• Clouding of glass
Since there is some moisture in a watch, if
outside temperature is lower than inside the
watch, the glass may get fogged. If the fog clears
soon, it is not a problem. If it does not clear soon,
however, have it checked immediatly.
2. Protective Packings
• Packings incorporated in this watch (for its
caseback, crown and glass) prevent entering of
water, dust and other foreign matters into the
watch to protect its functions. Periodical
replacement of these packings (every 2 years
approximately) is recommended since they may
become subject to brittleness and/or their
elasticity may decrease after long time use.
3. Use for diving
Be sure to check the following points when you
use this watch for diving.
a. Before diving
• Isn’t it a time to replace the power cell?
• The time has been properly set.
• The crown is properly in lock position.
• The register-ring properly rotates counterclockwise.
It does not rotate clockwise (never force to rotate
it at this time).
• There are no scatches in the wrist band and no
cracks nor chipped portions in the glass of the
watch. Also, the wrist band should be fastened
tightly to the watch case.
b. While diving
• Never operate the crown in water.
• Be careful not to hit the watch against a rock or
equipment.
c. After diving
• Wash the watch with fresh water to prevent rust
formation due to sea water.
• Wipe off water droplets adhering to the watch
after washing.
Watch Band
• If the watch band shows cracks, replace it with a
new band.
• When replacing the watch band, also replace the
spring bars connecting the watch and band.
Temperature
Avoid exposing the watch to direct sunlight or leaving
it in extremely hot or cold locations for a long period
of time.
• This will cause malfuctioning and shorten the life
of the battery.
• This may cause your watch to gain or lose time
and affect its other functions.
Shock
• This watch will withstand the bumps and jars
normally occured in daily use and while playing
such non-contact sports as golf and catchball.
• Dropping the wathc on the floor or otherwise
imparting severe shock to it may cause
malfunctioning or damage.
Magnetic Fields
This watch is antimagnetic up to 60 gauss and not
affected by the magnetic fields produced by ordinary
household electric appliances. If used in the
immediate vicinity of strong magnetism, however,
the watch’s functions may temporarily be affected.
Static Electricity
The integrated circuits use in the watch are
sensitive to static electricity. If exposed to intense
static electricity, the watch’s display may lose its
accuracy.
Chemicals and Gases
Avoid wearing the watch in the presence of strong
chemicals or gases. If the watch comes in contact
with such solvents as thinner and benzine or
products containing materials such as gasoline,
polish detergent or adhesive, its components may
discolour, disslove, or crack. Be especially careful to
avoid chemicals. The watchcase or band may
discolour if they come in contact with mercury from
a broken thermometer or other equipment.
Natural Light
The luminous paint used for this watch emits no
hazardous radiation at all, and is not harmful to
human beings or to the environment.
It emits light stored during exposure to daylight or
artificial light. (For example: if you place the watch
under 500-lux light source, such as an ordinary
desk lamp, for more than 10 minutes, it will emit
light for about three to five hours). However, the
brightness of the light will diminish as the watch
remains in darkness. In addition, depending on the
brightness of the daytime light source and the
distance between the watch and the light source,
the length of time the watch emits light will vary.
Note that if the light stored in the watch is
insufficient, the watch may not emit much light or
will lose brightness quickly. If you will be using the
watch underwater, be sure it is sufficiently exposed
to light beforehand, or use a watch with an
underwater light.
Safekeeping
If you do not use the watch for an extended period
of time, wipe of perspiration, soil and moisture
thoroughly and keep it in a place not exposed to
extremely high or low temperatures or high humidity.
Don’t leave a dead battery in the watch for a long
time and be sure to replace it with a new one. If the
battery fluid leaks out, it may damage movement
components.
Keep Your Watch Clean
Wipe off soil and moisture from the glass with a
soft, absorbent cloth. If you wear the watch when
the back side of the case and the watchband is
soiled, they may cause a skin rash as they come in
direct contact with your skin. Keep your watch clean
also to aviod staining of cuffs.
