Water resistance
WARNING Water resistance
• 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 be worn while skin diving or scuba 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 diving or saturated diving using helium gas.

Precautionary items and usage limitations
Battery replacement
CAUTION
• Do not recharge the used battery.
• Do not throw the used battery into the fire.
• Do not ingest battery – Chemical Burn Hazard.
• This product contains a coin/button cell battery. If the coin/button cell battery is swallowed, it can cause
severe internal burns in just 2 hours and can lead to death.
• Keep new and used batteries away from children.
• If the battery compartment does not close securely, stop using the product and keep it away from children.
• If you think batteries might have been swallowed or placed inside any part of the body, seek immediate
medical attention.
• Do not disassemble, customize or heat the battery. It may result in a serious accident.
• Leaving a used battery in the watch may damage it through leakage and result in malfunction. Replace the
battery soon.
• When replacing the battery, always make sure to use the designated one.
• Do not replace the battery with any other than the specified one. If it is replaced with an incorrect battery,
it may explode or the watch may have malfunction.
To Avoid Injury
CAUTION
• 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 others.
• Do NOT wear your watch while in a sauna or other location where your watch may become excessively
hot, since there is the risk of burns.
• Be careful when putting on and taking off your watch, since there is a risk of damaging your fingernails,
depending on the manner in which the band is fastened.
Precautions
CAUTION
• Always use the watch with the crown pushed in (normal position). If the crown is of the screw lock-type,
make sure it is securely locked.
• Do not operate (use the crown and/or buttons) the watch when it is wet. Water may enter the watch
causing damage to vital components.
• If water enters the watch or the watch fogs up and does not clear up even after a long time, consult your
dealer or an authorized service center for inspection and/or repair.
• Even if your watch has a high level of water resistance, please be careful of the following.
- If your watch is immersed in sea water, rinse thoroughly with fresh water and wipe with a dry cloth.
- Do not pour water from a tap directly onto your watch.
- 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.
When Wearing Your Watch

• 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.
NO
NO
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 (excluding products containing the band adjustment tool).
Consult an authorized service center. Other shops may charge for, or may not provide, the service.
<Temperature>
• The watch may stop or the function of the watch may be impaired in extremely high or low temperature.
• Do not use or store the watch in an environment with excessive heat or cold, or with conditions which
may cause battery leakage, heating, explosion or flaming.
