your face or in the rain, but is not to be immersed in water.
• 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.
• For a metallic, plastic or rubber watchband, wash any dirt off with water. Remove the small
amounts of dirt trapped between the crevices of the metallic band with a soft brush. If your watch
is not water resistant, be sure not to get the case of the watch wet.
Precautions and usage limitations
Water resistance
To Avoid Injury
• Be particularly careful when wearing your watch while holding a small child, to avoid injury.
• Be particularly careful when engaged in strenuous exercise or work, to avoid injury to yourself and
• DO NOT wear your watch while in a sauna, jacuzzi or other location where it may become
excessively hot. This may result in burns to the wearer and/or malfunction of your watch.
• Be careful when putting on or taking off your watch since there is a risk of pinching your skin or
damaging your fingernails depending on the manner in which the band is fastened.
• Always wear your watch with the crown pushed in to the normal position. If your crown is a screw
down type, be sure it is properly screwed down (locked) to the case.
• Do not operate the crown or any buttons when the watch is wet. This may allow the entrance of
moisture and cause damage to sensitive components.
• If water enters the watch or the watch fogs up and does not clear up even after a long time, consult
Authorized Service Center for inspection and/or repair.
• If a watch of upgraded water resistance for daily use is immersed in sea water or subjected to
excessive perspiration, thoroughly rinse with fresh water and wipe completely dry with a soft cloth.
• 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.
When Wearing Your Watch
• The durability of a leather, cloth, or natural skin strap may be affected by moisture and
perspiration. Moreover, wet leather may cause a rash. Be sure to keep your strap dry and clean.
• It is recommended to take off the watch if it gets wet, even if the watch itself is water-resistant.
• Do not wear your watch too tightly. Try to leave enough space between the watch and your skin to
allow adequate ventilation.
Precautions and usage limitations
• A rubber type strap may become stained by dyes or soils found in clothing and other accessories.
Since these stains may become permanent, take caution when wearing your watch with items that
may transfer color (articles of clothing, purses, dyed bracelets, etc.).
• Solvents, moisture and perspiration may cause the strap to deteriorate. Be sure to replace a strap
that has become dried, brittle, or cracked to prevent loss due to strap failure.
• 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.
<Static Electricity>
• The integrated circuits (IC) used in quartz watches are sensitive to static electricity. Please note that
the watch may malfunction if exposed to intense static electricity.
• Analog type quartz watches are powered by a motor that utilizes a small magnet. The operation
of this motor can be disturbed if the watch is subjected to magnetic items resulting in the
malfunction of the watch. Do not allow the watch to come into close proximity to magnetic items
such as “health” bracelets or necklaces, coin trays, latches found in cabinets and refrigerators,
certain clasps of handbags and cell phone pouches, cell phone speakers, certain sporting
accessories, MRI equipment, etc.
Precautions and usage limitations
<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.
<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 in contact with the watch, they may cause discoloration, deterioration and
damage materials of the watch. Be careful when handling these chemicals. Contact with mercury
such as that used in thermometers may also cause discoloration of the band and case.
• The case and band of the watch come in to direct contact with the skin. This may result in
unnoticed accumulations of dirt and foreign matter caused by normal wear. Accumulated matter
may cause rust, discoloration, and premature wear. Be sure to regularly clean your watch with
a soft cloth. If severe accumulations occur, you may need to have your case and/or bracelet
professionally cleaned.
• In some instances, accumulations of dirt and foreign matter may cause skin reactions. This may
also occur due to certain allergies beyond our control. If this occurs, immediately discontinue use
of your watch and consult your physician.
• Leather, cloth, and other natural skin straps may become discolored or brittle from moisture,
perspiration and/or accumulated dirt. To maximize the life of your strap, be sure to keep your
leather band clean and dry by wiping it with a soft cloth each day.
Always Keep Your Watch Clean
• 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.
Note: Do not operate the crown or any buttons when the watch is wet.
• The case and band of the watch come into direct contact with the skin in the same manner as
undergarments. Corrosion of the metal or unnoticed soiling such as that caused by perspiration
and dirt can soil sleeves and other portions of clothing. Keep your watch clean at all times.
Precautions and usage limitations
Caring for Your Watch
• Wipe any dirt or moisture such as perspiration from the case and crystal with a soft 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.
Precautions and usage limitations
Daily maintenance
• 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.
• Wipe off dirt, perspiration, and water from the case and glass with a clean soft cloth occasionally.
• To clean a metal, plastic, or rubber watchband, wash away dirt with water. Use a soft brush to
remove dust and dirt stuck in the gaps in a metal band.
• Do not use a polishing type of cloth as this may damage the surface and certain treatments.
• Do not use solvents (thinner, benzine, etc.), as they may damage the finish.
Periodical inspections
Your watch needs an inspection once every two or three years for safety and longer usage. To keep
your watch water-resistant, the gaskets and other components need to be replaced regularly. Other
parts need to be inspected and replaced if necessary.
Always ask for genuine Citizen parts upon replacement.
About the Watch with Luminous Paint
Your watch may feature luminous treatment to the dial and hands to aid you in reading the watch
in dimly lit environments. This luminous treatment stores light from both natural and artificial
sources. It is free from any radioactive substance or any other material that may be harmful to the
environment or human body.
• The light emission of the luminous material gradually decreases as time passes.
• The duration and amount of light emitted will vary depending on the brightness, type of and
distance from the light source, exposure time and amount/size of luminous treatment.
• When not exposed to a light source, light emission from the luminous treatment will start off
bright and gradually diminish over a period of hours. The duration of visible light emission will
vary with type of and duration of light exposure as well as size of luminous features of your watch.
