Length adjustment service for metallic bands is available at the retailer from whom the watch
was purchased. If you cannot have your watch repaired by the retailer from whom the watch
was purchased because you received the watch as a gift, or you moved to a distant place,
please contact SEIKO CUSTOMER SERVICE CENTER. The service may also be available on a
chargeable basis at other retailers, however, some retailers may not undertake the service.

If your watch has a protective lm for preventing scratches, make sure to peel it off

before using the watch. If the watch is used with the lm on it, dirt, sweat, dust, or

moisture may be attached to the lm and may cause rust.

English

Immediately stop wearing the watch in the following cases.

○

If the watch body or band becomes edged by corrosion etc.

○

If the pins protrude from the band.

※

Immediately consult the retailer from whom the watch was purchased or

SEIKO CUSTOMER SERVICE CENTER.

Keep the watch and accessories out of the reach of
babies and children.

Care should be taken to prevent a baby or a child accidentally swallowing the
accessories. If a baby or child swallows the battery or accessories, immediately
consult a doctor, as it will be harmful to the health of the baby or child.

○

Normal 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 posture (direction of the watch).
Accordingly, the actual normal usage accuracy when the watch is used by a customer

may differ from the numerical value of each item specied 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 (in the case of Cal. 9S86 and 9S85, -1 to +8
seconds) 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 two 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 articially

controlled environment in the production factory passed the Grand Seiko standard
inspection.

Should the certicate be lost or after repair or adjustment, it cannot be reissued.

Avoid wearing or storing the watch in the following places.

○

Places where volatile agents (cosmetics such as polish remover, bug repellent,
thinners etc.) are vaporizing

○

Places where the temperature drops below 5 ºC or rises above 35 ºC for a long time

○

Places of high humidity

○ Places affected by strong magnetism or static electricity

○

Dusty places

○

Places affected by strong vibrations

If you observe any allergic symptoms or skin irritation

Stop wearing the watch immediately and consult a specialist such as a dermatologist or an allergist.

Other cautions

○

Replacement of the metal band requires professional knowledge and skill. Please ask the retailer
from whom the watch was purchased for replacement of the metal band, as there is a risk of hand

or nger injury and fear of losing parts.

○

Do not disassemble or tamper with the watch.

○

K

eep the watch out of the reach of babies and children. Extra care should be taken to avoid risks

of any injury or allergic rash or itching that may be caused when they touch the watch.

○

If your watch is of the fob or pendant type, the strap or chain attached to the watch may damage
your clothes, or injure the hand, neck, or other parts of your body.

○

Please keep in mind that if a watch is taken off and placed down as it is, the case back, the band and
the clasp will rub against each other possibly causing scratches on the case back. We recommend
placing a soft cloth between the case back, the band and the clasp after taking off your watch.

WARNING

Do not use the watch in scuba diving or
saturation diving.

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 the water-resistant watch with the BAR
(barometric pressure) display. For diving, use special watches for diving.

CAUTIONS

To indicate the risks of light injuries or material damages unless
the following safety regulations are strictly observed.

■CAUTIONS FOR ACCURACY

■HANDLING CAUTIONS

To indicate the risks of serious consequences such as severe injuries
unless the following safety regulations are strictly observed.

WARNING

Do not leave moisture, sweat and dirt on the
watch for a long time.

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 the faucet.

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.

CAUTIONS

Do not turn or pull out the crown when the
watch is wet.

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 performance of the watch is deteriorated. Immediately consult the retailer
from whom the watch was purchased or SEIKO CUSTMER SERVICE CENTER.

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.

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 dignied sound can be heard

The sound can be called

The crystal of the craftsmen's spirit and skill

Handpicked parts assembled one by one

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

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 charm of a mechanical watch, which has no bounds

So we made this handbook, mainly detailing the accuracy

Wishing you will have a nice time

With your Grand Seiko for a long, long time

We will explain by example

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

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

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

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

Thus,

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

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

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 "the accuracy of mechanical watch movement at rest"

In both the Ofcial Swiss Chronometer Inspectorate and Grand Seiko Standard

The standard rate is the accuracy of mechanical watch movement at rest

＊

Refer to the instruction manual for further information on the Grand Seiko Standard and Rating

Certicate.

The accuracy of a mechanical watch in use should be from –1 second/day to +10 seconds (+8 seconds
for Cal. 9S86 and 9S85) /day. If the average of the daily rates exceeds this level, we would like the
responsibility for adjusting it accordingly ([Only in Japan]. The cost of adjusting the watch is free of charge
for two 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

This rate is the data measured in an environment that is articially controlled

In order to fairly evaluate/show the abilities of mechanical watches without being

inuenced by environmental changes

So it is different from “the accuracy of mechanical watches in use”
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

As there a re rules for everything
There i s a rule for winding the sp ring

You have not heard this before?
Please keep it in min d

The mainsp ring - the sourc e of energy for a
mechanical watch
When it is fully wound, it ca n supply the most sta ble
energ y to every part of the watch movement, and the
accuracy of the watch be comes most stable

Even if your watch is a self-winding type,
when you feel the accuracy is not stable,
Shake the watch or turn the crown about
thirty times to wind the mainspring further
If you work at a desk, etc., and do not
move too much,

The spring will not be wound sufciently

If your watch is a wind-up mechanical type,
Turn the crown thirty to forty times every day,

at a xed time
To wind the mainspring sufciently

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

Wind the mainspring of your mechanical watch at a xed time.

Place your watch correctly, like this.

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 “the
accuracy of a mechanical watch in use”

The mechanical watch that you take off
Which position should the watch be put in?

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 nd the best resting position for the watch for reducing the loss/

gain tha t occurs while you are wearing your watch

The accuracy of a mechanical watch movement at
rest / the accuracy of a mechanical watch in use

Characteristics of a mechanical watch

<<Balance>>

Hairspring

8

9

English

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

Metals expand and contract depending on the
temperature
This characteristic of all metals also applies to the
hairspring
This affects the accuracy of a mechanical watch

In other words,
When it is hot, the hairspring expands
and the watch tends to lose
When it is cold, the hairspring
contracts and the watch tends to gain
This is typical

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?

Watches do not like magnetism
They may lose or gain when affected by
magnetism

To make your mechanical watch work more
accurately
It is important not to leave the watch close to
magnetic objects for a long time

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

When you play golf, tennis or
baseball

When you play a sport that gives
your arm a strong impact
Please take off your mechanical
watch

There are reasons for this

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

The impact is given to your wrist
And this will affect very small parts inside your
mechanical watch

Sometimes the impact will deform or break a watch
part
“Good shot” for you becomes “bad shock” for your
watch

Love your watch, once every three years
Talk about an overhaul

In the case of a mechanical watch, there is no
need to change your battery
However
Maintenance of your watch is also necessary

Once every three years
Please take your watch to our service center
For examining and cleaning every part of your
watch

Once you start using it
Your watch never takes a rest

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 insufcient in some parts

Especially

The rst 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

An overhaul after the rst three years 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

For lifelong use of your mechanical watch rule No.3 For lifelong use of your mechanical watch rule No.5

For lifelong use of your mechanical watch rule No.6

For lifelong use of your mechanical watch rule No.4

Accuracy will vary depending on the temperature. Do not give your mechanical watch a strong shock.

Overhaul, once every three years

Keep your mechanical watch away from magnetic objects.

■NAMES OF THE PARTS

About the caliber number

The caliber number is a four-digit number that indicates the model of a
movement (mechanical part of a watch). The Grand Seiko watch is mounted
with an exclusive caliber. The mechanical caliber number starts with “9S”, the
spring drive caliber number starts with “9R” and the quartz caliber number
starts with “9F”.

※

Some quartz caliber number starts with “8J” or “4J”.

How to check the caliber number

The four-digit model number on the case back is the caliber number.

In the case of mechanical models, the attached “Grand Seiko Standard

Inspection Certicate” is printed with “Caliber No.” So, the caliber number can
also be checked on the certicate.
