CONTENTS
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 also equipped with
numerous functions including a perpetual calendar that changes the date automatically
(changes the number of years from the most recent leap year, month, date and day
automatically until February 28, 2100 including leap years), a daily alarm that can be
set based on a 24 hour clock, and a local time function that enables setting of time
differences in one hour units.
second intervals). When the crown is pulled out to Position 2 in the time mode, the
second hand stops causing the time to be incorrect. In addition, since the set time,
date, alarm time and so forth will end up changing if the crown is pulled out to Position
2 in each mode, be careful not to pull out the crown too strongly.
Refer to “5. Switching the Mode (Display Function)” for information on how to
properly switch the watch to each mode.

2. Before Using
<Be careful not to pull the crown too far out when switching the mode.>
The mode of this watch can be changed with the crown pulled out to Position 1.
If the crown is pulled out to Position 2, the second hand will move to the 0 seconds
position and the watch will enter the correction mode for each mode (when in the time
mode or alarm mode; when in the calendar mode, the second hand moves to the month
display, and when in the local time mode, the second hand continues to move at 1-

This watch is a solar-powered watch. Please fully charge the watch before
using by exposing it to light by referring to “11. General Reference for
Charging Times”.
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 1.5 years
without additional charging (when the power save feature is operating).
V Power Save Feature:
When power generation stops as a result of light not shining on the solar cell during
the time (TME) or local time (L-TM) mode, the power save feature is activated and
the second hand stops at the 0 seconds position to save power. The 24 hour hand,
hour hand and minute hand continue to move normally. When light once again
begins to shine on the solar cell, the power save feature is canceled and the second
hand rapidly moves to the current time and returns to moving at 1-second intervals.
Although varying according to the design, the power save feature is activated
when light does not shine continuously on the solar cell for 30 minutes or more,
and the second hand has reached the 0 seconds position.

<Proper Use of this Watch>
To use this watch comfortably, make sure to charge it before it stops running
completely. Since there is no risk of overcharging no matter how much the watch is
charged (Over Charge Prevention Feature), it is recommended that the watch be
charged every day.

minutes and then moving forward by 5 minutes), the hour hand and minute hand
enter the correction mode.
16
8. Click (turn) the crown.
• Turn the crown by one click to the right causes the hour hand and minute hand to
advance by 1/4 minute (and 4 clicks cause them to advance by 1 minute).
• Turn the crown by one click to the left to move back the hour hand and minute
hand by 1/4 minute (and 4 clicks cause them to move back by 1 minute).
• Continuously turning the crown causes the hour hand and minute hand to advance
continuously. Turn the crown by one click to the right or left to stop the hour hand
and minute hand from advancing. The hour and minute hands will advance by 24
hours and then stop automatically if they are not interrupted.
• First stop the hands at about 12:00 and then slowly move them one step at a time to
correctly align them at the 12:00 position.
9. Press button (A).
• After the function hand and date complete a demonstration movement (the function
hand rotates backward by 180 degrees and then returns to its original position,
while the date moves in coordination with the function hand), the watch enters the
calendar correction mode.
10. Turn the crown to align the function hand at “SUN” immediately after the date has
changed to “1”.
• Turning the crown by one click to the right advances the function hand by one step.
• Turning the crown by one click to the left moves back the function hand by one
step.
17
• Turning the crown continuously causes the function hand to advance continuously.
Turn the crown by one click to the right or left to stop the function hand from
advancing.
• The date changes by one day when the function hand completes four
revolutions. Turn the crown to the right to advance the function hand by
clockwise rotation and continue to advance the function hand until “1” is
displayed for the date.
• When setting the date by advancing the function hand counter-clockwise, first
move back the function hand until “31” is displayed for the date, and then advance
the function hand by clockwise rotation until “1” is displayed for the date.
• Correctly set the function hand to “SUN” immediately after the date has changed to
“1”. Once the date has changed to “1”, immediately interrupt movement of the
function hand and align it with “SUN” on the scale by slowly moving it one step at
a time.
Note: Pressing button (A) causes the watch to enter the second hand reference
position setting mode again.
11. Return the crown to the normal position and press button (A).
• The date and each hand return to the local time display.
• Reference position correction can also be terminated by returning the crown to the
normal position and pressing button (A) following correction of the second hand or
hour and minute hands.
Example: If the crown is returned to the normal position and button (A) is pressed
after correcting seconds, reference position correction is terminated and
the watch returns to the local time display without correcting the
reference positions for the hour hand, minute hand, function hand or
date.

10. Functions Unique to Solar-Powered Watches
When the watch becomes insufficiently charged, the watch display changes as shown
below. When the watch has changed normal hand movement to the insufficient charge
warning display, this indicates that that the watch is insufficiently charged. Allow light
to shine on the solar cell until the watch returns to 1-second interval movement. Even
after the watch has returned to 1-second interval movement, sufficiently charge the
watch by exposing it to light by referring to “11. General Reference for Charging
Times” to ensure that the watch is used comfortably.
35
[Power Save Feature]
The second hand stops at
the 0 seconds position to
save power.
[Normal Time Display]
When the watch stops
generating power as a
result of the solar cell
not being exposed to

The time is incorrect since
the watch has stopped as a
result of being insufficiently

the correct time.
36
[Insufficient Charge
Warning Display]
Charge the watch by allowing light to shine on the solar cell until the watch
begins to run. In the case the watch has stopped as a result of being
insufficiently charged, a minimum of 30 minutes are required until the watch
begins to run again even if light shines on the solar cell. Sufficiently charge the
watch by referring to “11. General Reference for Charging Times”.
37
<Insufficient Charge Warning Feature>
When the watch becomes insufficiently charged, the
watch switches to the time mode regardless of which
mode is displayed at that time, and the second hand
begins to move at 2-second intervals to indicate that the
2 seconds
watch is insufficiently charged.
• Although the watch continues to run normally at this
2 seconds
time, the watch ends up stopping if it remains
insufficiently charged for about 3 days. Sufficiently charge the watch by exposing to
light so that the second hand returns to 1-second interval movement. Continue to
charge the watch even after the second hand returns to 1-second interval movement to
ensure that the watch can be used comfortably. There no need to worry about
overcharging since it is equipped with an over charge prevention feature.
• Although the watch will begin to run when light is allowed to shine on the solar cell
after it has stopped as a result of being insufficiently charged, since the time is
incorrect, reset the watch to the correct time after sufficiently charging.
Notes:
• Alarm time and ON/OFF status continued to be stored in memory. However, the
alarm tone will not sound even if the alarm is set (ON).
• The set time (time difference) is retained in memory for the local time.
38
• Crown (mode switching) and button operations will not function.
• The time (including alarm and local time) and date cannot be corrected.
<Over Charge Prevention Feature>
When the secondary battery becomes fully charged as result of light shining into the
watch dial (solar cell), the over charge prevention feature is activated automatically to
prevent the battery from being charged further. This prevents the performance of the
solar cell and secondary battery from deteriorating no matter how much the watch is
charged, and lets you expose the watch to light without worrying about overcharging.
<Power Save Feature>
When power is no longer generated as a result of light
not shining continuously for 30 minutes or more on the
solar cell during the time or local time mode, the second
hand moves to the 0 seconds position and stops and the
power save feature is activated to reduce current
consumption.
• The 24 hour hand, hour hand and minute hand continue
to keep the correct time even when the watch is in the
power save mode.
39
• The calendar is corrected in coordination with the 24 hour hand, hour hand and
minute hand.
• When the watch has been sufficiently charged and power generation resumes, the
second hand rapidly advances to the current seconds and begins 1-second interval
movement.
• The second hand begins 2-second interval movement if the watch is insufficiently
charged (insufficient charge warning feature). Allow light to shine on the solar cell to
fully charge the watch.
11. General Reference for Charging Times
Recharging time varies according to the watch model (such as the color of the dial).
The times in the table below should therefore only be used as a rough reference.
* Charging time refers to the amount of time during which the watch is continuously
exposed to light.

Note:
• The watch will continue to operate for about 7 months without additional charging
once it has been fully charged. It will continue to keep time for about 1.5 years when
the Power Save feature has been activated. However, once the watch has stopped as a
result of being insufficiently charged, a considerable amount of time is required until
it starts to run again as indicated in the table above. It is therefore recommended to
charge your watch everyday. Furthermore, it is recommended to charge your watch
by exposing to direct sunlight once a month.
42
12. Solar-Powered Watch Handling Precautions
<Try to keep the watch charged at all times.>
Please note that if you frequently wear long sleeves, the watch can easily become
insufficiently charged because of being hidden and not exposed to light.
• When you take the watch off, try to place in as bright a location as possible so that it
will always be charged and continue to run properly at all times.
CAUTION Charging Precautions
• Avoid charging the watch at high temperatures (about 60°C/140°F or higher) since
allowing the watch to reach a high temperature during charging can cause
deformation or discoloration of the dial, solar cell and other external components as
well as a malfunction of mechanical components.
Examples: Charging by placing the watch too close to a light source that may
become hot such as an incandescent lamp or halogen lamp, or charging
by placing the watch on an automobile dashboard that can easily reach a
high temperature.
• When charging the watch with an incandescent lamp, halogen lamp or other light
source that may reach a high temperature, always make sure to place the watch at
least 50 cm (20 in) away from the light source to prevent the watch from reaching a
high temperature.
43
WARNING Handling of Secondary Battery
• Never attempt to remove the secondary battery from the watch. If the secondary
battery must unavoidably be removed, store it out of the reach of small children to
prevent accidental swallowing.
• If the secondary battery should happen to be swallowed, consult a physician
immediately and seek medical attention.
13. Replacing the Secondary Battery
Unlike ordinary silver-based batteries, the secondary battery used in this watch does not
have to be periodically replaced since it is able to be charged and discharged
repeatedly.
WARNING Only Use the Specified Secondary Battery
• Never use a secondary battery other than the genuine secondary battery used in this
watch. Even if another type of secondary battery is installed in the watch, the watch
structure does not permit its operation. In cases in which a different secondary battery
such as a silver battery is forcibly installed in the watch and charged, overcharging
may occur that will eventually cause the secondary battery to rupture. This can result
in the risk of the watch being damaged or injury to the wearer. When the secondary
battery is replaced, always make sure to use the specified secondary battery.

14. All-Reset
This watch may not function properly as a result of being subjected to the effects of
static electricity, strong impact and so forth. When this happens, perform the All-Reset
and Reference Position Alignment procedures described below. When performing the
all-reset procedure, first make sure the watch is sufficiently charged and the second
hand is moving at 1-second intervals. 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.
[All-Reset Procedure]
1. Pull the crown out to Position 1 (the
second hand rapidly advances to the
30 seconds position and waits).
2. Turn the crown to align the mode
hand to the local time mode [L-TM].
3. Pull the crown out to Position 2
(local time setting position).
46
Button (A)
• The second hand rapidly moves to the current time and begins 1-second interval
movement.
4. Press buttons (A) and (B) simultaneously.
• Following a confirmation tone, each hand performs a demonstration movement.
5. This completes the all-reset procedure. Next, perform the reference position
alignment procedure for each hand and the calendar by referring to “4. Hand
Reference Position Check and Correction”.
Furthermore, if performing the reference position alignment procedure after
performing the all-reset procedure, perform steps 6 through 10 of the “Reference
Position Correction” described in “4. Hand Reference Position Check and
Correction”.
6. After having aligned the reference position, correctly reset the time, date and other
modes before using the watch.

• 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
• Be sure to use the watch with the crown pressed in (normal position). If your watch
has a screw-lock type crown, be sure to tighten the crown completely.
• 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.
50
• 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.
51
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.
52
• 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.
Periodical inspections
Your watch needs inspection once in every two or three years for safety and long use.
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 Citizen geuine parts upon replacement.
