●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.
●PRECAUTIONS ON WEARING YOUR WATCH
Take utmost care in the following cases:
・When clasping and unclasping the band, you may dam-
age 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.
●CARE OF YOUR WATCH
・The case and bracelet touch the skin directly just as underware. 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.
<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.
<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.
<SOFT PLASTIC BRACELET>
・The bracelet made of soft plastics does not require special care. If it gets
dirty, however, it may cause trouble to the skin. Rinse it with soapy water
from time to time. Since it is a chemical product, it may deteriorate by the
■TO PRESERVE THE QUALITY OF YOUR WATCH
CAUTION
●RASH AND ALLERGY
・Adjust the bracelet or band so that there will be a little clearance between
the bracelet or band and your wrist to avoid accumulation of perspiration.
・If you are constitutionally predisposed to rash, the band may cause you to
develop a rash or an itch depending on your physical condition.
・The possible causes of the rash are as follows:
1.Allergy to metals or leathers
2.Rust, dust or perspiration on the watch or band
・If you develop any skin reactions, take off the watch and consult a doctor
immediately.
use of solvents. The band will become hardened or discolored after
several years of use. In that case, replace it with a new one.
・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
■SPECIFICATIONS■REMARKS ON AFTER-SALES SERVICING
・If the watch requires service, take it to the retailer from whom
the watch was purchased. If the trouble occurs within the
guarantee period, submit the certificate of guarantee together
with the watch.
・For repair after the guarantee period or for any other
information regarding the watch, contact the retailer from whom
the watch was purchased, the "CUSTOMER SERVICE
DEPARTMENT" of SEIKO WATCH CORPORATION.
・Guarantee coverage is spelled out in the certificate of
guarantee. Please read it carefully and keep the certificate for
ready reference.
■REMARKS ON REPLACEMENT PARTS
・ SEIKO makes it 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 functional integrity of the watch.)
・ The number of years that a watch is considered repairable
may vary greatly depending on the conditions 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.
・ The case, dial, hands glass and bracelet, or parts thereof
may be replaced with substitutes if the originals are not
available.

■HOW TO USE
●PLACES TO KEEP YOUR WATCH
・If the watch is left in a temperature below
5℃
or above 35℃ for a long time it may
function improperly or stop operating.
・Do not leave the watch in a place where it is subjected to strong magnetism or
static electricity.
・Do not leave the watch where there is strong vibration.
・Do not leave the watch in a dusty place.
・Do not expose the watch to gases or chemicals.
(Ex.: Organic solvents such as benzine and thinner, gasoline, nail polish, cosmetic
spray, detergent, adhesives, mercury, and iodine antiseptic solution.)
・Do not leave the watch in a hot spring, or do not keep it in a drawer having
insecticides inside.
●PERIODIC CHECK
Periodic inspection and adjustment by disassembly and cleaning (overhaul) is recom-
mended approximately once every 2 to 3 years in order to maintain optimal perfor-
mance of the watch for a long time. The power transmission gear of the movement of
this watch constantly receives force. To ensure that this mechanism works properly all
the time, washing parts, changing oil, adjusting accuracy, checking functions and
replacing consumable parts on a regular basis are important. The first overhaul after
the purchase of your watch is particularly important for preserving long-time use of
your watch. According to use conditions, the oil retaining condition of your watch
mechanical parts may deteriorate, abrasion of the parts due to contamination of oil
may advance or delay the time significantly, or the watch itself may stop. As the parts
such as gasket may deteriorate, water-resistant performance may be impaired due to
intrusion of perspiration and moisture. Please contact the retailer from whom the
watch was purchased for inspection and adjustment by disassembly and cleaning
(overhaul). For replacement of parts, please specify “SEIKO GENUINE PARTS.”
When asking for inspection and adjustment by disassembly and cleaning (overhaul),
make sure that the gasket and push pin are also replaced with new ones.

[IF YOUR WATCH HAS LUMIBRITE]
LumiBrite is a luminous paint that is completely harmless to human beings and natural environment, containing no
noxious materials such as radioactive substance.
LumiBrite is a newly-developed luminous paint that absorbs the 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, that, as 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.
<Reference data on the luminance>
(1) Sunlight
[Fine weather]: 100,000 lux [Cloudy weather]: 10,000 lux
(2) Indoor (Window-side during daytime)
[Fine weather]: more than 3,000 lux [Cloudy weather]: 1,000 to 3,000 lux [Rainy weather]: less than 1,000 lux
(3) Lighting apparatus (40-watt daylight fluorescent light)
[Distance to the watch: 1 m]: 1,000 lux [Distance to the watch: 3 m]: 500 lux (average room luminance)
[Distance to the watch: 4 m]: 250 lux
■NOTE ON LUMIBRITE
1.Pull out the crown to the second click.
If the crown is of the screw lock-type, unscrew the crown by turning it
counterclockwise, and then, pull it out to the second click.
*The second hand will not stop by pulling out the crown to the second click.
2.Turn the crown to set the current time.
*When setting the time, be sure to check that AM/PM is set properly.
(The watch is so designed that the date changes once every 24 hours.)
*The mechanism of a mechanical watch is different from that of a quartz
watch. First, set the hands to the time a few minutes behind the correct time,
and then, advance them to the exact time.
3.Push the crown back in to the normal position.
If the crown is of the screw lock type, screw it in completely by turning
it clockwise while pressing it.
*The telephone time signal service (TEL 117) is helpful in setting the hands
accurately.
