Start using the watch!
• To adjust the time and calendar, see page 14.
7 How to charge the battery
This watch has a battery which is charged by exposing the dial to light such as direct sunlight or fluorescent lamps.
To obtain the best performance:
• Expose the dial to direct sunlight for several hours at least once a month.
• After taking off the watch, put it where 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, fully charge the battery.
Caution
• When the watch is covered with long sleeves, for example, the battery may not be charged sufficiently. Try to keep the watch exposed to light even when wearing the watch.
• Do not charge the battery at a high temperature (about 50˚C/122˚F or higher) such as on the dashboard.
See page 32 for charging time.

Precautions
• Water-resistance for daily use (up to 3 atmospheres):
This type of watch is resistant to minor exposure to water. 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 (up to 5 atmospheres):
This type of watch is resistant 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 (up to 10/20 atmospheres):
This type of watch may be used for skin diving; however, it is not designed to be used for scuba or saturated diving using helium gas.
• Be sure to use the watch with the crown pressed in fully (normal position) 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 cause malfunction.
• If seawater penetrates the watch, place the watch in a box or plastic bag and immediately take it in for repair. Otherwise, the pressure inside the watch will increase, and parts (glass, crown, buttons, etc.) may come off.
• If the watch is used in seawater, rinse with fresh water afterward and wipe with a dry cloth.
Keep your watch clean
• Keep your watch clean to prevent rust or dirt building up on the watch. They may stain your clothes.
• Wipe off dirt on the leather band with a soft and dry cloth to prevent it from discoloring.

Precautions
WARNINGS
Handling the secondary battery
• Do not remove the battery. When it is required, keep the battery out of the reach of children to prevent them from swallowing it.
• If the battery is swallowed, consult a doctor and seek medical treatment.
CAUTIONS
Cautions about charging
• Excessively high temperature at charging battery may cause discoloration and deformation of the exterior, and malfunction of the movement.
• Do not charge the battery at a high temperature (about 50˚C/122˚F or higher).
Examples:
– charging the battery by light such as an incandescent lamp or halogen lamp
– charging the battery where the temperature becomes extremely high—such as on the dashboard
To avoid injury
• DO NOT wear the watch where the temperature becomes extremely high—such as in a sauna. Otherwise the watch may become hot and cause skin burn.
To avoid malfunction
• DO NOT use the watch where the temperature is lower or higher than the operation temperature specified in the instruction manual. Doing so may cause the watch to malfunction or stop.
• DO NOT place the watch nearby any materials generating a strong magnetic field 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
They may interfere with the movement of the stepping motors in the watch and timekeeping becomes inaccurate.
Continued on the next page

50
Precautions
• 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.
• DO NOT apply any strong shock, for example, by dropping it onto a hard floor.
• 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 into contact with the watch, discoloration, melting, cracking, etc. may occur.
The case, band, or other parts may become discolored if the watch comes into contact with mercury, such as that used in thermometers.
Maintenance
Daily maintenance
• Rotate the crown while it is pressed in (position ) and press the buttons periodically so that they will not be rusty.
• Wipe off dirt, perspiration, and water from the case and glass with a soft cloth.
• To clean a metal, plastic, or rubber watchband, wash away dirt with water. Use a soft 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 finish.
Periodical inspections
Your watch needs an inspection once every two or three years for safety and longer usage. 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 genuine Citizen parts upon replacement.

How to use the rotating bezel
The rotating bezel is equipped on some models.
Using the bezel, you can easily calculate the followings:
1. Speed, driving distance, and required time
2. Fuel consumption rate, fuel consumption, and driving time
3. Conversion (weight/volume/distance)
• Rotate the outside scale for the calculation.
Outside scale
Inside scale
56
• The way of rotating the bezel differs depending on the type of the watch.
• You need to add a decimal point depending on calculation results.
1. Calculating speed, driving distance, and required time
Speed
(Speed index) always indicates a speed.
Driving distance

Driving distance
Required time

Speed index
In the circle A, the speed index points to “80.” Then any other part indicates a pair of driving distance and required time with the speed of 80 km/h. When the driving distance is 400 km (“40”), for example, the required time is 5 hours (“5:00”).
In the circle B, a driving distance and a required time are set. Then indicates the speed.

Driving time Speed index
In the circle A, the speed index points to “80.” Then any other part indicates a pair of fuel consumption and the maximum driving time with the fuel consumption rate of
80 l/h. When the fuel consumption is 400 l (“40”), for example, the maximum driving time is 5 hours (“5:00”).
In the circle B, fuel consumption and driving time are set. Then indicates the fuel
58 consumption rate.
3. Conversion

OIL LBS. : oil pounds distance
KM. : kilometer
STAT. : mile

Unit indexes
Set one of the indexes ( / ) to the figure you want to convert. Then the other indexes ( / ) point to converted figures.
The example shows 13.1 fuel pounds (base point) is equal to 16.4 oil pounds, 1.82 imperial gallon, 2.18 US gallon, and 8.25 liters.
