NAMES OF THE PARTS
CHARACTERISTICS OF A MECHANICAL
WATCH
(self-winding type, automatic winding type)
●This mechanical watch operates using power obtained from a mainspring.
●If the watch is completely stopped, manually turn the crown approximately 20
times to wind up the mainspring to start the watch.
●While loss/gain of a quartz watch is indicated by a monthly or annual rate, ac-
curacy of a mechanical watch is normally indicated by a daily rate (loss/gain per
day).
● Normal usage accuracy of a mechanical watch varies according to conditions of
use (time period that the watch is worn on the wrist, temperature environment,
hand movement, and winding state of the mainspring).
● When the watch is affected by strong magnetism, it temporarily gains or loses
time. If the watch encounters a strong magnetic field, the parts of the watch may
be magnetized. In this case, repairs such as removal of magnetism are required.

HOW TO USE
This watch is an automatic watch equipped with a manual winding mechanism.
• When the watch is worn on the wrist, the motion of the wearer's arm winds the
mainspring of the watch.
• If your watch is completely stopped, it is recommended that you manually wind
the mainspring by turning the crown.
1. Slowly turn the crown clockwise (in the 12 o’
clock direction) to wind the mainspring.
* Turning the crown counterclockwise (the 6
o’clock direction) does not wind the main-
spring.
●How to manually wind the mainspring by turning the crown
●Check the type of the crown of your watch

"HOW TO
USE"
The crown
does not
turn.
Unscrew the crown by turning it
counterclockwise.
To set the watch
The crown of your watch is
*the screw lock type.
Unscrew.
Screw up.
2. Continue to turn the crown until the main-
spring is sufficiently wound. The second
hand will start moving.
3. Set the time and date before putting the
watch on your wrist.
* If your watch has a screw-lock crown, the crown will screw into the watch case
for added protection.
• After completing all settings of the watch, screw the crown in again by turn-
ing it clockwise while pressing it.
• If the crown turns out to be too stiff to be screwed in, turn the crown coun-
terclockwise once and then give another try.
• Do not screw it in by force as it may damage the slots of the crown.

• Check that the watch is operating, and then set the time and date.
• The watch is provided with a date function and is so designed that the date
changes once every 24 hours. The date changes around 12 o’clock midnight. If
AM/PM is not properly set, the date will change around 12 o’clock noon.
1. Pull out the crown to the first click. (The second hand continues moving and the
accuracy of the watch is unimpaired.)
2. The date can be set by turning the crown counterclock-
wise. Turn it until the previous day’s date appears.
Ex.) If today is the 6th of the month, first set the date to ”5”
by turning the crown counterclockwise.
6
HOW TO SET THE TIME AND DATE
* There is no need to turn the crown further when the mainspring is fully wound. But
the crown can be turned without damaging the watch mechanism.
* Once the watch is wound up fully, it operates for about 50 hours.
* If the watch is used without being wound up fully, gain or loss of the watch may
result. To avoid this, wear the watch for more than 10 hours a day. If the watch is
used without wearing on the wrist (if it is used on the desk like a clock, for exam-
ple), be sure to wind it up fully every day at a fixed time.
* If the watch has stopped with the mainspring unwound, winding the mainspring
with the crown will not start the watch immediately. This is because the main-
spring torque (force) is low at the beginning of its winding due to the characteristics
of mechanical watches. The second hand starts to move when a certain degree
of strong torque is reached after the mainspring has been wound up. However,
swinging the watch from side to side to forcibly turn the balance can start the
watch sooner.
CAUTION
• Do not set the date between 10:00 p.m. and 1:00 a.m. If you do, the date
may not change properly / it may cause a malfunction.

CAUTION
• The mechanism of mechanical watches is different from that of quartz
watches.
When setting the time, be sure to turn back the minute hand a little be-
hind the desired time and then advance it to the exact time.
3. Pull out the crown to the second click when the second hand is at the 12 o’clock
position. (The second hand stops on the spot.)
Turn the crown to advance the hands until the date changes to the next. The time
is now set for the a.m. period. Advance the hands to set the correct time.
4. Push the crown back in to the normal position in accordance with a time signal.
It is necessary to adjust the date on the first day after a month that has less than 31
days.
Ex.) To adust the date in the a.m. period on the first day of a month following a
30-day month.
1. The watch displays "31” instead of "1”. Pull out the crown to the first click.
2. Turn the crown to set the date to "1” and then push the crown back in to the nor-
mal position.
CAUTION
• Do not set the date between 10:00 p.m. and 1:00 a.m. If you do, the date
may not change properly / it may cause a malfunction.

CAUTION
●RASH AND ALLERGIC REACTION
•
Adjust the band to allow a little clearance around your wrist to ensure proper
airflow.
• Prolonged and/or repeated contact with the band may cause skin irrita-
tion or dermatitis for those susceptible.
• Possible causes of dermatitis
• Allergic reaction to metals or leathers
• Rust, contamination or perspiration accumulated on the watch case or
band.
• If you should develop any allergic symptoms or skin irritation, immedi-
ately stop wearing the watch and seek medical attention.
●WATER RESISTANCE
●Non-water resistance
If ”WATER RESISTANT” is not inscribed on the case back,
your watch is not water resistant, and care should be taken
not to get it wet as water may damage the movement. If the
watch becomes wet, we suggest that you have it checked
by the retailer from whom the watch was purchased or your
SERVICE CENTER.
TO PRESERVE THE QUALITY OF YOUR WATCH
CAUTION
●CARE OF YOUR WATCH
• The case and band touch the skin directly. Keep the case and band clean
at all times. This will help to extend the life of the watch and will reduce
the risk of skin irritations.
• When you take the watch off, wipe off moisture, sweat or soil with a soft
dry cloth as soon as possible. This will help to extend the life of the case,
band and gasket.
<Leather strap>
• Gently blot up the moisture using a soft dry cloth. Do not rub the leather,
as this may cause abrasions or discoloration.
<Metal bracelet>
• To keep the bracelet clean, use a soft toothbrush dipped in clean or soapy
water. Be careful not to get water on the case.

* When taking a shower while wearing a water resistant 5 bar watch, or tak-
ing a bath while wearing a water resistant 10, 15 or 20 bar watch, make
sure to observe the following:
• Do not operate the crown when the watch is wet with soapy water or
shampoo.
• If the watch is left in warm water, a slight time loss or gain may be
caused. This condition, however, will be corrected when the watch re-
turns to normal temperature.
PRECAUTIONS ON WEARING YOUR WATCH
• Exercise care when you hold an infant or small child while wearing the
watch on your wrist, as the infant or child may be injured or develop an
allergic reaction caused by direct contact with the watch.
• Avoid undue shocks such as dropping or scratching against hard surfaces
or playing active sports, which may cause temporary malfunctions.
• There is a possibility of injury caused by wearing the watch on your wrist
especially if you fall down or bump into other people or objects.
NOTE:
Pressure in bar is a test pressure and should not be considered as corre-
sponding to an actual diving depth since swimming movements tend to in-
crease the pressure at a given depth. Care should also be taken when diving
with the watch into water.
●Water resistance (3 bar)
If ”WATER RESISTANT” is inscribed on the case back, your
watch is designed and manufactured to withstand up to 3 bar,
such as accidental contact with splashes of water or rain, but it
is not designed for wearing while swimming or diving.
●Water resistance (5 bar)*
If ”WATER RESISTANT 5 BAR” is inscribed on the case back,
your watch is designed and manufactured to withstand up to 5
bar and is suitable for wearing while swimming, yachting and
taking a shower.
●Water resistance (10 bar/15 bar/20 bar)*
If ”WATER RESISTANT 10 BAR”, ”WATER RESISTANT 15 BAR”
or ”WATER RESISTANT 20 BAR” is inscribed on the case back,
your watch is designed and manufactured to withstand up to
10 bar/15 bar/20 bar, respectively, and is suitable for wearing
while taking a bath or shallow diving, but not for scuba diving.
We recommend that you wear a SEIKO Diver’s watch while
scuba diving.

ACCURACY OF MECHANICAL WATCHES
●The accuracy of mechanical watches is indicated by the daily rates of one week
or so.
●The accuracy of mechanical watches may not fall within the specified range of
time accuracy because of loss/gain changes due to the conditions of use, such as
the length of time during which the watch is worn on the wrist, arm movement,
whether the mainspring is wound up fully or not, etc.
●The key components in mechanical watches are made of metals which 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.
●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 it is fully wound and im-
mediately before it is unwound. As the mainspring unwinds, the force weakens.
Relatively steady accuracy can be obtained by wearing the watch on the wrist fre-
quently 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.
Problem
The watch gains/loses
temporarily.
The date change at 12
o’clock noon.
The power supplied by the
mainspring has been
consumed.
The watch is worn on your
wrist only for a short period
of time, or the amount of
arm movement is small.
The watch has been left in
extremely high or low
temperatures for a long time.
The watch was brought into
close contact with a
magnetic object.
You dropped the watch, hit it against
a hard surface or wore it while
playing active sports. The watch was
exposed to strong vibrations.
Normal accuracy will resume when the
watch returns to normal temperature.
Normal accuracy will resume when the watch is kept away from
close contact with the magnetic source. If this condition persists,
consult the retailer from whom the watch was purchased.
Normal accuracy will not resume.
Consult the retailer from whom the
watch was purchased.
Consult the retailer from whom the
watch was purchased.
Advance the hands by 12 hours.
Consult the retailer from whom the
watch was purchased.
AM/PM is not properly set.
Water got inside the watch
due to the deterioration of
the gasket, etc.
The watch has not been
overhauled for more than 3 years.
Possible causes
The watch stops
operating.
Even though you wear the
watch every day, it soon
stops operating.
The glass is blurred and
the blur persists for a
long time.
*For the solution of troubles other than listed above, contact the retailer from whom the watch was purchased.
Solutions
Turn the crown or swing the watch to wind it up. The
watch will start operating. If the watch does not start,
consult the retailer from whom the watch was purchased.
Wear the watch for an extended period of
time, or when taking off the watch, turn the
crown to wind the mainspring.
