A. BEFORE USING

This watch is powered not by an ordinary battery, but by converting photo energy to electrical energy.

Before using, expose to light and make sure the watch is sufficiently charged.

See "G. TIME REQUIRED FOR CHARGING" for charging time reference.

A rechargeable cell is used in this watch to store electrical energy.

This rechargeable cell is a clean energy battery which doesn't use any toxic substances such as mercury. Once fully charged, the watch will continue to run for about 6 months without further charging.

To use this watch comfortably,

make sure that the watch is always recharged before it stops.

There is no concern for overcharging this watch. (Overcharge Prevention

Function is included)

We recommend that you recharge the watch everyday.

Date and Hour hand correction position

Crown

Time (24hour, minute,second) correction position

Normal position

Second hand

Solar cell

24 hour hand

* If the crown is of the screw- type, set the time and calendar after first loosening the screw. Retighten the screw after the time and calendar have been set.

3

■ Setting the Time

(1) Pull the crown out to the time correction position. (The second hand stops when the crown is pulled out.)

(2) Turn the crown to set the

24 hour hand and minute hand to the current time. At this time, the movement of the hour hand is linked with the movement of the 24 hour hand.

(3)

Push the crown back in to the normal position. (The second hand begins to move when the crown is pushed in.)

(4) Pull the crown out to the date correction position. (1st click position)

(5) Turn the crown to the right (clockwise direction) and set the hour hand to the current time. Pay attention to AM and PM since the location of the hour hand where the date changes is approximately 12:00 midnight.

(6) Securely return the crown to the normal position.

Reading the Time Based on a 24-Hour Clock

Read the time on the inside (1:00 to 12:00) with the short hand of the 24 hour hand, and the time on the outside (13:00 to 24:00) with the long hand.

4

■ Setting the Date

(1) Pull the crown out to the date correction position.

(2) Turn the crown to the left (counter-clockwise direction) and set the date.

(3) Securely return the crown to the normal position.

* Since the date is linked to movement of the hour hand, the date changes when the hour hand approaches 12:00 midnight. Please note this operation when using as a dual time watch.

* Do not attempt to correct the calendar when the hour hand is between the hours of 9:00 PM and 1:00 AM. Setting the calendar during this time may result in the date not changing on the following day.

5

C. USING AS A DUAL TIME WATCH

This watch allows the hour hand only to be corrected independently without stopping the watch. It can be used as a dual time watch by setting the 24 hour hand and hour hand to different times. After correcting the time, the hour hand is used to indicate the "local time hours".

Hour (local time hour) hand

Minute hand

Local time correction position

Crown

Normal position

24 hour hand

6

■ Correcting the Local Time Hours

(1) Pull the crown out to the local time correction position. (1st click position)

(2) Turn the crown to the right (clockwise direction) and set the hour hand to the desired time. The hour hand can be corrected in +1 hour increments in the clockwise direction. Set the time while paying attention to AM and PM.

(3) Securely return the crown to the normal position.

* The hour hand cannot be corrected in the counter-clockwise direction. The date changes when the crown is turned to the left (counter-clockwise). In addition, since the calendar is linked with the operation of the hour hand, it may be necessary to correct the calendar after correcting the hour hand depending on the time to which the hour hand was set.

9

■ Insufficient Charge Warning Function

The second hand changes to a two second interval movement to indicate insufficient recharging.

Even in such a case, the watch keeps correct time, but about 3 days after the two second interval movement begins, the watch will stop.

After exposing the watch to light, recharging takes place and the watch returns to one second interval movement.

2sec.

2sec.

■ Quick Start Function

Two second interval movement

The watch will stop if it is completely discharged.

It will begin to operate soon after it is exposed to light.

(However, the time to start may vary according to the brightness of the light.)

10

■ Time Setting Warning Function

If the watch stops, subsequent exposure to light allows the Quick Start Function to start again, and

the second hand moves with a hitch to indicate that the time incorrect.

In this case, quickly recharge the watch and reset the time.

Otherwise, the hitch movement will continue.

2sec.

■ Overcharge Prevention Function

Hitch movement

There is no risk of overcharging.

Once the rechargeable cell is fully recharged, the overcharging prevention feature comes into operation and prevents overcharging.

11

E. CARE AND HANDLING DURING CHARGING

■ Notes 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.

■ Notes 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 with an incandescent lamp, halogen lamp or other light source that generates heat, take a distance about 50cm (20in.) from the light source to prevent extremely high temperature.

12

F. REPLACING THE RECHARGEABLE CELL

Unlike ordinary batteries, the rechargeable cell 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 rechargeable cell 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.

H. USING THE SLIDE RULE

Flying distance and other navigation calculations as well as general calculations can be performed using the slide rule located around the outside of the dial. This slide rule is not able to display decimal places for calculation results, and should only be used as a general reference as an alternative to more accurate calculations. Turning the crown at the

8:00 position allows the slide rule around the dial (Outside Scale) to be rotated.

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.

30

• 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.

31

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.

32

• 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.
