WARNING
CAUTION
Do not use the watch in scuba diving
or saturation diving.
Do not turn or pull out the crown
when the watch is wet.
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 this watch. For diving,
use special watches for diving.
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
per f or mance o f the watch is deteriorated.
Immediately consult the retailer from whom the
watch was purchased or SEIKO CUSTMER SERVICE
CENTER .
Do not leave moisture, sweat and dirt
on the watch for a long time.
CAUTION
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 faucet onto the watch.
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.
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.

Characteristics of mechanical watches(manual winding model, automatic winding model)
Crown
・This is a mechanical watch that uses the mainspring as
its power source.
There are two types of crown, a normal crown and a
screw-lock type crown.
Please check the type of the crown of your watch.
・When starting to use a watch after it stops, turn the
crown approximately 20 times by hand to wind the mainspring.
・Accuracy of mechanical watch is indicated by a daily
rate(loss or gain per one day), while that of quartz
watch is indicated by a monthly or annual rate.
・Accuracy of mechanical watch may slightly vary depending on the various conditions of use(such as the length
of time during which the watch is worn on the wrist, temperature environment, arm movement, and winding state
of the mainspring).

automatically through normal wrist movement.
The watch can also be wound up by turning the crown. To do so,
unscrew the crown by turning it counterclockwise.
3 To start the watch after it stops completely, wind it up either by
turning the crown or swinging it from side to side until the second hand starts moving. Then, set the time and date before
putting the watch on the wrist.
To wind up the watch, unscrew the crown by turning it counterclockwise, and then, turn it clockwise slowly. The watch cannot
be wound by turning the crown counterclockwise.

35
Band
The band touches the skin directly and becomes dirty with
sweat or dust. Therefore,lack of care may accelerate deterioration of the band or cause skin irritation or stain on a sleeve
cuff. The watch requires a lot of attention for long usage.
■ Metallic band
36
・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 a
sleeve cuff 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 and then brush it off with a soft toothbrush.
(Protect the watch body from water splashes by wrapping it 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 with a dry cloth.
・Do not expose the watch to direct sunlight for a long
time.
・Please take care when wearing a watch with a lightcolored band, as dirt or stains are likely to show.
・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 water resistant).
■ Polyurethane band
・A polyurethane band is susceptible to discoloration from
light, and it may be deteriorated by solvent or atmospheric humidity.
37
Special clasps A
・Especially a translucent, white, or pale-colored band easily adsorbs other colors, resulting in color smears or discoloration.
・Wash off dirt in water and clean the band with a dry
cloth.
(Protect the watch body from water splashes by wrapping it in plastic wrap, etc.)
・When the band becomes less flexible, 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.

LUMIBRITE
If your watch has Lumibrite
Lumibrite is a 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 dier 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 coming from a place that is bright to a place that is dark, it takes human eyes some time to adapt to the darkness making it dicult to see objects initially.
(Dark adaptation)
※ Lumibrite is luminous paint that stores and emits light, which is harmless to human beings and the environment, containing no toxic materials such as radioactive substances.

cleaning (overrhaul) is recommended approximately once
every 2 to 3 years in order to maintain optimal performance
of the watch for a long time. 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 parts such as a 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.
・When your watch is inspected and adjusted by disassembly and cleaning (overhaul), the movement of your watch
may be replaced.

Accuracy of mechanical watches
●The accuracy of mechanical watches is indicated
by the "daily rate."
●The accuracy of mechanical watches may not fall
within the specified range of time accuracy because
loss/gain changes due to the position of the watch,
which is dependent on the conditions of use, such
as the length of time during which the watch is
worn on the wrist, arm movement, and whether the
mainspring is wound up fully or not, etc.
●The loss/gain of mechanical watches is not
measured by a daily rate, but by daily rates of one
week or so.
46
●Mainspring wound condition and accuracy
In order to improve accuracy, it is important to regularly
supply energy to the balance that controls the speed
of the gears. The driving force of the mainspring that
powers mechanical watches varies between when fully
wound and immediately before it is unwound. As the
mainspring unwinds, the force weakens.
Relatively steady accuracy can be obtained by wearing
the watch on the wrist frequently for the self-winding
type and winding up the mainspring fully everyday at a
fixed time to move it regularly for the wind-up mechanical
type.
●Accuracy variation according to temperature
・The parts that compose the accuracy of mechanical
watches are made of metals. It is well known
that metals expand or contract depending on
temperatures due to metal properties. This exerts an
effect on the accuracy of the watches. Mechanical
watches tend to lose time at high temperatures
while they tend to gain time at low temperatures.
