watch is exposed to such strong static electricity as that
which is emitted from a TV screen.
Static
• DO NOT apply any strong shock, for example, by dropping it onto a hard oor.
Chemicals
• Avoid using the watch where it may be exposed to chemicals or corrosive gases. If solvents, such
as thinners or benzine, or substances containing such solvents come in contact with the watch,
discoloration, melting, cracking, etc. may occur.
e case, band, or other parts may become discolored if the watch comes into contact with some
household chemicals such as mercury that may be found in thermometers.

Maintenance
• Wipe o dirt, perspiration, and water from the case and glass with a so cloth.
• To clean metal, plastic, or rubber watchband, was away dirt with water. Use a so brush to remove
dust and dirt stuck in the gaps in a metal band.
• Do not use solvents (thinner, benzine, etc.), as they may damage the nish.
• Do not use a polishing type of cloth as this may damage the surface and certain treatments.
• Rotate the crown while it is pressed in full ( 0 ) and press the button periodically so they do not
become stuck due to accumulation of foreign matter.
Periodical inspection
• Your watch will need an inspection once every two or three years for safety and longer usage.
• To keep your watch water-resistant, the gaskets and other components need to be replaced regularly.
• Other parts need to be inspected if necessary. Always ask for genuine Citizen parts upon replacement.
