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 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.

Precautionary items and usage limitations
CAUTION Battery replacement
• Do not recharge the used battery.
• Do not throw the used battery into the fire.
• Keep the battery out of the reach of small children.
• If the battery is accidentally swallowed, consult a doctor immediately.
• 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.
CAUTION 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 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.
CAUTION Precautions
• 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.
