– Spring Drive watch –
History of Spring Drive
Thank you for purchasing the Grand Seiko Spring Drive 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.
That is what the Grand Seiko Spring Drive watch is all about.
Grand Seiko’
s history symbolizes the culmination of efforts and
development aiming for better practical watches.
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. 9R96,
9R16 and 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.

Spring Drive Mechanism ①
Let’
s start from the drive method of a watch.
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.
It is characterized by accuracy using state-of-the-art technology.
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.
Then, how could it be possible to achieve such a degree of
accuracy?
That is explained on the next page.
The power of the mainspring is regulated by electronic
control. That is the essence of the Spring Drive.
English
Taste of a Mechanical Watch
+
High accuracy equivalent to a Quartz Watch
That is the concept of the Spring Drive.
Spring Drive Mechanism ②
What controls the accuracy of a mechanical watch is
the balance spring, a part of the speed-regulating unit, called the
balance.
This part influences the accuracy to some extent
because it is made of metal which expands and contracts with
changes in temperature.
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.
In a little more detail,
at the end of the train wheel that moves the hands, a series of speed
increasing wheels with a glide wheel are provided.
The unwinding power of the mainspring rotates the glide wheel,
generating electricity in the coil to drive the crystal oscillator and IC.
The IC controls the spinning speed of the glide wheel 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 glide wheel.
In addition, by making the energy transfer of the train wheel efficient
and adopting an IC that drives with low power consumption, power
reserve of more than 72 hours far exceeding normal mechanical
watches is realized.
An unprecedented drive system which offers quartz accuracy.
This is the Spring Drive.
※F
or Cal. 9R96, 9R16 and 9R15, the average monthly rate is ±10
seconds
(equivalent to daily rate of ±0.5 second).

Spring Drive Mechanism ③
1
Mainspring
The mainspring is wound by rotation of the oscillating
weight (or by turning of the crown), and its unwinding
power is the sole power source.
2
Gear train • hands
The unwinding power of the mainspring is transmitted
via the gear train to move the hands.
No motor or battery is mounted.
3
Tri-synchro regulator
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.
Oscillating Weight
Mainspring
◎ 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.
(Note) A
ccuracy of the Spring Drive
A
verage 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℃.
※F
or Cal. 9R96, 9R16 and 9R15, the average monthly rate is ± 10 seconds
(equivalent to daily rate of ±0.5 second).
◎ 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.
◎ 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.
◎ Overhaul

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.
It differs from the mechanical watch only in the speedregulating unit (mechanism for controlling accuracy).
English
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
Parts that become worn or severely damaged are the balance, pallet fork,
and escape wheel & pinion which are collectively called the speedregulating 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 glide wheel 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 recommended every three to four years.

Tips for more accurate time setting
HOW TO USE (For Cal. 9R31)
○T
his watch has a manually wound spring drive.
You can wind the crown to wind the main spring to drive the watch.
○ P lease see the power reserve indicator to check the level of the
remaining power.
⇒“How to read the power reserve indicator”page 19.
○ T o wind 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. Seven full
rotations of the crown will provide the power to run the watch for
approximately ten hours.
○ When starting to use a watch after it has stopped, wind the mainspring
sufficiently (so it is fully wound).
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.)
②W

Unidirectional rotating bezel
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
①A
t the start of the activity, for which you want to measure the elapsed
time (for example, when you start diving), rotate the bezel so that the
mark on the bezel is aligned with the minute hand.
②R
ead the graduation on the rotating bezel to which the minute hand is
pointing.
【Ex.】When you start diving at 10:10.

Lumibrite
Troubleshooting
Troubles
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.
※ In general, when you enter a dark place from a bright environment, your eye
cannot adapt to the change in light levels quickly. At first, you can hardly see
anything, but as time passes, your vision gradually improves. (Dark adaptation of
the human eye)
