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,
accuracy 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.
Contact the retailer from whom the watch was purchased.

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.

"HOW TO
USE"
Unscrew.
Screw up.
* 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 turning it
clockwise while pressing it.
• If the crown is too stiff to be screwed in, turn the crown counterclockwise once and
then give another try.
• Do not screw it in by force as it may damage the slots of the crown.

mainspring.
* Turning the crown counterclockwise (the
6 o’clock direction) does not wind the
mainspring.
2. C on tinue to tur n the c row n un til the
mainspring is sufficiently wound. The small
second hand will start moving.
3. Set the time and date before putting the
watch on your wrist.

English
HOW TO SET THE TIME AND DATE
• Check that the watch is operating, and then set the time and date.
• The watch is provided with a date function and is designed so 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.
English
* 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. However, when
the stopwatch is used continuously for a certain period, the watch may not operate
for as long as 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 8 hours a day. If the watch is used
without being worn on the wrist (if it is used on the desk like a clock, for example),
make 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 mainspring
torque (force) is low at the beginning of its winding due to the characteristics of
mechanical watches. The small 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.
1. Pull out the crown to the first click. (The
small second hand continues moving and
the accuracy of the watch is unimpaired.)
2. The date can be set by turning the crown
clockwise. 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
clockwise.
CAUTION
• Do not set the date between 8:00 p.m. and 2:00 a.m. If you do so, the date
may not change properly on the following day or malfunction of the watch
may occur.

English
●Date adjustment at the beginning of the month
It is necessary to adjust the date on the first day after a month that has less than
31 days.
English
3. Pull out the crown to the second click when the small second hand is at the 12
o’clock position. (The small 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.
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
normal position.
31
CAUTION
• The mechanism of mechanical watches is different from that of quartz
watches.
When setting the time, make sure to turn back the minute hand a little
behind the desired time and then advance it to the exact time.
10
CAUTION
• Do not set the date between 8:00 p.m. and 2:00 a.m. If you do so, the
date may not change properly on the following day or malfunction of the
watch may occur.

How to read the stopwatch minute hand
Stopwatch hour hand
0.5 hour index
When the stopwatch hour hand is pointing at a
position after a short index (0.5 hour index), 30
minutes should be added to the minutes that the
stopwatch minute hand is indicating. In the case
illustrated above, the measured time should be
read as "6 hours 50 minutes and 10 seconds."
the STOPWATCH second hand
gives the average speed per
hour.
Tachymeter scale: "90"
“90” (tachymeter scale figure) x 1 (km or mile)
= 90 km/h or mph
lTachymeter scale can be used only when the time required is less than 60 seconds.
Ex. 2: If the measuring distance is extended to 2 km or miles or shortened to 0.5 km or
miles and the STOPWATCH second hand indicates “90” on tachymeter scale:
"90" (tachymeter scale figure) x 2 (km or mile) = 180 km/h or mph
"90" (tachymeter scale figure) x 0.5 (km or mile) = 45 km/h or mph

Tachymeter scale indicated by
the STOPWATCH second hand
gives the average number of
jobs accomplished per hour.
Tachymeter scale: "180"
“180” (tachymeter scale figure) x 1 job
= 180 jobs/hour
Ex. 2: If 15 jobs are completed in 20 seconds:
"180" (tachymeter scale figure) x 15 jobs = 2700 jobs/hour

l The telemeter can provide a rough indication of the distance to the source of light and sound.
l The telemeter indicates the distance from your location to an object that emits
both light and sound. For example, it can indicate the distance to the place
where lightning struck by measuring the time elapsed after you see a flash of
lightning until you hear the sound.
l A flash of lightning reaches you almost immediately while the sound travels to
you at a speed of 0.33 km/second. The distance to the source of the light and
sound can be calculated on the basis of this difference.
l The telemeter scale is graduated so that the sound travels at a speed of 1 km in
3 seconds.*
English
TELEMETER
TO MEASURE THE HOURLY RATE OF OPERATION
*Under the condition of temperature of 20 °C(68 °F.)
CAUTION
The telemeter provides only a rough indication of the distance to the place
where lightning struck, and therefore, the indication cannot be used as the
guideline to avoid the danger of lightning. It should also be noted that the
speed of the sound differs depending on the temperature of the atmosphere
where it travels.

HOW TO READ THE POWER RESERVE
INDICATOR (CAL. 6S37 ONLY)
• The power reserve indicator lets you know the winding state of the mainspring.
• Before removing the watch from your wrist, observe the power reserve indicator
to check if the watch has enough power stored to keep running until the next
time you wear it. If necessary, wind the mainspring. (To prevent the watch from
stopping, wind the mainspring to store the excess power that will allow the watch
to run for extra time.)

●Remarks on the automatic mechanism of the mainspring
The mainspring of the watch becomes fully wound when it is worn for twelve
hours for three to five consecutive days. However, the winding state of the
mainspring may vary depending on actual use conditions, such as the number
of hours you wear the watch or the extent of your movement while wearing it. It
is recommended that you observe the power reserve indicator to check the level
of remaining power of your watch.
* In a case where you wear the watch for a short period of time each day, observe
the power reserve indicator to check the level of the remaining power. If
necessary, manually wind the mainspring.
TO PRESERVE THE QUALITY OF YOUR WATCH
CAUTION
English
* When the mainspring is fully wound, the crown can be turned further, or the
mainspring may wind without damaging the mainspring itself. The mainspring
of the watch employs a slipping mechanism, an automatic watch specific
mechanism, to prevent the mainspring from overwinding.
● 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.
20
21
English
● 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 irritation 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, immediately
stop wearing the watch and seek medical attention.
22
● 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.
5 bar
WR
● 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.
English
CAUTION
● 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
10/15/20
10 bar/15 bar/20 bar, respectively, and is suitable for wearing
bar WR
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.
* Before using a water resistant 5, 10, 15 or 20 bar watch in water, make sure
the crown is pushed in completely.
Do not operate the crown when the watch is wet or in water. If used in sea
water, rinse the watch in fresh water and dry it completely.
23
English
NOTE:
Pressure in bar is a test pressure and should not be considered as corresponding
to an actual diving depth since swimming movements tend to increase the
pressure at a given depth. Care should also be taken when diving with the
watch into water.
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.
24
LUMIBRITETM
LumiBrite is a luminous paint that is completely harmless to human beings and the natural
environment, containing no noxious materials such as radioactive substances.
LumiBrite is a newly-developed luminous paint that absorbs the light energy of sunlight or
artificial light 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 5 to 8 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.
When you make a dive in dark water, LumiBrite may not emit light unless it has absorbed and
stored light sufficiently.
Before diving, therefore, be sure to expose the watch to light under the conditions specified
above, so that it fully absorbs and stores light energy. Otherwise, use the watch together with
an underwater flashlight.
English
* When taking a shower while wearing a water resistant 5 bar watch, or taking
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 returns to
normal temperature.

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
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.
● When affected by strong external magnetism, a mechanical watch may loss/gain
time temporarily. The parts of the watch may become magnetized depending on
the extent of the effect. In such a case, consult the retailer from whom the watch
was purchased since the watch requires repair, including demagnetizing.
