1. Features

This watch is a combination solar-powered watch that contains a solar cell in its face that drives the watch hands, alarm, chronograph, timer and numerous other functions by converting light energy into electrical energy.

It is also equipped with convenient functions including three power save modes that reduce power consumption when light is not shining on the solar cell, and a "charge indicator" that roughly indicates how much the secondary battery is charged.

2. Before Using

This watch is a solar-powered watch. Before using, allow light to shine onto the watch so that it is sufficiently charged.

If the manual power save function has been activated, cancel it before charging. (Refer to p.58 for information on the procedure for canceling the manual power save function.)

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 a maximum of 4 years without additional charging (when in the power save 2 mode).

[Proper Use of this Watch]

To use this watch comfortably, make sure to recharge it before it stops running completely. There is no risk of overcharging the watch no matter how often it is recharged (Overcharging Prevention Function).

It is recommended that the watch be recharged everyday.

4. Switching the Mode (Display Functions)

In addition to the time and date modes, this watch is also equipped with three additional modes consisting of the alarm, chronograph and timer modes. The mode can be switched by turning the crown. Check the current mode with the mode hand.

5. Checking 0-Position of Each Hand

Before using this watch, check that the 0-position (base position of each hand) is set correctly to ensure that the functions of the watch operate properly by performing the following procedure.

<0-Position Check>

1. Turn the crown while in the normal position to set the mode hand to the chronograph [CHR] mode.

2. Pull the crown out to the second click (0-position correction position).

3. The second hand, minute hand, hour hand, 24 hour hand, UTC hour hand and UTC minute hand rapidly advance to the 0-position (12:00 position).

Note:

• When each hand is not at the 0-position, perform the "0-position correction" procedure. If this 0-position is out of alignment, each hand will not indicate the correct position.

<0-Position Correction (Setting to the Watch Base Position)>

When setting the 0-position of each hand, always make sure to turn the crown forward (clockwise) to set each hand to its 0-position in the clockwise direction.

1. Turn the crown while in the normal position to set the mode hand to the chronograph [CHR] mode.

2. Pull the crown out to the second click (0-position correction position).

3. The second hand, minute hand, hour hand, 24 hour hand, UTC hour hand and UTC minute hand rapidly advance to the position stored in memory.

4. "HR" lights during digital display 2 indicating that the watch is in the correction state.

5. Turning the crown forward (clockwise) allows correction to be made in the positive direction. Turning the crown continuously allows the 0-position to be corrected continuously.

6. Pressing button (A) switches the correction location between "MIN" (minute hand) and "SEC" (second hand) each time it is pressed.

7. Turn the crown forward (clockwise) to align each hand at the 0-position at each correction location. Although correction can be made in the negative direction by turning the crown backward (counter-clockwise), always make sure to set the 0-position by turning the crown forward to ensure that the 0-position is set correctly.

8. The 24 hour hand is corrected in conjunction with the hour hand.

9. The UTC hour and minute hands are corrected in conjunction with the minute hand.

10. The second hand can only be corrected in the forward (clockwise) direction only.

11. After correcting, return the crown to the normal position.

12. After correcting the 0-position of each hand, reset the time, calendar and other modes before using the watch.

Note:

• None of the buttons on the watch operate during movement of each hand.
  Operate the buttons only after the hands have stopped moving.

6. Accessing Times or Dates of Major Cities

The time or date of major cities pre-registered in this watch can be easily accessed by pressing the buttons.

1. Turn the crown to set the mode hand to the time [TME] or [CAL] calendar mode.
2. When button (A) is pressed, the times or dates of major cities are displayed while scrolling up each time it is pressed.
3. When button (B) is pressed, the times or dates of major cities are displayed while scrolling down each time it is pressed.

5. All segments of the digital display are shown when either of the buttons is released.

6. This fully lit display is canceled when the crown is returned to the normal position.

7. After canceling, a confirmation tone is sounded after which each of the hands perform a demonstration movement in the order of the second hand, minute hand, UTC minute hand, UTC hour hand and 24 hour hand to indicate that the all-reset procedure is finished.

8. After the demonstration movement, pull the crown out to the second click to switch the watch to the watch base position setting state.

Always make sure to set the 0 position (base position) for the hour hand, minute hand, second hand, 24-hour hand and UTC hour and minute hands while referring to "5. Checking 0-Position of Each Hand <0 -Position Correction>".

Note:

• After setting the 0 position (base position) for each hand, correctly reset the time, calendar and other modes before using the watch.

15. Functions Unique to Solar-Powered Watches

[Insufficient Charging Warning Function] (Analog Display)

Regardless of the display (mode) of the watch at the time, when the watch becomes insufficiently charged, the watch changes to the time display and the second hand begins to move at two-second interval movement. Although the 24 hour hand, hour hand and minute hand continue to keep the correct time, the watch stops after about 1.5 days have elapsed after the insufficient charging warning function is activated. When this happens, charge the watch by exposing to light so that it returns to one-second interval movement. However, if the watch again becomes insufficiently charged without setting the time after it has been sufficiently charged by exposing to light as a result of having stopped due to being insufficiently charged, it will not return to the normal display unless the time is set after again sufficiently charging.

Two second interval movement

(Digital Display)

"CHARGE" flashes on digital display area 2 in all modes.

• The watch displays the normal time display regardless of the position of the crown (pulled out to the first or second click) in each mode except for the calendar mode.
• When the watch is in the calendar mode, the normal date display is displayed regardless of the position of the crown.

Notes:

• Crown operations do not function (except for mode switching (with the crown in the normal position)) in any of the modes.
• Button operations do not function, except for changing the city name (UP/DOWN), in any of the modes.
• The alarm tone does not sound even if it is set.
• The chronograph is interrupted and reset even if measurement is in progress.

• Timing by the timer is immediately interrupted even if timing is in progress.

• In the case the watch switches to the insufficient charging warning function as a result of being insufficiently charged, it takes a minimum of 30 minutes for the watch to return to the normal operating state even if sufficiently exposed to light.

When the insufficient charging warning function is canceled as a result of exposing the watch to light and sufficiently charging, the watch returns to the mode indicated by the mode hand.

[Time Setting Warning Function]

(Analog Display)

The watch stops when insufficient charging continues for about 1.5 days. When the watch is charged by exposing to light after having stopped due to insufficient charging, each hand is rapidly advanced to the base position and stops. Each hand remains stopped until the time is reset.

(Digital Display)

The initial setting display (12 hours, 00 minutes, 00 seconds, UTC or January 1 SA) flashes in the time or calendar mode.

1. Set the mode hand to the time mode and pull the crown out to the second click to set the time. Flashing of the digital display is only canceled in the time mode. After correcting the time, return the crown to the normal position.
2. Set the mode hand to the calendar mode and pull the crown out to the second click to set the date. Flashing of the digital display is canceled in the calendar mode.
3. After correcting the date, return the crown to the normal position.

Note:

• The time setting warning function will not be canceled unless the time is first set followed by setting the date.
• It takes a minimum of 30 minutes until the watch switches to the time setting warning display after the watch has stopped due to insufficient charging even if the watch is exposed to light.

[Overcharging Prevention Function]

The overcharging prevention function is activated when the secondary battery is fully charged so that it is not charged further. This allows the user to charge the watch without any risk of overcharging.

[Power Save 1]

When power is not generated as a result of the solar cell not being exposed to light, the second hand stops when it reaches the zero seconds position and the watch automatically enters the power save state to inhibit power consumption of the secondary battery.

(Analog Display)

• The second hand stops at the base position (12:00).
• Other hands continue to keep the correct time.

(Digital Display)

• In coordination with the analog second hand stopping at the zero seconds position, the entire digital display goes out. However, the alarm, chronograph and other functions continue to measure time internally even though there is no display.

Power Save 1 is canceled when power generation resumes as a result of exposing the solar cell to light.

• The second hand rapidly advances to the current time and begins one-second interval movement.
• The digital display reappears simultaneous to resumption of power generation.

Notes:

• During the time the secondary battery is fully charged and the overcharging prevention function is activated, the power save function is not activated even if power generation is interrupted as a result of the solar cell not being exposed to light. In addition, the power save function is similarly not activated when the solar cell is exposed to intense light and temporarily becomes fully charged.

[Power Save 2]

When the watch reaches the first 12:00 AM position (when the 24 hour hand, hour hand, minute hand and UTC minute hand all reach the reference position) after the Power Save 1 state has continued for 3 days, it enters the Power Save 2 state.

(Analog Display)

• The 24 hour hand, hour hand, minute hand, second hand and UTC minute hand stop at the reference position (12:00).
• The UTC hour hand stops moving immediately.

(Digital Display)

• The digital display remains completely out in continuation from the Power Save 1 state.

Notes:

• Crown and button operations do not function in any mode.
• The alarm tone does not sound even if it is set.
• The tone indicating that time is up does not sound in the timer mode.

Similar to Power Save 1, Power Save 2 is canceled when power generation resumes as a result of exposing the solar cell to light.

Each hand rapidly advances to the current time and begins to move.
- The digital display reappears simultaneous to resumption of power generation. However, the chronograph returns to the reset state and the timer switches to the initial setting display.

[Manual Power Save]

When not using the watch for an extended period of time, activating the manual power save function after first charging the watch until all three bars of the graphic display of the secondary battery charge indicator are lit enables the watch to be stored for a longer period of time.

Furthermore, do not charge the watch while the manual power save function is activated. First cancel the manual power save function before charging.

• The manual power save function is activated by setting the city name to "C65" and the time difference to "0" while following the procedure described in in section 13 on Using Zone Setting, and then returning the crown to the norma position.

(Analog Display)

Each hand stops moving at its current location.

(Digital Display)

• The entire digital display is not lit.

Notes:

• None of the button operations function in any mode.
• The mode does not change even when the mode hand is attempted to be moved by turning the crown.

Each hand rapidly advances to the current time and Manual Power Save is canceled when the crown is pulled out to the secondclick.

Return the crown to the normal position after canceling the manual power save function.

Each hand rapidly advances to the current time and begins to move.
- The digital display reappears simultaneous to resumption of power generation, and the alarm sounds for the set duration. However, the chronograph returns to the reset state and the timer switches to the initial setting display.

[Charge Indicator]

The charge indicator provides a simple graphic indication in digital display area 2 of the amount of charge remaining in the secondary battery.

Fully charged

Sufficiently charged

Low charge

Hardly any charge

When none of the bars of the graphic display are lit, the secondary battery has essentially become completely discharged and the second hand begins two-second interval movement. Since the watch will stop due to insufficient charging if this state continues for about 1.5 days, sufficiently charge the watch by exposing to light.

16. General Reference for Charging Times

The time required for recharging varies according to the model of the watch (color of the dial, etc.). The following times are shown below to serve only as a reference.

• Recharging time refers to the amount of time the watch is continuously exposed to light.

Illuminance (lx)	Environment	Charging time
		Charging time for 1 day of operation	Charging time from the stopped state to one-second interval movement	Charging time from stopped state to fully charged
500	Inside an ordinary office	2 hours 30 minutes	15 hours	182 hours
1,000	60-70 cm (24-28 in.) under fluorescent light (30 W)	1 hour	8 hours	87 hours
3,000	20 cm (8 in.) under fluorescent light (30 W)	20 minutes	3 hours	29 hours
10,000	Outdoors, cloudy weather	6 minutes	1 hour 30 minutes	9 hours
100,000	Outdoors, summer, under direct sunlight	3 minutes	50 minutes	5 hours

Full recharging time: Time required for recharging the watch from the stopped state to fully charged. Charging time for 1 day of operation: Time required for recharging the watch to run for 1 day at one-second interval movement.

17. Notes Regarding Handling of this Watch

• Please note that if you routinely 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.

Notes: Charging Precautions

• Avoid recharging at high temperatures (over about 60^ / 140^ ) since this may result in damage to the watch as a result of reaching excessively high temperatures.

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.

18. Replacing The Secondary Battery

Unlike ordinary batteries, the secondary battery 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 secondary battery 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.

[Calculation function]

Note the following points when using this function. Use the calculation function of this watch only as a guide. These scales do not indicate the position of the decimal point.

Speed index

Outer scale

(distance scale)

Inner scale

(Time acale)

A. Navigational calculation

1) Time required

Example: Obtain the time required for the fight of an aircraft at 180 knots for 450 nautical miles.

Answer. Align "18" on the outer scale with the SPEED INDEX (▲) on the inner scale. Then, "45" on the outer scale corresponds to "2:30" on the inner scale (time scale). Thus, the time required for the flight is 2 hours and 30 minutes.

2) Knots (air speed)

Example: Obtain the knots (air speed) for 240 nautical miles with a flight time of 1 hour and 20 minutes.

Answer. Align "24" on the outer scale with "1:20" on the inner scale (time scale). Then, the SPEED INDEX () on the inner scale corresponds to "18" on the outer scale. Thus, the air speed for the flight is 180 knots.

3) Flight distance

Example: Obtain the air distance when the air speed is 210 knots and the flight time is 40 minutes.

Answer. Align "21" on the outer scale with the SPEED INDEX (▲) on the inner scale. Then, "40" on the inner scale corresponds to "14" on the outer scale. Thus, the air distance of the flight is 140 nautical miles.

4) Rate of fuel consumption

Example: Obtain the rate of fuel consumption (gallons / hour) when the flight time is 30 minutes and the fuel consumption is 120 gallons.

Answer. Align "12" on the outer scale with "30" on the inner scale. Then, the SPEED INDEX (▲) on the inner scale corresponds to "24" on the outer scale. Thus, the fuel consumption is 240 gallons per hour.

5) Fuel consumption

Example: Obtain the fuel consumption required for a flight when the vate of fuel consumption is 250 gallons per hour and the flight time is 6 hours.

Answer. Align "25" on the outer scale with the SPEED INDEX (▲) on the inner scale. Then, "6:00" on the inner scale (time scale) corresponds to "15" on the outer scale. Thus, the fuel consumption is 1,500 gallons.

6) Estimated flight time

Example: Obtain the estimated flight time when the vate of fuel consumption is 220 gallons per hour and the aircraft has 550 gallons of fuel.

Answer. Align "22" on the outer scale with the SPEED INDEX (▲) on the inner scale. Then, "55" on the outer scale corresponds to "2:30" on the inner scale (time scale), Thus, the estimated flight time is 2 hours and 30 minutes.

7) Difference in altitude

The difference in altitude can be obtained from the rate of descent and the descent time.

Example: Obtain the difference in altitude when an aircraft continues descending for 23 minutes at a rate of 250 feet per minute.

Answer. Align "25" on the outer scale with "10" on the inner scale. Then, "23" on the inner scale corresponds to "57.5" on the outer scale. Thus, the difference in altitude is 5,750 feet.

8) Rate of climb (or descent)

The rate of climb (or descent) can be obtained from the time required to reach an altitude.

Example: Obtain the rate of climb when an aircraft reaches an altitude of 7,500 feet after climbing for 16 minutes.

Answer. Align "75" on the outer scale with "16" on the inner scale. Then, "10" on the inner scale corresponds to "47" on the outer scale. Thus, the rate of climb is 470 per minute.

9) Time of climb (or descent)

The time required for climb can be obtained from the altitude to be reached and the rate of climb (or descent).

Example: Obtain the time of climb when an aircraft is to climb to 6,300 feet at a rate of 550 feet per minute.

Answer. Align "55" on the outer scale with "10" on the inner scale. Then, "63" on the outer scale corresponds to "11.5" on the inner scale. Thus, the time of climb is 11 minutes and 30 seconds.

10) Conversion

Example: Convert 30 statuts miles into nautical miles and kilometers.

Operation: Align "30" on the outer scale with STAT (▲) on the inner scale. Then, NAUT (▲) on the inner scale corresponds to "26" nautical miles on the outer scale, and "12 km" (s) on the inner scale corresponds to "48.2" km on the outer scale.

B. General Calculation Functions

1) Multiplication

Example: 20 × 15

Operation: Align "20" on the outer scale with "10" on the inner scale. Then, "15" on the inner scale corresponds to "30" on the outer scale. Take into account the position of the decimal point and add one zero to obtain 300. Note that with the scales of this watch, the position of the decimal point cannot be obtained.

2) Division

Example: 250/20

Operation: Align "25" on the outer scale with "20" on the inner scale. Then, "10" on the inner scale corresponds to "12.5" on the outer scale. Take into account the position of the decimal point to obtain 12.5.

3) Proportion

Example: 30 / 20 = 60 / x

Operation: Align "30" on the outer scale with "20" on the inner scale. Then, "60" on the outer scale corresponds to "40" on the inner scale. At this point, the proportion for every value on the inner and outer scales is 30:20.

4) Square root

Example: Square root of 225

Operation: Turn the outer scale showly and find a value that corresponds to both "22.5" on the outer scale and "10" on the inner scale. In this example, "22.5" on the outer scale corresponds to "15" on the inner scale, and "10" on the inner scale corresponds to "15" on the outer scale. Thus, the answer is 15.

20. Precautions

CAUTION: Water-resistance performance

There are several types of water-resistant watches, as shown in the following table.

The unit "bar" is roughly equal to 1 atmosphere.

• WATER RESIST(ANT) xx bar may also be indicated as W.R. xx bar.

Indication		Specification
Dial	Case (Case back)
WATER RESIST or no indication	WATER RESIST(ANT)	Water-resistant to 3 atmospheres
WR 50 or WATER RESIST 50	WATER RESIST(ANT) 5 bar or WATER RESIST(ANT)	Water-resistant to 5 atmospheres
WR 100/200 or WATER RESIST 100/200	WATER RESIST(ANT) 10bar/20 bar or WATER RESIST(ANT)	Water-resistant to 10 / 20 atmospheres

For correct use within the design limits of the watch, confirm the level of water-resistance of your watch, as indicated on the dial and case, and consult the table.

Examples of use

• Water-resistance for daily use (to 3 atmospheres): This type of watch is 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

• 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.
• 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.
