■REMARKS ON THE BATTERY
● Notes on the battery
(1) Battery life
When a new normal battery is installed, this watch operates for approximately 2 years.
(2)Monitor battery
The battery in your watch may run down in less than two years after the date of purchase, as it is a monitor battery which is
inserted at the factory to check the function and performance of the watch.
(3)Battery change
①For battery replacement, be sure to have the battery replaced with a new one at the retailer from whom the watch was
purchased, and request the battery for exclusive use with the SEIKO watches.
②If the old battery is left in the water for a long time, a malfunction may be caused due to battery leakage, etc. Have it
replaced with a new one as soon as possible.
③Battery replacement is charged even if it runs down within the guarantee period.
④Once the case back is opened for battery replacement or other purposes, the original water resistant quality designed for
the watch may deteriorate when it is closed. When you have the battery replaced with a new one, also request the water
resistance test pertaining to the water resistant quality of your wtach. If your watch has 10-bar or higher water resistant
quality, be sure to have such test performed on the watch every time the battery is replaced.
1. Do not remove the battery from the watch.
2. If it is necessary to take out the battery, keep it out
of the reach of children.
3. If the child swallows it, consult a doctor
immediately as it will adversely affect the health of
the child.
WARNING
1. Never short-circuit, tamper with or heat the battery, or
never expose it to fire as it may explode, generate and
intense heat or catch fire.
2. The battery in your watch is not rechargeable. Never
attempt to recharge it, as this may cause battery
leakage or damage to the battery.
3. If the watch is left in a temperature below 5℃ or above
35℃ for a long time, it may cause the battery life to be
shortened. Also, the liquid crystal panel may decrease in
contrast, and the electroluminescent light may illuminate
for a shorter period of time.
CAUTION
■NECESSARY PROCEDURE AFTER BATTERY CHAGE (RESETTING THE IC)

■NOTE ON THE REPLACEMENT PARTS
(1) SEIKO makes it a policy to usually keep a stock of spare parts for its watches for 7 years. In principle, your watch can be
reconditioned within this period if used normally. (Replacement parts are those which are essential to maintaining the func-
tional integrity of the watch.)
(2) The number of years that a watch is considered repairable may vary greatly depending on the condition under which it was
used, and normal accuracy may not be achieved in some cases. We recommend, therefore, that you consult the retailer
from whom the watch was purchased, when having them repair your watch.
(3) The case, dial, hands, glass, bracelet, or parts thereof may be replaced with substitutes if the originals are not available.
■VIVIDIGI
"VIVIDIGI" is a newly developed liquid crystal panel that has various color combinations of segments and background
and lights up in various manners, providing wide varieties of displays.
Features
(1) "VIVDIGI" has high light-transmissivity and lightreflectance to give a vivid and clear display.
(2) The segments for digits and the entire background of the display can be illuminated in various colors.
(3) Either the whole display or only the segments are illuminated depending on models.
※Above features of "VIVIDIGI" are embodied differently from model to model.
■NOTE ON THE LIQUID CRYSTAL PANEL
The normal life expectancy for the liquid crystal panel of the watch is approximately 5 years. After that, it may decrease
in contrast, becoming difficult to read. Please contact the retailer from whom the watch was purchased to have the liq-
uid crystal panel replaced with a new one.
It will be made at cost.
●PRECAUTIONS ON WEARING YOUR WATCH
Take utmost care in the following cases:
・When clasping and unclasping the band, you may damage your nail, depending on the type of clasp used with the band.
・In case you tumble and fall or bump into others with the watch worn on your wrist, you may be injured by the reason of the
fact that you wear the watch.
・When you make contact with children, especially with infants, they may get injured or develop a rush caused by allergy.
・If your watch has a light-colored urethane or leather band, special care should be taken to keep it clean, as such bands easily
get soiled or discolored. Also, take utmost care not to bring the band into close contact with clothes or bags made of denim
and other materials whose color easily come off. The dye may stick to the band to make indelible stains.
●PERIODIC CHECK
・We suggest that you have your watch checked by watch dealer every 2 or 3 years or when the battery is replaced for oil con-
dition, battery electrolyte leakage or damage due to water or sweat. After checking the watch, adjustment and repair may be
required.
・When the replacing the parts or battery, please specify
GENUINE PARTS" . If an old battery is kept in the watch for a long
time, electrolyte leakage from the battery may damage the module.
・Be sure to have the gasket and push-pin replaced with new ones by a watch dealer when checking the watch or the battery is
replaced.
・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.
CAUTION
■ TO PRESERVE THE QUALITY OF YOUR WATCH
●WATER RESISTANCE
・Check the dial or case back of your
watch for the water resistant quality,
and then see the table below.
・Do not turn or pull out the crown when
the watch is wet, as water may get
inside the watch.
CAUTION
・If your watch is 3 bar water resistant, do not use it in water.
・If your watch is 5 bar water resistant, do not use it in any type of diving including skin diving.
・If your watch is 10 or 20 bar water resistant, do not use it in saturation diving or scuba diving.

●CARE OF YOUR WATCH
・The case and bracelet touch the skin directly just as underwear. If they are left dirty, the edge of a sleeve may be stained
with rust of those who have a delicate skin may have a rash.
・After removing the watch from your wrist, wipe perspiration or moisture with a soft cloth. This will prevent the watch from
being soiled, adding to the life of the gasket.
METAL BRACELET
・Clean the watch bracelet with a soft toothbrush dipped in water or soapy water. If your watch is not water-resistant, be
careful not to get the case wet when cleaning.
LEATHER BAND
・When removing moisture from a leather band, do not rub the band with the cloth as this may discolor it or reduce its gloss.
Be sure to blot up the moisture using a soft dry cloth.
SOFT PLASTIC BRACELET
・If your watch has a soft plastic band such as urethane band, do not leave the watch under a fluorescent lamp or direct
sunlight for a long time, or do not leave the band soiled. Otherwise, the band may be discolored, hardened or broken. Also,
do not keep the watch in a place where it is exposed to high humidity, or do not leave the band wet with perspiration or
water. Otherwise, the band may be discolored in a very short time.
When the band is soiled, rinse it in soapy water. Do not use solvents for cleaning as some solvents may deteriorate the
band.
If your watch has a semitransparent urethane band, which is easily discolored, special care should be taken to keep it
clean. Depending on the condition of use, the semitransparent band may be discolored after several months of use.
●If your watch is not water-resistant, be careful not to get wet with water or sweat. When it gets wet with water or sweat,
wipe it thoroughly dry with a hygroscopic cloth.
●If your watch is 5, 10 or 20 bar water resistant, rinse it in a bowl of fresh water after used in seawater. Do not use chemicals
to wash it.
●If your watch has a rotating bezel, clean the bezel regularly. Otherwise, dust will gather under it, making the rotation harder.
CAUTION
※If button A is pressed while both the hour and minute digits (12/24-hour indication) are flashing, the display will
return to the Time display. In case you would like to adjust any digits, press button A for 1 to 2 seconds to show
the Time/Calendar setting display again.

●ABOUT BATHING
Your watch can be worm while bathing if it is equipped with water resistance over 10 bar.
・In that case, please note the following carefully.
・Please do not operate your watch (Crown operation, Button operation etc.) When it is wet with soap or shampoo. it sometimes
causes a reduction in the water proofing.
・When the watch gets warm due to warm water, the watch could gain or lose time to some degree. However, the watch will
return to its usual accuracy at normal temperatures.
