Please charge the watch fully before use
by exposing it to light.
When the watch does not operate according to the
instruction manual, it is insufficiently charged.
Charge the watch for at least 3 hours approximately
20 cm (8 in) away from a fluorescent or incandescent
lamp (30 W) as a light source. When charging, do
not place the watch too close to the light source to
prevent the watch from becoming too hot.
* When charging the watch under direct sunfight,
charge for at least 50 minutes.

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.

[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

<Digital Display in Each Mode>
• 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.
Two second interval
movement
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.
49
• 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>
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.
50
[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.
51
(Digital Display)
The initial setting display (12 hours, 00 minutes, 00 seconds, UTC or January 1
SA) flashes in the time or calendar mode.
<Canceling the Time Setting Warning Function>
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.
52
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.
53
[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.
<Canceling Power Save 1>
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 onesecond interval movement.
• The digital display reappears simultaneous to resumption of power generation.
54
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.
55
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.
<Canceling Power Save 2>
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.
56
<Setting Manual Power Save>
• 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 <Registration
of Arbitrary City and Time Difference> 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.
<Canceling Manual Power Save>
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.

16. General Reference for Charging Times
[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.
<Interpretation of Secondary Battery Charge Levels>
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.
Charging time
Illuminance Environment
(lx)
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 twosecond 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.

17. Notes Regarding Handling of this Watch
18. Replacing The Secondary Battery
<Try to keep the watch charged at all times.>
Unlike ordinary batteries, the secondary battery used in this watch doesn't
have to be periodically replaced due to repeated charging and discharging.
• 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°C / 140°F) 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.
60
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.

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.
55
Outer scale
(distance scale)
Inner scale
(Time acale)
1
1) Time required
Example: Obtain the time required fo the fight of an aircraft at 180 knots for 450 nautical
miles.
Answer. Align “18” on the outer scale with the SPEED INDEX (Y) 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 (Y) on the inner scale corresponds to “18” on the outer
scale. Thus, the air speed for the flight is 180 knots.
3) Flight diatance
Example: Obtain the air distance when the air speed is 210 knots and the flight time is 40
minutes.
62
Answer. Align “21” on the outer scale with the SPEED INDEX (Y) 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 (Y) 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 (Y) 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 (Y) 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.
63
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 correspons 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 (Y) on the inner scale. Then, NAUT
(Y) 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.
64
B. General Calculation Functions
1) Multiplication
Example: 20 M 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 eccount 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.

• 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.
• 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.
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.
68
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
69
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
70
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.
