hours daily. In case most of your work is at
a desk and there is little arm movement, it
may result in insucient winding. In such
cases, please wind manually.

wind the spring.
If the watch has stopped, rotating the crown
around 40 times will result in sucient
winding of the spring.

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.

Precautions
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.
• Take o your watch before going to bed.
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 the crown or any push buttons when the watch 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 aer a long time, consult your dealer
or Authorized Service Center for inspection and/or repair.

19
Precautions
• 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 o 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 o.
CAUTION When Wearing your Watch
<Band>
• Leather, genuine skin and rubber (urethane) bands will deteriorate over time due to perspiration, body oils and
dirt. Be sure to replace the band periodically.
• e durability of a leather band may be aected when wet (fading, peeling of adhesive), owing to the properties
of the material. Moreover, wet leather may cause a rash.
• It is recommended to take o 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.
