1. Main Features
this analog/digital combination solar watch works on
Citizen’s environmentally clean Eco-Drive system.
the Eco-Drive converts the energy oflight to electrical
energy using the solar charger set in the dial of the
watch, generating power to operate various analog
and digital functions. the watch also has the world
time display function. by operating the button, you
can easily check the time and day in 24 major cities
of the world.
2. Before Use
If the solar battery is insufficiently charged, you
cannot operate the watch as explained in the
instruction manual.
To recharge, place the watch under a fluorescent or
incandescent lamp at a distance of approx. 20 cm for
approx. 40hours, or under direct sunlight for approx.
one hour. The secondary battery is an
environmentally clean energy source since it
does not contain mercury or other pollutive
materials. Once the battery is charged to the full,
the watch will keep on running for 2.3 months
without recharging.
• For Trouble Free Use
Be sure that the solar battery is sufficiently
charged to ensure smooth operation of Alarm,
Chronograph and other functions. The watch has an
Overcharge Prevention function. You can charge the
4. Special Functions of the Solar Powered Watch
If solar battery becomes insufficiently charged, a
warning function comes into operation and the
display changes, as below.
(When the watch is
insufficiently charged)
(1) If the watch has been set
to Time or Calendar
mode, it will keep the
mode in use when
Insufficient Recharging
Warning was shown.
• In this state, you can
switch modes between
Time and Calendar and
adjust display.
(2) If the watch has been set
to alarm, Chronograph,
Timer or Zone Set mode,
it will automatically
switch to Time display mode.
(3) If Chronograph measurement or Timer
countdown is in progress, the watch will
automatically stop operation and switch to time
display mode from reset mode.
(4) Alarm will not sound
(5) “CHARGE” will appear in digital display-1.
(When the watch is sufficiently recharged)
(1) Insufficient Recharging Warning (“CHARGE”
mark) disappears and the watch returns to normal
time or Calendar mode.
(2)
Mode switching by the M button will become
active when the Insufficient recharging
warning has released. In this case, readjust
the display of each mode before use.
Insufficient Recharging Warning Feature
Analog display: Second hand starts advancing 2
seconds at a time indicating the
watch is insufficiently charged.
The watch keeps correct time even
when power charge is insufficient.
the watch will stop unless this
condition is not corrected within
about 3 days.
Digital display: “CHARGE” appears in digital
display-1.
Quick Start Feature
The watch will stop if solar battery has completely
lost its power charge. When watch face is exposed to
light, Second hand will start advancing irregularly
hitch movement after approx. 10 seconds (Time
Reset Indicator). Length of time required for
restarting Second hand will depend on intensity of
light. If light is blocked when solar battery is not fully
charged, the watch will stop again.
Time Setting Indication Feature
If the watch is exposed to light after it has stopped, it
will activate the Quick Start function and start moving
again. However, Second hand will show hitch
movement to indicate the need to reset to the correct
time. In this case, reset time. Otherwise, Second
hand will continue to show irregular movement. If
time is reset when power charge is too low,
Insufficient Recharging Warning and Time Reset
Indicator (Second hand hitch movement) will appear
again.
• Be sure to set Analog Time, Calendar and other
modes after adjusting display to the correct time.
Overcharging Prevention Feature
When secondary battery is charged fully,
Overcharging Prevention function will activate
automatically.
Special care for using solar watch
Make sure that solar battery is always charged to
sufficient level. When you are wearing clothes with
long sleeves, power charge may become too low
because the watch is not exposed to light.
• Always keep the watch exposed to light when not
using it. This will assure correct running of the watch.
WARNING Never use batteries other than the
secondary battery specified for this watch. The
watch is not structurally designed to operate on any
other type of battery. However, if by chance a silver
battery or other batteries are used, their is a danger
that the battery will be overcharged and burst
causing damage to the watch and the user. When
replacing secondary battery, be sure to use the
designated product.
Recharging solar watch
CAUTION The watch will be damaged during
recharging if it gets too hot (about 60C/140F or
more). Avoid recharging at high temperatures. Don’t
recharge near an incandescent lamp, halogen lamp
and other high temperature light sources or on a car
dashboard and other heat accumulating places.
• Solar battery may not be fully charged if placed in a
dimly lit place.
Time required for recharging
Recharging time differs depending on model of the
watch (colour of the dial).

9. Precautions
1) Resistance to water
3) Avoid wet conditions
Do not operate the crown or pushbuttons when your
watch is wet.
4) Avoid strong shocks
5) Avoid strong magnetic fields
6) Avoid Static Electricity
The integrated circuits used in your watch are
sensitive to static electricity. If exposed to intense
static electricity, the watch’s display may lose its
accuracy.
7) Avoid chemicals, and corrosive gases
Avoid wearing your watch in the presence of strong
chemicals, solvents and gases. If your watch comes
in contact with materials such as gasoline, benzine,
paint thinner, alcohol, spray cosmetics, nailpolish,
nail polish remover, adhesives or paint, discoloration,
deterioration or damage to the case, band or their
components may occur.
Check the chart to determine the water resistant
properties of this watch.
Refer to the table for water-resistance performance
after checking the water-resistance characteristics
inscribed on the face and back of the watch.
• Always set the crown in the normal position.
• While working with water or using it as a waterresistant sports watch, if the watch is dipped in
seawater or after a lot of sweating, please rinse it
well in fresh water and dry it thoroughly with a soft
cloth.
• Leather straps have characteristics that may affect
durability after getting wet.
• Because there is always air inside the watch, when
the air temperature outside remains temporarily,
there is no problem, but if it doesn’t disappear after
a long period of time, please consult the shop you
purchased it from or another Citizen dealer.
2) Avoid temperature extremes
Avoid leaving your watch in direct sunlight or in
extremely warm locations for long periods of time.
8) Photosensitive eyeglasses
The watch’s digital display may become difficult to
read clearly when wearing photosensitive
eyeglasses or sunglasses such as ski goggles and
tinted fishing glasses. This problem can be corrected
by turning your wrist slightly to change the angle
between the eye and watch, providing a clear view of
the display.
9) Keep your watch clean
Wipe off any water and moisture that adheres to the
case, glass or band with a soft, clean cloth. Any dirt
left on the case or band may cause skin rash. A
watchband will easily become soiled with dust and
perspiration since it is in direct contact with the skin.
Even a stainless steel or gold-plated band may begin
to corrode if it has not been cleaned for a long period
of time. Mesh bands, because the mesh is very fine,
will lose their particular “flexibility” if they are left
soiled for a long time.
Metal watchbands are usually washed with a brush
in mild, soapy water, rinsed and wiped with a soft,
absorbent cloth to make sure all water is removed.
Exercise care to prevent any water from getting
inside your watch when the band is washed.
10) Periodic inspection
Getting your watch checked once every year or two
is recommended to ensure long use and trouble-free
operation.
11) Watch bands
Metal bands: Metal watch bands can be cleaned with
a toothbrush, soap and water.
Leather bands: Wipe off the front side of the band
with a soft dry cloth, and remove stains on the back
side of the band with a cloth moistened in alcohol.
Plastic or rubber bands: Wash in water. (Avoid using
solvents as they may cause the band to dissolve).
12) Be sure to keep secondary batteries out of
reach of infants and small children. Should
accidental ingestion occur, consult a doctor at
once.

Water Resistance
The water-resistant quality of our timepieces is offered in varying degrees depending on the model. This
ranges from non-water resistant models to those suitable for SCUBA diving. Water resistance of our
timepieces is measured in BAR or Barometric Pressure. Each BAR of pressure is equal to 14.5 pounds per
square inch of pressure.
Water resistance is measured when the watch is at a static, or motionless state. As the watch is moved in
water, such as from the motion of swimming, pressure is added from velocity. While you may be swimming in
a pool at surface level, the watch may be experiencing forces equal to that of 100 feet of water pressure
(3 BAR). Diving into a pool can cause forces on the watch to exceed those pressures. As such, you
should always allow a margin of safety when exposing your watch to moisture. Never "push the limit" of
the degree of water resistance of your timepiece.
A primary factor to keep in mind about water resistance is that periodic maintenance is needed to
maintain original factory specifications for water resistance. When a watch is new, it meets
specifications for water resistance as indicated on the case back. However, as the watch ages, the
gaskets that seal the watch become dry and brittle, diminishing its water resistant quality. Exposure to
environments such as chlorinated pools, salt water or soaps from showering can accelerate drying of the
gaskets. We recommend that the gaskets be changed at least every 18 to 24 months to maintain the water
resistant quality of your timepiece. If the watch is frequently exposed to chlorinated pools, soaps salt
water, etc., we recommend that the gaskets be changed on a yearly basis.
From time to time, you may notice condensation that appears then goes away after a short period of time.
This is a normal occurrence and happens primarily from sudden temperature changes. When there are sudden
temperature changes such as entering a cool building from the hot out of doors, or jumping into pool on a
hot day the watch may fog. Conversely, if you go to the cold outdoors from a warm building, fogging may
occur. As long as the fogging clears in a short period of time, there is no need for concern.
Be sure the crown is completely pushed in prior to any contact with moisture. If your model is equipped
with a screw down crown, be sure it is properly seated against the case. Do not operate the crown or any
push button when the watch is wet as this may allow the entrance of moisture. . If at anytime, you notice
moisture in your timepiece that does not clear in a short period of time, you should send your timepiece
as soon as possible to the nearest Authorized Service Center for inspection.
You can determine the level of water resistance of our watches from the markings on your case-back.
Additionally, models that are water resistant to 100 or 200 meters have an indication on the dial as
well. The case-backs and dials are normally marked as follows:
The case back has no indication of water resistance
This indicates the watch is a non water-resistant model and is not designed for contact with moisture at
all. Caution should be exercised to avoid any contact with moisture, such as when washing your hands or
from a rainstorm.
“Water Resist”
This watch is designed to withstand water from accidental splashing, such as from washing your hands or
rain. Any submersion into water may result in the entrance of moisture.
“Water Resist 10BAR” or “W.R. 10BAR”, Dial marked “WR100”
This watch is designed to withstand water pressure up to 333 feet. This includes water exposure from
accidental splashing and rain, but also from showering, swimming in a pool and snorkeling. Be sure to
rinse the watch with fresh water after exposure to a chlorinated pool, salt water, soaps, etc. After
rinsing with fresh water, be sure to dry the exterior with a soft cloth.
“Water Resist 20BAR” or “W.R. 20BAR”, Dial marked “WR200”
This watch is designed to withstand water pressure up to 666 feet. This includes all exposure to water up
to and including recreational SCUBA diving. Be sure to rinse the watch with fresh water after exposure to
a chlorinated pool, salt water, soaps, etc. After rinsing with fresh water, be sure to dry the exterior
with a soft cloth.
Special Note about Jacuzzis and Hot Tubs
The various components used in the manufacture and assembly of your watch expand at various rates. This
results in a loss of the sealing capabilities of gaskets, which may allow moisture to enter. In addition,
heat from these sources can cause deformation of certain materials leading to mechanical failures. For
these reasons, you should remove your watch before entering a hot tub or Jacuzzi.
