Radio Wave Reception Procedures
• The watch can receive radio waves in time mode (TME, three positions) and local time
mode (L-TM). It cannot receive radio waves in the other modes.
Automatic reception
• It is not necessary to operate buttons to perform automatic reception.
The watch will receive the radio waves at 2 a.m. every day. If a radio wave cannot be
received at 2 a.m., it will try again automatically at 4 a.m. and the time and date will
be adjusted.
On demand reception (manual reception)
• Radio waves can be received at any time.
Use this function when automatic reception is impossible due to changes in the
reception environment. Do not move the watch during on demand reception
to ensure proper reception of the radio waves. (This may take up to approx.
13 minutes.)
162

<For best reception>
An antenna for receiving the radio waves is located inside the watch at the 6:00 position.
For best reception, it is recommended to point the 6:00 position of the watch to the
direction of the radio wave transmitter. The reception level may be affected by the
surroundings in which the watch is being used. Place the watch in different locations
and directions while paying attention to the reception level (H, M or L) to find the most
receptive location or orientation to give a reception level of H or M.
[NOTE] The watch can receive radio waves in the
time mode (TME, three positions) and
local time mode (L-TM). The watch cannot
receive radio waves in any other mode.
• Remove the watch from your wrist and place on a stable surface near a window where
the radio wave can be easily received. Do not move the watch during reception.
• Reception may be difficult due to the surroundings or metal shielding. When inside
a building and so on, place the watch as close to a window as possible for good
reception.
<Time required for reception>
Reception takes about 2 to 13 minutes. If reception has failed due to environmental
factors, the watch might return to the normal indication after about 60 seconds.

A. Navigation Calculator
1. Calculation of time required
Example: How long does it take an airplane flying at 180 knots to fly a
distance of 450 nautical miles?
Solution: Set the 18 mark on the outside scale to the SPEED INDEX ( ).
At this time, the point on the inside scale that is aligned with 45 on
the outside scale indicates (2:30), and the answer is 2 hours and 30
minutes.
204
2. Speed (ground speed) calculation
Example: What is the speed (ground speed) of an airplane when it takes
1 hour and 20 minutes to fly a distance of 240 nautical miles?
Solution: Align the 24 on the outside scale with 1:20 (80) on the inside scale.
At this time, 18 is aligned with the SPEED INDEX ( ) on the
inside scale, and the answer is 180 knots.
205
3. Flying distance calculation
Example: What is the flying distance traveled in 40 minutes at a speed of
210 knots?
Solution: Align the 21 on the outside scale with the SPEED INDEX ( ) of
the inside scale. The 40 of the inside scale is now pointing to 14,
and the answer is 140 nautical miles.
206
4. Fuel consumption rate calculation
Example: If 120 gallons of fuel are consumed in 30 minutes’ flying time, what
is the fuel consumption rate?
Solution: Align the 12 of the outside scale with 30 of the inside scale.
The SPEED INDEX ( ) now points to 24, and the answer is
240 gallons per hour.
207
5. Fuel consumption calculation
Example: How much fuel is consumed in 6 hours at a fuel consumption rate of
250 gallons per hour?
Solution: Align the 25 on the outside scale with the SPEED INDEX ( ) of
the inside scale. The 6:00 is aligned with 15, and the answer is 1500
gallons.
208
6. Maximum flying hours
Example: With a fuel consumption rate of 220 gallons per hour and a fuel
supply of 550 gallons, what is the maximum number of flying
hours?
Solution: Align the 22 on the outside scale with the SPEED INDEX ( ) of
the inside scale. The 55 of the outside scale is now aligned with
2:30, and the answer is 2 hours and 30 minutes.
209
7. Conversion
Example: How do you convert 30 miles into nautical miles and kilometers?
Solution: Align the 30 on the outside scale with the STAT ( ) mark on the
inside scale.
At this time, 26 nautical miles is aligned at the NAUT ( ) mark on
the inside scale, while the answer of 48.2 kilometers is aligned at
the kilometers ( ) on the inside scale.
210
B. General calculation functions
1. Multiplication
Example: 20×15
Solution: Align 20 on the outside scale with 10 on the inside scale, and read
the outside scale at the 30 mark which is aligned with 15 of the
inside scale. Figure the number of decimal places, and the answer is
300.
Remember: decimal places cannot be read on this scale.
211
2. Division
Example: 250÷20
Solution: Align 25 on the outside scale with 20 on the inside scale. On the
outside scale read the 12.5 mark that is aligned with 10 on the inside
scale. Figure the number of decimal places, and the answer is 12.5.
212
3. Reading ratios
Example: 30/20 = 60/x
Solution: Align 30 on the outside scale with 20 on the inside scale.
At this time, the answer of 40 can be read from the inside scale
corresponding to 60 on the outside scale.
In addition, the ratio of the value on the outside scale to the value on
the inside scale is 30:20 at all positions on the scales.
213
4. Determining square root
Example: What is the square root of 225?
Solution: Rotate the scales so that the value on the inside scale corresponding
to 22.5 on the outside scale is equal to the value on the outside scale
corresponding to 10 on the inside scale, and read off the answer of
15 at that location.
11. Solar Power Function
This watch uses a secondary battery to store electrical energy.
Once the watch has been fully charged, it will maintain its accuracy for about 8 months
when operating normally (when not in the power saving mode). In the power saving
mode, it will maintain its accuracy for about 2 year.
<Ensuring best operation of the watch>
Keep the watch regularly charged for best results. Charge watch by exposing the watch
face (which contains the solar cell) to direct sunlight or to a fluorescent lighting.
<Regularly charge the watch>
• Wearing clothes with long sleeves makes it difficult for the watch to get the necessary
light, resulting in insufficient charging. Be particularly aware of the need for regular
charging during the winter.
• Placing the watch near a window where its face can receive sunlight or near another
source of light when you are not wearing it will ensure that the watch is regularly
charged, allowing it to maintain the correct time.
214
215
12. Characteristics of the Solar Powered Watch
When the watch is insufficiently charged, the indication will be changed as follows:
[Normal indication]
[Insufficient charge warning]
The watch has been
insufficiently charged
because the watch face,
which contains the solar
cell, has not received
sufficient light.
*1. When the watch stopped due to an insufficient charging
• It takes at least 30 minutes to recharge sufficiently to perform recovery automatic
reception, even if the watch is being exposed to light. After recovery, refer to
“Guide to Charging Time” and sufficiently charge the watch.
*2. If the watch failed to perform recovery automatic reception
• The time is incorrect even if the second hand moves at 1-second intervals, so after
fully charging the watch, set the time manually or perform on demand reception.
[Recovery automatic reception]
The insufficient charge
warning (a 2-second interval
movement) continues for more
than 3 days.
The watch will
stop due to
an insufficient
charging.
Sufficiently charge by
exposing the watch
face, which contains
the solar cell to light.*1
2-second interval
movement
The second hand starts moving
at 2-second intervals.
216
When a radio wave has been
successfully received*2
When the watch is recharged sufficiently, it will
receive the radio wave automatically once.
217
A. Power saving function
<Power saving function>
B. Insufficient charge warning function
[Power saving mode]
If the solar cell has not received at least 30 minutes of
continuous light, the second hand will stop at the 12:00
position and the watch will enter power saving mode.
• The other hands will continue to move as normal.
• If the watch is warning about insufficient charging warning
function (2-seconds interval movement), the watch will
enter power saving mode when it is not receiving light.
<Cancelling the power saving function>
The power saving function will be automatically cancelled when the solar cell is
exposed to sufficient light.
• After the power saving function has been cancelled, the second hand will move
clockwise to the current time and return to 1-second interval movement.
• If the watch is insufficiently charged, the second hand will begin the 2-second interval
movement. When this happens, sufficiently charge the watch so that it returns to
1-second interval movement.
[NOTE] After the power saving function has been cancelled, press the lower right
button (A) to check the reception status. If the reception status indicates NO as
a result, use on demand reception to set the correct time before using the watch.
218
The second hand’s movement changes from 1-second
intervals to 2-second intervals. The watch will stop due
to an insufficient charging about 3 days after starting the
2-second interval movement.
[NOTE] If the second hand is moving at 2-second
intervals:
2-second
1 The time cannot be corrected manually, or by using interval movement
automatic reception or on demand reception.
2 The watch can be used only in the time mode. You will
not be able to use the other modes.
C. Overcharging prevention function
Whenever the secondary battery becomes fully charged by exposing the solar cell to
light, the overcharging prevention function is automatically activated to prevent the
battery from being charged further.
No matter how much the watch is charged, it will not affect the secondary battery,
timekeeping, functions or performance of the watch.
219
13. Guide to Charging Time for the Solar Powered Watch
The charging time varies according to the model (including the color of the watch face).
The following data should only be used as a guideline.
Illuminance
(lx)
3,000
10,000
100,000
Environment
20 cm (8 in.) beneath a
30 W florescent light
Under cloudy skies
Direct summer sunlight
Time required to store
energy for one day of
Time required to fully
charge from stopped operation when the second
status (approximate) hand is moving at 1-second
intervals (approximate)
200 hours
40 minutes
60 hours
30 hours
12 minutes
3 minutes
The table can be used to find an estimate of the amount of energy that the watch can
store depending on the environment and amount of time the watch is charged.
For example, you can see that the energy that can be stored when the watch is subjected
to approximately 4 hours of light under cloudy skies is sufficient to operate the watch for
about 20 days.
220
More energy can be stored by allowing even brighter light to strike the watch face for an
even longer time. The watch can be efficiently charged in less time under sunlight than
under fluorescent lighting.
• Although the watch becomes hot when placed under direct
sunlight for an extended period, there is no problem as long
as the temperature does not exceed 60°C (140°F).
[NOTE] A fully charged battery will run the watch for about 8 months without further
charging. The watch will maintain its accuracy for about 2 years when running
in the power saving mode. Charge the watch every day, as it will take a
long time to recharge it, as is indicated in the table, when it stops due to an
insufficient charging.
It is recommended that the watch is charged in direct sunlight for a long time
once a month.
221
14. Handling Your Solar Powered Watch
CAUTION
Charging precautions
• Overheating while charging can cause the watch exterior to become discolored, the
watch to deform or the movement to be damaged.
• Do not charge the watch in a high-temperature environment (about 60°C/140°F or
more).
Example) Charging close to incandescent lighting, halogen lamps, or other lighting
sources that easily become hot.
Charging on surfaces that can easily become hot, such as a car dashboard.
• When charging with incandescent lighting, halogen lamps, or other lighting sources
that easily become hot, place the watch at least 50 cm (20 in.) away from the source to
avoid overheating.
222
WARNING
Handling the secondary battery
• Do not remove the secondary battery from the watch yourself, unless unavoidable.
If you must remove the battery, store it out of reach of children to avoid accidental
ingestion. If the secondary battery is ingested, consult a doctor immediately.
WARNING
Changing the secondary battery
• Although the secondary battery should never need to be changed, in rare instances,
the watch may be unable to be charged due to a problem with the battery. If a problem
occurs, have the watch repaired as soon as possible.
223
15. Troubleshooting
Problem
<Radio wave reception function>
If you believe your watch may be inoperative, consult the following chart:
Problem
Check
Remedy
• Radio waves cannot be
received.
• Is the watch in the time mode
(TME) or local time mode
(L-TM)?
• Does the second hand move
to the RX (reception standby)
position?
• Pull out the crown to position 1 and
turn to select the time mode (TME) or
local time mode (L-TM).
• Press and hold the lower right button
(A) until the second hand has reached
the RX position.
• Radio wave cannot
be received (where
reception is possible).
• Are there objects nearby that
could block radio waves or
generate noise?
• Are you attempting to receive
the radio wave in a location far
from a window?
• Avoid objects that block radio waves
or generate noise. Try to receive radio
waves by pointing the 6:00 position
in the direction of the radio wave
transmitter.
Find a location conducive to radio
wave reception by paying close
attention to the reception level showed
by the second hand as you change the
watch location, direction and angle.
(p. 172)
224
Check
Remedy
• The second hand
is indicating the RX
position, but the watch
does not receive radio
waves.
• Is the watch still receiving the
radio wave, and is the second
hand indicating the reception
level (H, M or L)?
• Wait until reception has been
completed (until the second hand
has returned to the 1-second interval
movement).
• The watch can receive
the radio wave, but
it does not show the
correct time.
• Is the reference position set
correctly?
• Confirm the reference position.
(p. 198)
<Eco-Drive>
Problem
• The second hand is
moving at 2-second
intervals.
Check
• Did you charge the watch
sufficiently in sunlight?
Remedy
• Charge the watch sufficiently, as
indicated in “Guide to Charging
Time”. (p. 220)
• The watch has
stopped.
• The watch does
not work even after
charging.
• If the watch does not work even after
charging, contact the Citizen Service
Center.

WARNING
Water-resistance performance
• 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, do not use while swimming.
• 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, do not use while skin diving or scuba diving.
• Upgraded water-resistance for daily use (to 10/20 atmospheres): You may wear the
watch while skin diving; however, do not use while 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 that the crown is locked securely.
• Do not operate the crown or button when the watch is wet. Water may enter the watch
and compromise water-resistance.
• The durability of a leather band may be affected when wet, owing to the properties of
the material. In the case of a watch of upgraded water resistance for daily use that is
frequently used in water, fading, peeling of adhesive or other problems may occur. It is
therefore recommended to use another type of band (metal or rubber band).
228
• 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, take the watch to your nearest 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
• Leaving dust and dirt deposited between the case and crown may result in difficulty in
pulling the crown out. Turn 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.
229
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 band, 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.
CAUTION: Avoid using solvents (thinner, benzine, etc.), as they may damage 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
car dashboard. 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 speaker of a cellular
phone. If this has occurred, move the watch away from the magnet and reset the time.
230
• 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.
<Periodical inspections>
• Your watch needs inspection once in every two or three years for safety and long use.
• Because the ability to resist water degrades as the years pass in the case of a waterresistant watch, part replacement is required in order to maintain water-resistance.
Replace the packing and spring as necessary.
• Ask for Citizen genuine parts upon replacement. In addition to replacement, other
parts may require inspection and repair. For details on replacement and repair charges,
please contact the store where you purchased your watch or a Citizen Service Center.
