■HANDLING CAUTIONS
Immediately stop wearing the watch in the following
cases.
○If the watch body or band becomes edged by corrosion etc.
○If the pins protrude from the band.
※Immediately consult the retailer from whom the watch was purchased or
SEIKO CUSTOMER SERVICE CENTER.
Keep the watch and accessories out of the reach of
babies and children.
Care should be taken to prevent a baby or a child accidentally swallowing the
accessories. If a baby or child swallows the battery or accessories, immediately
consult a doctor, as it will be harmful to the health of the baby or child.
Do not remove the battery from the watch.
Replacement of the battery requires professional knowledge and skill. Please ask
the retailer from whom the watch was purchased for battery replacement.
Do not recharge the battery, as doing so can generate heat which may cause
bursting, leakage or ignition.
WARNING
Do not use the watch in scuba diving or
saturation diving.
The various tightened inspections under simulated harsh
environment, which are usually required for watches designed for
scuba diving or saturation diving, have not been conducted on
the water-resistant watch with the BAR (barometric pressure)
display. For diving, use special watches for diving.
To indicate the risks of serious consequences such as severe
injuries unless the following safety regulations are strictly
observed.
WARNING
Avoid wearing or storing the watch in the following places.
○Places where volatile agents (cosmetics such as polish remover, bug repellent,
thinners, etc.) are vaporizing.
○
Places where the temperature drops below 5 ºC or rises above 35 ºC for a long time.
○Places of high humidity.○
Places affected by strong magnetism or static electricity.
○Dusty places. ○ Places affected by strong vibrations.
※Do not leave a dead battery within the watch for a long time as leakage may occur.
If you observe any allergic symptoms or skin irritation
Stop wearing the watch immediately and consult a specialist such as a
dermatologist or an allergist.
Other cautions
○
Replacement of the metal band requires professional knowledge and skill.
Please ask the retailer from whom the watch was purchased for replacement of
the metal band, as there is a risk of hand or nger injury and fear of losing parts.
○Do not disassemble or tamper with the watch.
○Keep the watch out of the reach of babies and children. Extra care should be
taken to avoid risks of any injury or allergic rash or itching that may be caused
when they touch the watch.
○When disposing of used batteries, follow the instructions of your local
authorities.
○
If your watch is of the fob or pendant type, the strap or chain attached to the watch
may damage your clothes, or injure the hand, neck, or other parts of your body.
○
Please keep in mind that if a watch is taken off and placed down as it is, the case
back, the band and the clasp will rub against each other possibly causing scratches
on the case back. We recommend placing a soft cloth between the case back, the
band and the clasp after taking off your watch.
CAUTIONS To indicate the risks of light injuries or material damages unless
the following safety regulations are strictly observed.
Do not leave moisture, sweat and dirt on the
watch for a long time.
Be aware of a risk that a water resistant watch may lessen its water
resistant performance because of deterioration of the adhesive on
the glass or gasket, or the development of rust on stainless steel.
Do not pour running water directly from the faucet.
The water pressure of tap water from a faucet is high enough to
degrade the water resistant performance of a water resistant watch
for everyday life.
CAUTIONS
Do not turn or pull out the crown when the watch is wet.
Water may get inside of the watch.
※
If the inner surface of the glass is clouded with condensation or water droplets
appear inside of the watch for a long time, the water resistant performance of
the watch is deteriorated. Immediately consult the retailer from whom the
watch was purchased or SEIKO CUSTOMER SERVICE CENTER.
Do not wear the watch while taking a bath or a sauna.
Steam, soap or some components of a hot spring may accelerate
the deterioration of water resistant performance of the watch.

English
Daily care
The watch requires good daily care
○Do not wash the watch when its crown is at the extended position.
○Wipe away moisture, sweat or dirt with a soft cloth.
○After soaking the watch in seawater, be sure to wash the watch in clean
pure water and wipe it dry carefully.
※If your watch is rated as “non-water resistant” or “water resistant for daily use”, do not
wash the watch.
Performance and type → page 20. Water resistance → page 20.
Turn the crown from time to time
○In order to prevent corrosion of the crown, turn the crown from time to time.
○The same practice should be applied to a screw lock type crown.
Crown → page 7.
Band
The band touches the skin directly and becomes dirty from sweat or dust.
Therefore, lack of care may accelerate deterioration of the band or cause skin
irritation or stain on the sleeve edge. The watch requires a lot of attention for long
usage.
Metallic band
○Moisture, sweat or soil will cause rust even on a stainless steel band if they
are left for a long time.
○
Lack of care may cause a yellowish or gold stain on the lower sleeve edge of shirts.
○Wipe off moisture, sweat or soil with a soft cloth as soon as possible.
○To clean the soil around the joint gaps of the band, wipe it out in water and
then brush it off with a soft toothbrush (Protect the watch body from water
splashes by wrapping it up in plastic wrap etc.).
○Because some titanium bracelets use pins made of stainless steel, which
has outstanding strength, rust may form in the stainless steel parts.
○If rust advances, pins may poke out or drop out, and the watch case may
fall off the bracelet, or the clasp may not open.
○If a pin is poking out, personal injury may result. In such a case, refrain from
using the watch and request repair.
Leather band
○A leather band is susceptible to discoloration and deterioration from
moisture, sweat and direct sunlight.
○
Wipe off moisture and sweat as soon as possible by gently blotting them up with a dry cloth.
○Do not expose the watch to direct sunlight for a long time.
○Please take care when wearing a watch with light-colored band, as dirt is
likely to show up.
○
Refrain from wearing a leather band watch other than Aqua Free bands while
bathing, swimming, and when working with water even if the watch itself is
water-resistant enforced for daily use (10-BAR/20-BAR water resistant).
Polyurethane band
○A polyurethane band is susceptible to discoloration from light, and may be
deteriorated by solvent or atmospheric humidity.
○Especially a translucent, white, or pale colored band easily adsorbs other
colors, resulting in color smears or discoloration.
○Wash out dirt in water and clean it off with a dry cloth. (Protect the watch
body from water splashes by wrapping it up in plastic wrap etc.)
○ When the band becomes less exible, have the band replaced with a new
one. If you continue to use the band as it is, the band may develop cracks
or become brittle over time.
Notes on skin irritation and allergy
Skin irritation caused by a band has various reasons such as allergy to metals
or leathers, or skin reactions against friction on dust or the band itself.
Notes on the length of the band
Adjust the band to allow a little clearance with your wrist to ensure
proper airflow. When wearing the watch, leave enough room to
insert a nger between the band and your wrist.

If the watch becomes magnetized and its accuracy deteriorates to an extent
exceeding the specified rate under normal use, the watch may need to be
demagnetized. In this case, you will be charged for demagnetization and
accuracy readjustment even if it happens within the guarantee period.
The reason why analogue quartz watch is affected by magnetism
It is because the built-in motor of the watch which harnesses magnetic power,
and external strong magnetism, affect each other to stop the motor or to
suppress the turn of the motor.

Lumibrite
If your watch has Lumibrite
Lumibrite is a luminous paint that is completely harmless to human beings and
the natural environment; containing no noxious materials such as radioactive
substance. Lumibrite is a newly-developed luminous paint that absorbs light
energy of the sunlight and lighting apparatus in a short time and stores it to
emit light in the dark. For example, if exposed to a light of more than 500 lux
for approximately 10 minutes, Lumibrite can emit light for 3 to 5 hours.
Please note, however, Lumibrite emits the light it stores, the luminance level of
the light decreases gradually over time. The duration of the emitted light may
also differ slightly depending on such factors as the brightness of the place
where the watch is exposed to light and the distance from the light source to
the watch.
※In general, when you enter a dark place from a bright environment, your eye cannot
adapt to the change in light levels quickly. At rst, you can hardly see anything, but as
time passes, your vision gradually improves. (Dark adaptation of the human eye)

The battery life is the estimated life for a
watch with a new battery installed. The
battery in your watch at the time of purchase
was inserted in the watch at the factory for
performance checks. It may run down earlier
than the above-specied period.
○When the battery nears its end, the second
hand moves at two-second intervals
instead of normal one-second intervals. The
watch remains accurate while the second
hand is moving at two-second intervals.

■ SPECIFICATIONS • BATTERY (MOVEMENT)
■ INTERCALARY SECOND (LEAP SECOND)
Normally there are 86,400 seconds in a day. Due to a slight change in the
earth's rotation, an extra second may be added to one day during the year.
This is called the intercalary second. Every year the decision is made whether
such an adjustment is needed. When the adjustment takes place, the standard
time should be corrected by delaying the standard time one second. To keep
your SEIKO watch accurate with the world standard time, adjust your watch to
a time signal whenever such adjustment is made. According to the information
from the observatories all over the world, the standard time is delayed one
second simultaneously throughout the world by the Greenwich Royal
Observatory. In the Greenwich Mean Time, an extra second will be added to
the one minute between 11:59 p.m. and 0:00 a.m. either on December 31st
or on June 30th. However, the adjustment may not be made in some years.
Please check by a newspaper, etc. whether such an adjustment will be made
or not.
