Charging your watch
This watch has a solar cell under the dial and stores the power
generated by the cell in its built-in rechargeable cell.
The cell is charged by exposing the dial to light such as direct
sunlight or fluorescent lamps.
For optimal performance, be sure to:
•
Put the watch in a location where the dial is exposed to bright
light such as by the window even when it is not used.
•
Expose its dial to direct sunlight for 5 or 6 hours at least every
week.
•
Avoid leaving it in dark places for long periods of time.
CAUTI ON
• Do not charge the watch at a high temperature (about 60°C (140°F) or higher)
as doing so may cause movement malfunction.
• If the watch is obscured from light by long sleeves frequently, supplemental
charging may be needed to ensure continual operation.
• The watch stops charging automatically after finishing (overcharging prevention
function). The function prevents damage to performance of the watch and
rechargeable cell due to overcharging.
When the watch reaches a low charge state (insufficient charge warning
function)
When the power reserve becomes low, the second hand
moves once every two seconds. This is the insufficient
charge warning function. Be sure to fully charge your watch
immediately as outlined above.
• When the watch is sufficiently charged, the second hand
will move normally.
• If you do not charge the watch for 3 days or longer after the insufficient charge
warning movement has begun, the watch will be depleted of all power and stop.
During the insufficient charge warning state
The time and date are indicated correctly.

Before using this watch
Use of the Bluetooth communication technology is not legally permitted in some
countries or regions. Visit our web site below to confirm the list of countries
where Bluetooth is legally available.
http://www.citizenwatch-global.com/support/
• Using this watch in a country where it is not permitted may be punished under
its law.
• Communication using Bluetooth may be monitored intentionally or accidentally.
Do not use this watch for important communication or any communication
involving human lives.
CITIZEN Bluetooth Watch W410 Instruction manual
Eco-Drive watch handling precautions
<Always Make Sure to Recharge Frequently>
• For optimal performance, your watch should remain fully charged.
• Long sleeves may inhibit light transmission to your watch. This may result in your watch loosing
charge. In these cases supplemental charging may be necessary.
• When you take off the watch, place it in a bright location to ensure optimal performance..
CAUTION
• Do not charge the watch at a high temperature (about 60°C (140°F) or
higher) as doing so may cause the movement to malfunction.
Examples:
-Charging the watch too close to a light source which generates a large
amount of heat such as an incandescent lamp or halogen lamp. When
charging under an incandescent lamp, be sure to leave 50 cm (20 inches)
or more between the lamp and the watch to avoid exposing the watch to
excessive heat.
-Charging the watch in a location where the temperature may become
extremely high such as on the dashboard of a vehicle.
<Replacement of Rechargeable Cell>
• This watch utilizes a special rechargeable cell that does not require periodical replacement.
However power consumption may increase after using the watch for a number of years due to wear of
internal components and deterioration of oils. This may cause stored power to be depleted at a faster rate.
WARNING
• The rechargeable cell should never be removed from the watch. If for any reason it becomes necessary
to remove the rechargeable cell from the watch, keep out of the reach of children to prevent accidental
swallowing. If the rechargeable cell is accidentally swallowed, consult a doctor immediately.
• Do not dispose of the rechargeable cell with ordinary garbage. Please follow the instructions of your
municipality regarding collection of batteries to prevent the risk of fire or environmental contamination.
WARNING
• Never use a battery other than the rechargeable cell specified for use in this watch.
Although the watch structure is designed so that it will not operate when another type of battery is
installed, if a conventional watch battery or other type of battery is installed in the watch and the watch is
recharged, there is the risk of overcharging which may cause the battery to rupture.
This can cause damage to the watch and injury to the wearer. When replacing the rechargeable cell, always
make sure to use the designated rechargeable cell.
Recharging Precautions
Handling of Rechargeable Cell
Use Only the Specified Battery
Water resistance
WARNING
• Refer to the watch dial and/or the case back for the indication of the water resistance of your watch. The
following chart provides examples of use for reference to ensure that your watch is used properly. (The
unit “1bar” is roughly equal to 1 atmosphere.)
• WATER RESIST(ANT) ××bar may also be indicated as W.R.××bar.
• Non-water resistant models are not designed to come into contact with any moisture. Take care not to
expose a watch with this rating to any type of moisture.
• Water resistance for daily use (to 3 atmospheres) means the watch is water resistant for occasional
accidental splashing.
• Upgraded water-resistance for daily use (to 5 atmospheres) means that the watch may be worn while
swimming, but is not to worn while skin diving.
• Upgraded water-resistance for daily use (to 10/20 atmospheres) means that the watch may be worn while
skin diving, but not while scuba or saturated diving using helium gas.

-Take off your watch before taking a bath.
• 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, push button, etc.) may come
off.
CAUTION
<Band>
• Leather bands and rubber (urethane) bands will deteriorate over time due to perspiration or dirt.
In addition, they are made of natural material and will be worn, deformed and discolored over time. It is
recommended to replace the band periodically.
• The durability of a leather band may be affected when wet (fading, peeling of adhesive), owing to the
properties of the material. Moreover, wet leather may cause a rash.
• Do not stain a leather band with substances containing volatile materials, bleach, alcohol (including
cosmetics). Discoloration and premature aging may be occurred. Ultraviolet light such as direct sunlight
may cause discoloration or deformation.
• It is recommended to take off the watch if it gets wet, even if the watch itself is water-resistant.
• Do not wear the band too tightly. Try to leave enough space between the band and your skin to allow
adequate ventilation.
• The rubber (urethane) band may be stained by dyes or soil present in or on clothing or other accessories.
Since these stains may not be removable, caution is required when wearing your watch with items that
tend to easily transfer color (articles of clothing, purses, etc.). In addition, the band may be deteriorated by
solvents or moisture in the air. Replace with a new one when it has lost elasticity or become cracked.
• Please request adjustment or repair of the band in the following cases:
-You notice an abnormality with the band due to corrosion.
-The pin of the band is protruding.
• We recommend seeking the assistance of an experienced watch technician for sizing of your watch. If
adjustment is not done correctly, the bracelet may unexpectedly become detached leading to loss of your
watch or injury.
Consult an authorized service center.
<Temperature>
• The watch may stop or the function of the watch may be impaired in extremely high or low temperature.
Do not use the watch in places where the temperature is outside the operating temperature range as stated
in the specifications.
<Magnetism>
• Analog quartz watches are powered by a step motor that uses a magnet. Subjecting the watch to strong
magnetism from the outside can cause the motor to operate improperly and prevent the watch from
keeping time accurately.
Do not allow the watch to come into close proximity to magnetic health devices (magnetic necklaces,
magnetic elastic bands, etc.) or the magnets used in the latches of refrigerator doors, clasps used in
handbags, the speaker of a cell phone, electromagnetic cooking devices and so on.
<Strong Shock>
• Avoid dropping the watch or subjecting it to other strong impact. It may cause malfunctions and/or
performance deterioration as well as damage to the case and bracelet.
<Static Electricity>
• The integrated circuits (IC) used in quartz watches are sensitive to static electricity. Please note the watch
may operate erratically or not at all if exposed to intense static electricity.
<Chemicals, Corrosive Gasses and Mercury>
• If paint thinner, benzene or other solvents or products containing these solvents (including gasoline,
nail-polish remover, cresol, bathroom cleaners and adhesives, water repellent, etc.) are allowed to come
into contact with the watch, they may discolor, dissolve or crack the materials. Be careful when handling
these chemicals. Contact with mercury such as that used in thermometers may also cause discoloration of
the band and case.
<Protective Stickers>
• Be sure to remove any protective stickers that may be on your watch (case back, band, clasp, etc.).
Otherwise, perspiration or moisture may enter the gaps between the protective stickers and the parts,
which may result in a skin rash and/or corrosion of the metal parts.
CAUTION
• Rotate the crown while it is pressed in fully and press the buttons periodically so they do not become
stuck due to accumulations of foreign matter.
• The case and band of the watch come into direct contact with the skin. Corrosion of the metal or
accumulated foreign matter may result in black residue coming from the bracelet when exposed to
moisture or perspiration unnoticed soiling such as that caused by perspiration. Be sure to keep your watch
clean at all times.
• Be sure to periodically clean the bracelet and case of your watch to remove accumulated dirt and foreign
matter. In rare circumstances, accumulated dirt, foreign matter may cause irritation with the skin. If you
notice this, discontinue wearing the watch and consult your physician.
• Be sure to periodically clean foreign matter and accumulated materials from the metal band, synthetic
rubber strap (polyurethane) and/or metal case using a soft brush and mild soap. Be careful not to allow
moisture on the case if your watch is not water resistant.
• Leather bands may become discolored by perspiration or dirt. Always keep your leather band clean by
wiping with a dry cloth.

CITIZEN Bluetooth Watch W410 Instruction manual
Caring for Your Watch
• Wipe any dirt or moisture such as perspiration from the case and crystal with a soft cloth.
• For a metallic, plastic or synthetic rubber (polyurethane) band, clean it with soap and a soft toothbrush.
Be sure to thoroughly rinse the band after cleaning to remove any soap residue.
• For a leather band, wipe off dirt using a dry cloth.
• If you will not be using your watch for an extended period of time, carefully wipe off any perspiration,
dirt or moisture and store in a proper location, avoiding locations subject to excessively high or low
temperatures and high humidity.
When Luminous Paint is used for your watch
The paint on the dial and hands helps you with reading the time in a dark place. The luminous paint
stores light (daylight or artificial light) and glows in a dark place.
It is free from any radioactive substance or any other material harmful to a human body or
environment.
• The light emission gradually becomes weaker as time passes.
• The duration of the light (“glow”) will vary depending on the brightness, types of and distance from a
light source, exposure time, and the amount of the paint.
• The paint may not glow and/or may dissipate quickly if exposure to light was not sufficient.
