
Be sure to keep all user documentation handy for future reference.
 Your watch may differ somewhat from the one shown in the illustration.
 Some models may use a combination of hands and rotating disks to indicate
information. The word "hand" in this section is used to mean both analog hands
and rotating disks.

 Take care that you set the correct AM
or PM time.
 When changing the time, move the
minute hand four or fi ve minutes past
your fi nal setting, and then back it up
to the setting you want.
Crown Operations
Some water-resistant models (100 meters, 200 meters)
have a screw-in crown. When you need to perform a crown
operation, rotate it towards you to unscrew it. Then pull
the crown out. Avoid applying undue force when pulling.
The watch loses its water resistance while the crown is
unscrewed. After performing a crown operation, fully screw
the crown back in.
If your watch has a rotary bezel...
You can rotate the bezel to align its ▼ mark with the
minute hand. Then you will be able to tell how much
time has elapsed since aligning the ▼ mark.

 Do not use this watch for scuba diving or other types of diving that requires air tanks.
 Watches that do not have WATER RESIST or WATER RESISTANT marked on the back
cover are not protected against the effects of sweat. Avoid using such a watch under
conditions where it will be exposed to large amounts of sweat or moisture, or to direct
splashing with water.
 Even if a watch is water-resistant, do not operate its buttons or crown while it is
submersed in water or wet.

Even if a watch is water-resistant, avoid wearing it in the bath or in areas where detergents
(soap, shampoo, etc.) are being used. Such conditions can reduce water resistance.

After submersion in seawater, use plain water to rinse all salt and dirt from the watch.
 To maintain water resistance, have the gaskets of your watch replaced periodically (about
once every two or three years).

A trained technician will know how to check your watch for proper water resistance

Natural Leather and Imitation Leather Bands
 Allowing the watch to remain in contact with other items or storing it together with other
items while it is wet for long periods can cause the color of the other items to transfer to the
natural leather or imitation leather band of the watch. Be sure to dry off the watch thoroughly
before storing it and make sure it is not in contact with other items.

Leaving a leather band where it is exposed to direct sunlight (ultraviolet rays) for long periods
or failure to clean dirt from a leather band for long periods can cause it to become discolored.

Metal Components
Yes
 Failure to clean dirt from a metal band can lead to formation of rust, even if the band is
stainless steel or plated. If the watch is exposed to sweat or water, wipe it thoroughly with
Yes
a soft, absorbent cloth and then store it in a well-ventilated location to dry.
 To clean the band, use a soft toothbrush or similar tool to scrub it with a weak solution of
Yes
water and a mild neutral detergent. Take care to avoid getting solution on the watch case.
Yes
Bacteria and Odor Resistant Band
 The bacteria and odor resistant band protects against odor generated by the formation
of bacteria from sweat, which ensures good comfort and hygiene. In order to ensure
maximum bacteria and odor resistance, keep the band clean. Use an absorbent soft cloth
to wipe the band clean of dirt, sweat, and moisture. The bacteria and odor resistant band
suppresses the formation of organisms and bacteria. It does not protect against rash due
to allergic reaction, etc.
