■■INTRODUCTION -About mechanical watch-
Quartz watches and mechanical watches - what is the difference?
Thank you very much for purchasing the Grand Seiko mechanical watch.
Take hold of your watch softly.
Hear the watch ticking,
tick tock, tick tock, tick tock,
soft and faint, a dignified sound can be heard.
The sound can be called
the crystal of the craftsmen's spirit and skill.
Handpicked parts assembled one by one,
Quartz watches that you have come to be
familiar with.
These are just like airplanes, controlled by
computers.
A battery, IC, and crystal make quartz
watches work accurately, electrically.
Some loss or gain may occur while the
watch is worn.
However, this will be too small to notice in
your daily life.
If a quartz watch resembles an airplane,
a mechanical watch is like a bicycle.
All watch parts work together mechanically
to make it tick.
Thus, a mechanical watch is easily affected
by the outside environment.
English
We will explain by example
If it is hot, the watch tends to lose time.
When power driving the watch becomes
short (when the amount the spring is
wound is short), accuracy becomes
unstable.
If the resting position of the watch is
changed, accuracy is also affected.
The rate of loss/gain could be significant
that you will notice in your daily life.
carefully, with craftsmanship,
giving life to a mechanical watch.
This is proven by the sound.
Talking about accuracy,
mechanical watches cannot be compared to
quartz watches, that is for certain.
However, the accuracy of a mechanical watch
is pursued by human hands.
The accuracy is shown by the daily rate
Full of spirit and know-how of craftsmen.
A mechanical watch - complicated, sensitive,
and having a human touch.
We would like to let all of you know
The measured loss/gain of the watch per day
This is called the daily rate.
The accuracy of a mechanical watch
is usually shown in this daily rate.
Wishing you will have a nice time
The accuracy of a mechanical watch changes
delicately day by day,
depending on the condition in which the watch is used
or the outside environment.
with your Grand Seiko for a long, long time.
Thus,
the charm of a mechanical watch, which has no bounds.
So we made this handbook, mainly detailing the accuracy.
By only observing loss/gain in one day,
you cannot judge how accurate the watch works.
If you check the average of the daily loss/gain rate,
you can judge the accuracy of the watch.
In the case of quartz watches, the accuracy is usually
shown by the monthly/yearly rate.
Total losses/gains for a month/year are called the loss/
gain rate of quartz watches.
2
Characteristics of a mechanical watch
3
Mean daily rate / Normal usage accuracy
Thus to show the accuracy of a mechanical watch evenly, not depending on the environment,
loss/gain of a mechanical watch is measured
before the inside movements of the watch are put in the case,
under controlled conditions,
with many days of tests.
And the measured rate is called "mean daily rate".
This rate is the data measured in an environment that is artificially controlled,
in order to fairly evaluate/show the abilities of mechanical watches without being
influenced by environmental changes.
So it is different from “normal usage accuracy”
when you are actually wearing the watch.
The accuracy of a mechanical watch varies delicately day by day, depending on the
environment.
This is like a living thing,
one of the charms that a mechanical watch has.
Normal usage accuracy should be from –1 second/day to +10 seconds (–1 to +8 seconds for Cal. 9S86
and 9S85, –5 to +10 seconds for Cal. 9S27) /day. If the average of the daily rates exceeds this level, we
would like the responsibility for adjusting it accordingly (The cost of adjusting the watch is free of charge
for three years from the date of purchase.)
To adjust the accuracy as accurately as possible, information such as the rate of loss/gain of your watch
and how you use it, are very important. Please let us know the following when you ask for adjustment of
your watch by our service center.
(1) The average daily loss/gain rates for one week to ten days
Ex. an average of +11 seconds
(2) Approximate hours of wearing the watch in one day in the above period
Ex. Approximately 10 hours
(3) The resting position of the watch while you don't wear it
Ex. Horizontal - Dial up
Vertical - the crown up
4
Characteristics of a mechanical watch
As there are rules for everything,
there is a rule for winding the spring.
If your watch is a wind-up mechanical type,
turn the crown every day, at a fixed time
to wind the mainspring sufficiently.
You have not heard this before?
Please keep it in mind.
The mainspring - the source of energy for a
mechanical watch
When it is fully wound, it can supply the most stable
energy to every part of the watch movement, and the
accuracy of the watch becomes most stable.
Power the mainspring supplies
In both the ISO3159 and Grand Seiko Standard,
the standard rate is mean daily rate.
⇒ “THE GRAND SEIKO STANDARD” page 34
Wind the mainspring of your mechanical watch at a fixed time.
High
Low
English
The accuracy of a mechanical watch varies depending on many things,
such as the amount the spring is wound by movements of your arm, temperature, or resting position
of the watch.
For lifelong use of your mechanical watch rule No.1
To use the watch with better accuracy,
wind the mainspring every day, at a fixed
time.
Please keep to this rule as best as possible.
For instance,
You may make it a rule to wind the spring
When you wake up, or at lunchtime.
Duration from a fully wound state
Even if your watch is a self-winding type,
when you feel the accuracy is not stable,
shake the watch or turn the crown to
wind the mainspring further.
If you work at a desk, etc., and do not
move too much,
the spring will not be wound sufficiently.
For lifelong use of your mechanical watch rule No.2
Place your watch correctly, like this.
Horizontaldial up
Half of one day, twenty-four hours,
when you do not wear your watch.
The accuracy while you do not wear the watch is included in “normal
usage accuracy”.
The mechanical watch that you take off
Which position should the watch be put in?
Vertical-3
o’clock
The loss/gain of a mechanical watch
depends on the resting position of the watch.
In one position, the watch tends to gain, in another position, it doesn't.
For instance, while you are sleeping at night,
when you do not wear your watch,
put the watch in various positions for seven to eight hours, such as
placing it with its face turned up, or with the crown up,
to find the best resting position for the watch for reducing the loss/
gain that occurs while you are wearing your watch.
For lifelong use of your mechanical watch

For lifelong use of your mechanical watch rule No.3
For lifelong use of your mechanical watch rule No.5
Do not give your mechanical watch a strong shock.
A piece of metal of about 0.1 mm, as
thin as a hair, is wound.
That is the key that controls the
accuracy of all mechanical watches.
When you play golf, tennis or
baseball.
<<Balance>>
Balance spring
In other words,
When it is hot, the balance spring
expands and the watch tends to lose.
When it is cold, the balance spring
contracts and the watch tends to gain.
This is typical.
For instance,
at the moment you hit a golf ball with a club,
the impact of the ball against the club is about 1 ton.
When you play a sport that gives
your arm a strong impact.
Please take off your mechanical
watch.
The impact is given to your wrist,
and this will affect very small parts inside your
mechanical watch.
There are reasons for this.
Sometimes, the impact will deform or break a watch
part.
“Good shot” for you becomes “bad shock” for your
watch.
Metals expand and contract depending on the
temperature.
This characteristic of all metals also applies to the
balance spring.
This affects the accuracy of a mechanical watch.
For lifelong use of your mechanical watch rule No.4
Keep your mechanical watch away from magnetic objects.
6
For lifelong use of your mechanical watch rule No.6
After you take off your watch,
do you leave it by your cell phone?
Or put it on a television or next to your PC?
Do you put it in your bag with your cell phone?
Overhaul, once every three years
Watches do not like magnetism.
They may lose or gain when affected by
magnetism.
In the case of a mechanical watch, there is no
need to change your battery.
However,
maintenance of your watch is also necessary.
To make your mechanical watch work more
accurately,
it is important not to leave the watch close to
magnetic objects for a long time.
Once every three years,
please take your watch to our service center
for examining and cleaning every part of your
watch.
In particular, cell phones, televisions and
speakers of PCs have strong magnetism.
A magnetic necklace, a clasp of a handbag,
magnetic parts of refrigerators,
there are many magnetic objects around us
Please be careful.
Once you start using it,
your watch never takes a rest.
For lifelong use of your mechanical watch
English
Accuracy will vary depending on the temperature.
Love your watch, once every three years.
Talk about an overhaul.
Especially,
the first three years after you start using your watch is the
period when
each part gets used to one another,
and contacting each other causes additional metal powder.
The first overhaul is
the key to the life of your mechanical watch.
Please keep in mind
an overhaul, once every three years
can be considered
love for your watch.
And in the case of a mechanical watch, power
given to its gear is stronger,
compared to a quartz watch.
So parts may wear,
oil may dry or be insufficient in some parts.

■■CAUTIONS FOR ACCURACY
■■HANDLING CAUTIONS
WARNING
To indicate the risks of light injuries or material damages unless
the following safety regulations are strictly observed.
Avoid wearing or storing the watch in the following places.
laces where volatile agents (cosmetics such as polish remover, bug
○P
repellent, thinners etc.) are vaporizing
laces where the temperature drops below 5 ºC or rises above 35 ºC for a long time
○P
○ Places of high humidity ○ Places affected by strong magnetism or static electricity
○ Dusty places
○ Places affected by strong vibrations
English
○N
ormal usage accuracy of a mechanical watch varies depending on individual customer’s
use conditions such as winding state of the mainspring by movement amount of the
customer’s arm per day, temperature environment, and position (orientation of a watch).
Accordingly, the actual normal usage accuracy when the watch is used by a customer
may differ from the numerical value of each item specified in the Grand Seiko Standard.
○ The target range of normal usage accuracy when the watch is actually used by
a customer is set to –1 to +10 seconds (–1 to +8 seconds for Cal. 9S86 and
9S85, –5 to +10 seconds for Cal. 9S27) per day.
To correctly judge the normal usage accuracy, please use the watch for not only one day,
but also approximately one week to 10 days under normal use conditions to check loss
or gain of time. If the average value per day exceeds the target range, we will adjust the
watch. (Adjustment is provided Free of charge for three years after purchase, then
charged thereafter. For more details, please refer to the instruction manual.)
○ The enclosed Grand Seiko Standard Inspection Certificate certifies the values of a
movement single unit before assembly in a case which are measured under an artificially
controlled environment in the production factory passed the Grand Seiko Standard
Inspection.

○T
his watch is an automatic winding type (with manual winding function).
○ T he mainspring can be sufficiently wound automatically by natural
movement of the arm while normally worn on the wrist. In addition, it can
be wound by turning the crown.
○ A stopped watch can be started by arm movement when it is worn on the
wrist, however, before wearing the watch, wind the mainspring sufficiently
and set the time and date. When winding the mainspring, turn the crown at
the normal position clockwise (12 o'clock direction) slowly. If you turn the
crown counterclockwise (6 o'clock direction), it will turn free. The
mainspring is sufficiently wound when the crown is turned approximately 45
times (60 times for Cal. 9S68 and 9S65, 30 times for Cal. 9S27). When the
mainspring is in the full-winding state, it is designed so that the mainspring
slips if it is overwound. Therefore, it is not necessary to worry about
breaking the mainspring, however, please refrain from excessive operation.
※ It is recommended that you wear the watch on your wrist more than 10 hours a day
to keep the mainspring wound up. If the mainspring is not wound up sufficiently, the
watch may lose or gain time. If you do not wear the watch on your wrist, wind the
mainspring up sufficiently by turning the crown by hand every day at a fixed time.

and set the time and date. When winding the mainspring, turn the crown at
the normal position clockwise (12 o'clock direction) slowly. If you turn the
crown counterclockwise (6 o'clock direction), it will turn free. The mainspring
is sufficiently wound when the crown is turned approximately 45 times (60
times for Cal. 9S66). When the mainspring is in the full-winding state, it is
designed so that the mainspring slips if it is overwound. Therefore, it is not
necessary to worry about breaking the mainspring, however, please refrain
from excessive operation.
※ It is recommended that you wear the watch on your wrist more than 10 hours a day
to keep the mainspring wound up. If the mainspring is not wound up sufficiently, the
watch may lose or gain time. If you do not wear the watch on your wrist, wind the
mainspring up sufficiently by turning the crown by hand every day at a fixed time.

○ From the state of the mainspring being sufficiently wound, it continuously
operates for approximately 72 hours or more.
○ If the mainspring is not wound up sufficiently, the watch may lose or gain time.
To attain a high accuracy, we suggest that the mainspring is wound up fully
once a day at a fixed time.
hen the watch is used from a state in which the mainspring is unwound to a stop, it
※W
does not move immediately even if the mainspring is wound with the winding crown.
This is because of the mechanical watch's feature that the mainspring torque (force) is
weak at the beginning of mainspring winding. The seconds hand starts moving when
the mainspring is wound to reach a certain degree of torque strength, while the watch
can be made to move advance by shaking it to rotate the balance wheel forcibly.
Do not pull out the crown.

How to wind the mainspring
Generally speaking, the crown of the manual winding mechanical watch cannot be turned
further when it is wound up fully. However, the crown of the Cal. 9S64 and 9S63 can be
turned endlessly even after the watch is fully wound up. If you keep turning the crown, that
gives no effect to winding, but the watch is so designed as to make the winding a little
tighter and not to damage the watch. However, please refrain from excessive operation.

OF DIVER’S MODEL
By using the rotating bezel, you can measure the
elapsed time since the start of an event or an activity
such as diving.
This watch has a unidirectional rotating bezel. As the evaluation of the remaining
air in your cylinder is based on the information of the elapsed time of the dive, the
rotating bezels for a diver’s watch is designed to rotate only counterclockwise, so
that the watch is prevented from displaying the elapsed time shorter than it actually
is.
CAUTION
Make sure that you check the correct remaining
amount of air in your cylinder before diving. Use the
display of the elapsed time by the rotating bezel only
as a guide during diving.
How to use the rotating bezel

Your Grand Seiko watch is built to the very highest standards to
ensure that it keeps time as accurately as possible. In this section,
we define the Grand Seiko Standard, what it means and how your
watch is tested against it.
The “Grand Seiko Standard” is our own accuracy standard. Your
watch has been tested individually and has met this standard. All
Grand Seiko calibers are tested in the same way and for the same
period but there are two standards, one for Grand Seiko men’s
watches and another for Caliber 9S27 which is used in Grand
Seiko’s women’s watches. This is because the smaller size of
Caliber 9S27 results in a different level of precision.
The movement in your Grand Seiko watch has been tested in our
facilities for a period of 17 days, in six different positions and at three
different temperatures. It has achieved or surpassed the standards
of accuracy shown on page 35, with the accuracy being defined
as a gain or loss per day (the “mean daily rate”).

Cautions for accuracy of mechanical watch
① Accuracy of mechanical watch is "mean daily rate."
Accuracy of the quartz watch is indicated monthly or annually such as a monthly
rate of ±15 seconds or annual rate of ±10 seconds. This indicates the degree of
total difference in accuracy when the quartz watch is continuously used for a
month or a year. To the contrary, accuracy of the mechanical watch is normally
indicated as a "mean daily rate." Accuracy of the mechanical watch slightly
varies each day as it is influenced by various conditions of use, and it is normally
unstable. Then it is required to judge whether the accuracy is satisfactory or not
by checking the mean values in the case of use for a week to ten days, but not
for only one day. For normal usage accuracy of Grand Seiko mechanical watch,
-1 to +10 seconds (+8 seconds for Cal. 9S86 and 9S85, –5 to +10 seconds for
Cal. 9S27) per day are specified as target values. If the mean value exceeds the
abovementioned target value in the normal usage condition when the watch is
used for a week to ten days, we will adjust it.
*Adjustment is provided free of charge within three years after purchase. After the
three-year period, adjustments are charged. However, please note that the parts that
are age-deteriorated due to long duration of use may not be adjusted to your desired
accuracy. ⇒For details, refer to pages 34 and 39.
② Factor influencing accuracy -1: Wound amount of the mainspring
In order to use the mechanical watch at better accuracies, it is required to supply a
constant strong energy wherever possible to respective parts. In the state where the
mainspring is fully wound, accuracy is stable, however, when the mainspring is unwound
to weaken energy to be supplied, the parts controlling accuracy tends to be externally
influenced, and accuracy becomes unstable. In order to use a mechanical watch at a
steady accuracy, it is recommended to use it in a condition where the mainspring is
sufficiently wound.
③ Factor influencing accuracy -2: Temperature influence
Mechanical watch parts are metal which slightly elongate and contract by
change in temperature, and this influences accuracy. Normally, under high
temperatures, it tends to lose time, and under low temperatures, it tends to
gain time.
④ Factor influencing accuracy -3: Difference by position (orientation of a watch)
Parts related to accuracy of a mechanical watch are also influenced by the
earth's gravity. For example, gain or loss differs when a watch is horizontally
placed and when it is vertically placed in the 12 o'clock up position. When the
watch is not worn on the wrist, accuracy errors that occur while wearing can
also be compensated to some extent according to the position. Try to place it
in various positions to find the position appropriate to your watch.

English
Mechanical watches have a mechanism that is moved by power generated
when the mainspring is unwound, and small metal parts physically work
together to control the accuracy. Fragile metal parts of a mechanical watch are
easily influenced by external environment such as temperature, gravity, and
shock. Also, conditions of use such as normal usage time and winding state of
the mainspring can, influence the gain/loss of the watch.

Possible Causes
Lumibrite is a luminous paint that is completely harmless to human
beings and the natural environment; containing no noxious materials
such as radioactive substance. Lumibrite is a newly-developed
luminous paint that absorbs 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, 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.
