■INTRODUCTION - Spring drive watch –
History of Spring Drive
Decades-long dream lives in the Grand Seiko
Grand Seiko’s history symbolizes the culmination of efforts and
development aiming for better practical watches.
Thank you for purchasing the Grand Seiko Spring Drive automatic
winding Model.
The Grand Seiko watch was born in 1960, reached the very top in
the mechanical watch field around the world at the end of the 1960’s.
After a hiatus of dozen years or so, in 1993, the Grand Seiko 9F
series equipped with world-class quartz movement was released. In
1998, the 9S series mechanical movement that combined traditional
craftsmanship and advanced technology was developed to reintroduce
the Grand Seiko mechanical caliber. While using the unwinding power
of the mainspring as its sole power source, the new mechanism Spring
Drive realizes an average monthly rate of ±15 seconds (For Cal. 9R15,
±10 seconds), substantially exceeding the accuracy of conventional
mechanical watches. The watch also embodies the concepts of
Grand Seiko that continues the challenge of creating the best
practical watch.
The Spring Drive is Seiko’s unique mechanism in which the
mainspring is wound by the natural motions of the user and accuracy
is controlled by a microelectronics quartz mechanism while using the
unwinding power of the mainspring to move the hands.
The Spring Drive powered by natural motions of the user can be
called a watch that strongly combines and connects the user with
the latest advancements in technology.
A mechanical watch of taste and refinement with an accuracy
equivalent to a quartz watch, this sophisticated and innovative watch
ticks in step with the pace of a person’s life.
This is a watch that creates a lifestyle for modern individuals who
seek affluence and convenience in their life.

Spring Drive Mechanism ①
Spring Drive Mechanism ②
Taste of a Mechanical Watch
＋
The power of the mainspring is regulated by electronic
control. That is the essence of the Spring Drive.
High accuracy equivalent to a Quartz Watch
That is the concept of the Spring Drive.
What controls the accuracy of a mechanical watch is
the balance spring, a part of the speed-regulating unit, called the
balance.
Let’s start from the drive method of a watch.
This part influences the accuracy to some extent
because it is made of metal which expands and contracts with
changes in temperature.
The method for driving a watch is divided into two types.
They are mechanical type and quartz type.
In a mechanical watch, the mainspring is wound and its unwinding
power moves the hands.
Amazing mechanism created by high quality workmanship,
and admiration goes to skilled craftsmen with passion.
You can feel the appreciation and personal touch of the craftsmen in
the ticking sound.
On the other hand, with quartz watches, the quartz is oscillated by a
battery and the hands are turned by a motor.
The Spring Drive is
completely different from a mechanical watch in this speed-regulating
unit.
The Spring Drive is powered by a mainspring,
but adopts an electronic speed-regulating unit comprising a
generator, IC circuit, and crystal oscillator.
It is characterized by accuracy using state-of-the-art technology.
In a little more detail,
at the end of the train wheel that moves the hands, a series of speed
increasing wheels with a rotor are provided.
The unwinding power of the mainspring rotates the rotor, generating
electricity in the coil to drive the crystal oscillator and IC.
The IC controls the spinning speed of the rotor by applying and
releasing the electromagnetic brake, while comparing the accuracy
of the electric signals generated by the crystal oscillator and the
spinning speed of the rotor.
What is the Spring Drive like?
This is not a mechanical watch or a quartz watch.
In one word, this is a“mechanical watch having accuracy equivalent
to a quartz watch.”
The Spring Drive is a self-contained drive system that realizes
accuracy equivalent to a quartz watch with only the power of the
mainspring and has no battery, motor, or secondary battery.
Accuracy of monthly rate of ±15 seconds (daily rate of ±1 second)※
equivalent to a quartz watch is achieved while using a mainspring.
The Spring Drive is Seiko’s proprietary mechanism which is made
available only by SEIKO’s unique combination of skills in both
mechanical and electronic micro-engineering.
In addition, by making the energy transfer of the train wheel efficient
and adopting an IC that drives with low power consumption and an
amorphous core with low energy loss for the coil core part, power
reserve of more than 72 hours far exceeding normal mechanical
watches is realized.
Then, how could it be possible to achieve such a degree of
accuracy?
That is explained on the next page.
An unprecedented drive system which offers quartz accuracy.
This is the Spring Drive.
※ For Cal. 9R15, the average monthly rate is ±10 seconds
(equivalent to daily rate of ±0.5 second).

Spring Drive Mechanism ③
Here is the step-by-step description of the Spring
Drive in an easy-to-understand manner.
This is how the Spring Drive works.
Differences between the Spring
Drive and mechanical watch
For the Spring Drive, the mainspring is wound and the
unwinding power of the mainspring moves the hands in
the same manner as the mechanical watch.
Mainspring
It differs from the mechanical watch only in the speed-
regulating unit (mechanism for controlling accuracy).
The mainspring is wound by rotation of the rotor (or
1
2
by turning of the crown), and its unwinding power is
the sole power source.
◎ Temperature change
Accuracy of mechanical watches depends on a balance spring attached to a
part called the balance. This part has properties for expanding and
contracting with temperature changes, and influences the accuracy of a
watch. Accuracy of the Spring Drive is never largely influenced by
temperature changes like that of mechanical watches since the crystal
oscillator controls it.
Gear train • hands
The unwinding power of the mainspring is transmitted
via the gear train to move the hands.
(Note) Accuracy of the Spring Drive
No motor or battery is mounted.
Average monthly rate of ±15 seconds (equivalent to daily rate of ±1 second)※
is the accuracy of a watch when it is worn on a wrist at a temperature range
between 5℃ and 35℃.
Tri-synchro regulator
※ For Cal. 9R15, the average monthly rate is ± 10 seconds (equivalent to daily
rate of ±0.5 second).
The unwinding power of the mainspring also rotates
the glide wheel. This generates small electricity in
the coil to drive the IC and crystal oscillator. At the
same time, an electric magnetic field is generated
on the glide wheel. The IC detects the spinning
speed of the glide wheel based on the accuracy of
the electric signals of the crystal oscillator, and
adjusts the spinning speed of the glide wheel while
applying and releasing the electromagnetic brake.
◎ Difference in position
For mechanical watches, the accuracy is influenced even by a difference in
position or direction of a watch. This is also caused by the balance that
controls the accuracy of mechanical watches. Due to the difference in
position, the area where the shaft of the balance contacts with other parts
differs, and such differences in resistance influence the accuracy. As the
Spring Drive adopts a crystal oscillator not a balance, the accuracy is not
influenced by a difference in position.
3
◎ Impact
Mechanical watches are susceptible to impacts. If a mechanical watch was
subject to impact, amplitude of vibration of the balance (angle for which the
balance rotates right and left) is changed, and even the form of the balance
spring is changed. In this regard, the Spring Drive is superior to mechanical
watches in impact resistance because it adopts a crystal oscillator not a balance.
Rotor
Mainspring
◎ Overhaul
Parts that become worn or severely damaged are the balance, pallet fork,
and escape wheel & pinion which are collectively called the speed-
regulating unit or escapement. These parts“come into contact or collide”
mutually and control unwinding of the mainspring.
For the Spring Drive, wear and damage occur less than mechanical watches
since the spinning speed of the rotor is adjusted by a“contact-free”
electromagnetic brake. However, as the structure of gear train is the same
as mechanical watches, abrasion powder may be generated by contact of
the wheels & pinions. An overhaul is recommend every three to four years.

Tips for more accurate time setting
To ensure effective operation of the Spring Drive mechanism, observe the
following instructions when you set the time.
How to set the time and date
This watch is equipped with the date display function. The date advances
one day once every 24 hours around midnight. Therefore, if AM/PM is
incorrectly set, the date will change around noon. When setting the date
and time, ensure that the watch is working.
① Before setting the time, make sure to wind the mainspring sufficiently.
(Ensure that the power reserve indicator is showing a full-wound state.)
②
When starting to use a watch after it stops, wind the mainspring sufficiently.
To set the time after that, wait for approximately 30 seconds after the
second hand (or the small second hand) starts moving, then pull the
crown out to the second click.
① Pull out the crown to the first click. (If the watch is equipped with a
screw-lock type crown, unscrew
the crown before pulling it out.)
② The date can be adjusted by
turning the crown counterclockwise
③
The second hand (or the small second hand) will stop moving when the crown

How to use the 24-hour hand
This watch has two different types of 24-hour hand usage.
⇒ "How to use the screw-lock type crown" page 16.
<Type 1> 24-hour hand as an
AM/PM indicator
Simply using the 24-hour hand
to show the 24-hour time as an
AM/PM indicator. (This is the
standard usage type for the 24-
hour hand.)
<Type 2> 24-hour hand as a dual time
indicator
※ The calendar is designed to work in conjunction with the movement of the hour
hand, therefore, if AM/PM is incorrectly set, the calendar will be off by 12
hours.
Using the time difference adjustment
function, set the 24-hour hand to
indicate a time different from the time
that the hour and minute hand indicate,
which is of a place in a different time
zone area with at least one hour of
time difference from where you are.
※ The crown can be turned in either direction to adjust the date, however, it is
recommended to turn the crown in the direction which enables you to set the
date with a smaller adjustment.
※ Turn the crown slowly, checking that the hour hand moves in one-hour
increments.
Both the hour hand and the 24-
hour hand are indicating the
Japan time 10:00 a.m.
※ When adjusting the hour hand, the other hands may move slightly. However, this
is not a malfunction.
Hour hand: Japan time 10:00 a.m.
24-hour hand: New York time 8:00 p.m.
Tips for more accurate time setting
To ensure effective operation of the Spring Drive mechanism, observe the
following instructions when you set the time.
① Before setting the time, make sure to wind the mainspring sufficiently.
(Ensure that the power reserve indicator is showing a full-wound state.)
② When starting to use a watch after it stops, wind the mainspring
sufficiently. To set the time after that, wait for approximately 30
seconds after the second hand (or the small second hand) starts
moving, then pull the crown out to the second click.
③ The second hand (or the small second hand) will stop moving when
the crown is pulled out to the second click. Do not stop the movement
of the second hand (or the small second hand) for longer than 30
minutes. If the stoppage of the second-hand (or the small-second-hand)
movement exceeds 30 minutes, push the crown back in, and wait for
approximately 30 seconds after the second hand (or the small second
hand) restarts moving, and then set the time.

Time difference adjustment function
For example, while traveling abroad and staying in a place with a different
time from where you live, you can conveniently set the watch to indicate
the local time in the different time zone area without stopping the watch.
The hour hand indicates the time of the place where you currently are,
while the 24-hour hand indicates the time of the place of origin.
The calendar works in conjunction with the movement of the hour hand. If
the time difference is correctly adjusted, the watch displays the correct
date of the place where you are staying.
④ If you set the time when the time the watch indicates is between 9:00
p.m. and 1:00 a.m., set the hour hand back to 8:00 p.m. temporarily,
and then set the time. (This procedure is required to ensure the proper
engagement of the calendar driving wheels.)

Band
Magnetic resistance (Magnetic influence)
The band touches the skin directly and becomes dirty from
sweat or dust. Therefore, lack of care may accelerate
deterioration of the band or cause skin irritation or stain on the
sleeve edge. The watch requires a lot of attention for long usage.
Affected by nearby magnetism, a watch may temporarily gain or lose time or stop operating.

○ 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 in water
and then brush it off with a soft toothbrush (Protect the watch body from
water splashes by wrapping it up 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.
The watch can maintain its performance in
most cases where it is brought close to (at
least 1cm spaced from) magnetic products
not only in normal daily life circumstances
but also in a special work environments.

○ 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.
※ A/m (ampere meter) is the International unit (SI unit) for indicating the magnetic field.
Leather band
○ A leather band is susceptible to discoloration and deterioration from
moisture, sweat and direct sunlight.
Examples of common magnetic products that may affect watches
○ Wipe off moisture and sweat as soon as possible by gently blotting
them up with a dry cloth.
○ Do not expose the watch to direct sunlight for a long time.
○ Please take care when wearing a watch with light-colored band, as dirt
is likely to show up.
○
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/20-BAR water resistant).

Polyurethane band
○ A polyurethane band is susceptible to discoloration from light, and may
be deteriorated by solvent or atmospheric humidity.
○ Especially a translucent, white, or pale colored band easily adsorbs
other colors, resulting in color smears or discoloration.
○ Wash out dirt in water and clean it off with a dry cloth. (Protect the
watch body from water splashes by wrapping it up in plastic wrap etc.)

Notes on skin irritation and allergy
If the watch becomes magnetized and its accuracy deteriorates to an
extent exceeding the specified rate under normal use, the watch may need
to be demagnetized. In this case, you will be charged for demagnetization
and accuracy readjustment even if it happens within the guarantee period.
Skin irritation caused by a band has various reasons such as allergy to metals
or leathers, or skin reactions against friction on dust or the band itself.
Notes on the length of the band
Adjust the band to allow a little clearance with your wrist to
ensure proper airflow. When wearing the watch, leave enough
room to insert a finger between the band and your wrist.
The reason why this watch is affected by magnetism
The built-in speed-regulating mechanism is provided with a magnet, which
may be influenced by a strong external magnetic field.

Troubles
Possible causes
Solutions
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.
