1. Features

This watch is a solar-powered watch that contains a solar cell in its face that drives the watch by converting light energy into electrical energy. It is equipped with numerous functions including a full-auto calendar that changes the date automatically (day, month and year change automatically through Febr uary 28, 2100 including leap years), a daily alarm function that can be set based on a 24-hour clock, and a chronograph function that allows measurement of time in 1/20 second units up to 59 minutes, 59.95 seconds.

2. Before Using

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 9 months without additional charging (when the power save feature is operating).

VPower Save Feature

When power generation stops as a result of light not shining on the solar cell during the time display or local time display, the second hand stops at the 12:00 position and only the hour and minute hands move to save power. When light once again begins to shine on the solar cell, the second hand advances rapidly to the current seconds and returns to moving at one second intervals.

<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.

<Insufficient Charging Warning Feature>

Regardless of the display of the watch at the time, when the watch becomes insufficiently charged, the watch changes to the time display and the second hand moves to the CHARGE position to inform the wearer that it is insufficiently charged. After the second hand moves to the CHARGE position, the watch changes to the time display in the order of the 24 hour hand, hour hand, minute hand and date wheel (function hand). Although the watch continues to keep time accurately at this time, the watch stops after about 5 days have elapsed

(roughly 2 days in the case the hands have been moved to switch the time when the insufficient charging warning feature is activated). When this happens, charge the watch by exposing to light so that it returns to one-second interval movement. However, since the time is incorrect when the watch is exposed to light and changes to the insufficient charging warning display after it has stopped due to insufficient charging, set the time after

A sufficiently charging the watch.

Notes:

• Chronograph measurement stops and the chronograph is reset even when measurement is in progress.

• The set time (time difference) is retained for the local time.

• The alarm will not sound even if it is set.

• Crown (mode switching) and button operations will not function.

<Time Setting Warning Feature>

When the watch is recharged by exposing to light after it has stopped, the second hand moves to the SET position to inform the wearer that the time is incorrect. Although the 24 hour hand, hour hand and minute hand will begin to move after the second hand moves to the SET position, since the time is incorrect, reset the time and date after sufficiently charging the watch.

Notes:

• Crown and button operations will not function except for time and calendar setting operations.

• When the crown is pulled out to position 2 (time correction position) in the time or date setting mode, the time setting warning feature is canceled.

The second hand will remain stopped at the SET position unless the crown is pulled out to position 2 and the time is

7 set.

• In the case the watch has stopped due to insufficient charging, a minimum of 30 minutes are required until the watch changes to the time setting warning display even if sufficiently exposed to light.

<Overcharging Prevention Feature>

The overcharging prevention feature is activated when the secondary battery is fully charged so that it is not charged further.

15

<Power Save Feature>

16

When power is no longer generated as a result of light not shining on the solar cell when the watch is in the time/calendar mode or local time mode, the second hand moves to the 0 seconds position and stops to save power by reducing current consumption.

The 24 hour hand, hour hand and minute hand continue to keep the correct time even though the second hand is stopped. Furthermore, the calendar is corrected in coordination with the 24 hour hand, hour hand and minute hand.

A second hand stops at the 0 seconds position, the second hand is rapidly advanced to the current seconds and begins one-second interval movement. However, when the insufficient charging warning feature has been activated, the second hand moves to the CHARGE position and stops, and when the time setting warning feature has been activated, it moves to the SET position and stops. When the watch has stopped, the second hand moves to the STOP position and remains stopped.

Note:

• During the time the secondary battery is fully charged and the overcharging prevention feature is operating, the power save feature does not operate even when power generation is interrupted as a result of not exposing the solar cell to light.

Similarly, the power save feature will also not operate when the secondary battery has temporarily become fully charged as a result of exposure to intense light.

6. Notes Regarding Handling of this Watch

<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 it being concealed and unable to be exposed to light.

• When you take the watch off, try to place it in as bright a location as possible to ensure that it always keeps the correct time.

CAUTION

Charging Precautions

• Avoid recharging at high temperatures (over about 60°C /140°F) since this may result in damage to the watch during recharging.

Examples: Charging the watch in close proximity to an incandescent lamp, halogen lamp or other light source that can easily reach high temperatures, charging the watch in a location that reaches high temperatures such as on a car dashboard.

• When charging the watch with an incandescent lamp, always make sure the watch is at least 50 cm (20 in.) away from the lamp so that it does not reach excessively high temperatures during charging.

[Explanation of Hands During Chronograph Measurement]

When the crown is turned and the mode hand is set to the chronograph [CHR] mode, the second hand and function hand are rapidly advanced to the 0 position and the watch enters the chronograph mode.

• Second hand:

Switches to the chronograph second hand. The second hand advances rapidly and makes one revolution only when starting at 0 seconds, after which it moves in 1 second increments to measure chronograph seconds.

• Function hand:

Switches to either chronograph minutes or chronograph 1/20th seconds. The function hand moves in one minute increments to measure chronograph minutes. When button (B) is pressed when the chronograph is stopped, the function hand switches to 1/20th seconds display during time button (B) is pressed.

Note: 24 hour hand, hour hand, minute hand, date wheel:

• Continue to display the current time when the watch has been switched from the time/calendar mode.

• Continues to display local time when the watch has been switched from the local time mode.

• Continues to display the alarm set time when the watch has been switched from the alarm mode.

12. Setting Local Time

The local time function allows the time in a different time zone to be set separately from the current time. Local time is set by performing a time difference correction in 1 hour units based on the current time (time of the time mode/TME). The minute and second hands move in coordination with the current time.

Local time setting position

(2)

1. Turn the crown to set the mode hand to the local time [L-TM] mode.

2. Pull out the crown to Position 2 (local time setting position).

3. Click the crown to the right or left to correct the time difference.

• When the crown is clicked to the right, the hour hand moves by 1 hour in the clockwise direction.

• When the crown is clicked to the left, the hour hand moves by 1 hour in the counterclockwise direction.

37

38

Note: The hour hand is not advanced rapidly even if the crown is continuously clicked two or more times. Perform correction accurately 1 hour at a time. Furthermore, the range of time difference correction is ±23 hours based on the current time.

4. Always make sure to return the crown to the normal position after correcting the time difference.

Note: If the hour hand passes 12:00 AM (midnight) during correction, the date is advanced by 1 day following completion of hand movement. If the time difference is corrected in the counter-clockwise direction and the hour hand passes back over 12:00 AM, although the date is corrected following completion of hand movement, since the date is corrected by 30 days in the clockwise direction, it takes about 2-3 minutes for the date to be corrected. Pay attention to AM and PM when correcting time difference.

Note: When returning the time difference to the original setting, return the hour hand in the direction opposite that when the time difference was corrected.

13. Using the Alarm

The alarm function uses a 24-hour clock. Once the alarm has been set, the alarm sounds for 15 seconds when the set time is reached once a day. The time at which the alarm sounds applies to the time (TME) mode, and cannot be set based on the local time (L-TM).

• Turning the crown rapidly (continuously clicking two or more times) causes the hands to advance rapidly. When stopping the hands, click the crown once to the right or left. When the hands are not stopped manually, they stop automatically after being corrected by 12 hours.

• Set the alarm while making sure to not to mistake AM and PM by referring to the 24 hour hand.

4. Return the crown to the normal position after setting the alarm time.

[Switching Alarm ON and OFF]

The alarm is switched ON and OFF each time button (A) is pressed when the crown is pulled out to Position 1 or Position 2 in the alarm mode.

0-Position Correction

When performing the all-reset procedure, first make sure that the watch is fully charged and the second hand is moving in one second increments. If the all-reset procedure is performed when the watch is insufficiently charged, it may not function properly or remain stopped following the all-reset procedure.

1. Turn the crown to set the mode hand to the chronograph [CHR] mode.

2. Pull out the crown to Position 2 (0-position correction mode).

• Each of the hands and date wheel move to their respective 0 positions stored in memory and then stop.

3. Press buttons (A) and (B) simultaneously and then release.

• Following a confirmation tone, each of the hands perform a demonstration movement in the order of the function hand, 24 hour hand, hour hand, minute hand and second hand to indicate that the all-reset procedure is finished.

Note: Following the all-reset procedure, make sure to properly reset each mode after performing 0-position correction for each hand before using the watch. The watch will remain stopped and not run unless 0-position correction is performed.

• 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

• 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.

CAUTION:

Keep your watch clean.

• 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.

47

48

• 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.

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.

• 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.
