■CHARACTERISTICS
You are now the proud owner of a Grand Seiko watch.
Grand Seiko watches are designed and manufactured to operate with extremely high accuracy by taking advantage of
SEIKO's more than 100 years of experience in watchmaking
52
and the advanced technology that SEIKO can boast to the
world.
To preserve the highest quality of your Grand Seiko watch,
please read the instructions in this booklet carefully for its
proper use and care, and keep this booklet for ready reference.
Spring Drive, the unique mechanism made available only by SEIKO technology, ensures
quartz accuracy while using the mainspring as its sole power source.
With Spring Drive as its basic structure, the Spring Drive Chronograph features the
world's first center chronograph second hand which works in a perfectly smooth movement.
In addition to the self-winding mechanism, which uses the natural motion of the wearer's
arm as a power source to wind its mainspring, the watch is equipped with the manual winding mechanism, which is convenient to wind the mainspring when you start using the watch.
The watch keeps working for approximately 72 hours (three days) when the mainspring is
fully wound.
The watch features the power reserve indicator to show the winding state of the mainspring.
The glide-motion small second hand that moves in a perfectly smooth movement is one of the
remarkable features of this watch.
The watch is also equipped with a 24-hour hand, offering a time difference adjustment function, which works in conjunction with the calendar.
※ For the details of the Spring Drive mechanism, refer to the separate volume "Spring Drive Handbook".
CAUTION
Spring Drive works by the power provided by the mainspring. Remember to check the power reserve indicator and keep the mainspring of the watch sufficiently wound while using the watch.
Refer to "POWER RESERVE INDICATOR" on page 62.

■HOW TO WIND THE MAINSPRING
This watch is a self-winding 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.
When first using a stopped watch, it is recommended that you manually wind the
mainspring by turning the crown.
●Guide for winding state of the mainspring
60
Self-winding::
The mainspring of the watch is designed to be fully wound when it is worn for twelve hours per day
for three to five consecutive days.
Manual winding:
Five full rotations of the crown will provide the power to run the watch for approximately ten
hours.
Observe the power reserve indicator to check the level of the remaining power.
Refer to "POWER RESERVE INDICATOR" on page 62.
※ The watch employs a device to prevent overwinding of the mainspring. Once the mainspring is fully
wound, the mainspring slips inside, disengaging the winding mechanism. When this happens, you can
still turn the crown without damaging the watch, however, please refrain from excessive operation of the
mainspring.
※ Under a low-temperature condition (below 0℃), always keep at least one-sixth of the watch power shown
by the power reserve indicator.
●How to manually wind the mainspring by turning the crown
1. Unlock the crown.
2. Slowly turn the crown clockwise (upward) to wind the mainspring with
extra care not to press it in. Wind the mainspring until the power reserve indicator shows a full-wound state. The small second hand starts
moving.
3. Once you finish winding the mainspring,
make sure you relock the crown.
※ Refer to "How to use the screw lock type crown" on page 57.
※ Refer to "How to read the power reserve indicator" on page 63.
In order to set the time and calendar after winding
the mainspring manually, do not relock the crown but
continue the procedures.
※ Refer to "How to set the time and calendar" on page 64.
61
■POWER RESERVE INDICATOR
●HOW TO READ THE POWER RESERVE INDICATOR
The power reserve indicator lets you know the winding state of the mainspring.
62
Power
Reserve
Indicator
Before removing the watch from your wrist,
observe the power reserve indicator to
check if the watch has stored enough power
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.)
Power reserve indicator
※ The continuous operable time of the watch 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.
※ In a case where you wear the watch for a short period of time, observe the power reserve indicator to check the level of the remaining power. If necessary, manually wind the mainspring.
■HOW TO SET THE TIME AND CALENDAR
To set the time and calendar, set the 24-hour hand and minute hand first,
and then set the hour hand and calendar.
●How to set the time
※ When setting the date and time, ensure that the watch is working.

●Tips for more accurate time setting
7. Turn the crown to set the hour hand.
While turning the crown, the moment the
date changes is midnight. When setting
the hour hand, be sure that AM/PM is set
correctly.
Adjust the calendar also at this point
if necessary.
66
Keep in mind the following points in order to set the time more accurately.
Refer to "How to use the screw lock type crown" on page 57.
1. Before setting the time, 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 small second hand starts to move, then pull the crown out to the
second click.
3. The small second hand will stop moving while the crown is at the second
click. Do not stop the small second hand movement for longer than 30
minutes. If the stoppage of the small second hand movement exceeds 30
minutes, push the crown back in, and wait for at least 30 seconds after the
small second hand restarts moving, and then continue the time setting.
4. To set the time during any time between 9:00 P.M. and 1:00 A.M., temporarily set the hour hand back to 8:00 P.M., and then set the time.
(This procedure is required to ensure the proper engagement of the calendar driving wheel.)

The time differences and use of daylight saving time in each region are subject to change according
to the governments of the respective countries or regions.
There are time zone differences based on time offsets from Coordinated Universal Time (UTC), which has
been internationally adopted. The world is divided into 24 time zones, and neighboring time zones have a
one-hour time difference, so that they correspond to the rotation of the earth which makes one full rotation
in 24 hours (1 day). In some regions of the world, daylight saving time is individually observed.
Daylight saving time is a system that advances the official local time by one hour during the summer to take
advantage of longer daylight hours.

CAUTION
RASH AND ALLERGY
CAUTION
CARE OF YOUR WATCH
88
The case and bracelet touch the skin directly just as underwear.
If they are left dirty, the edge of sleeve may be stained with rust of those who have a
delicate skin may have a rash.
After removing the watch from your wrist, wipe perspiration or moisture with a soft
cloth. This will prevent the watch from being soiled, adding to the life of the gasket.
Do not clean the watch with chemicals (especially with organic solvents such as
benzene, thinner, alcohol, detergent, etc.). Otherwise, the watch may be deteriorated.
Adjust the bracelet and band so that there will be a little clearance between the
bracelet or band and your wrist to avoid accumulation of perspiration.
If you are constitutionally predisposed to rash, the band may cause you to develop a
rash or an itch depending on your physical condition.
The possible cause of the rash are as follows:
1. Allergy to metals or leathers
2. Rust, dust or perspiration on the watch or band
If you develop any skin reactions, take off the watch and consult a doctor immediately.
LEATHER BAND
When removing moisture from a leather band, do not rub the band with the cloth as

●MAGNETIC RESISTANCE
●Magnetized items that may affect watches
Grand Seiko Spring Drive conforms to the Magnetic Resistance Standard ※ of JIS Class 1.
The watch has magnetic resistance to maintain performance in most cases even where it is
brought close to (at least 5cm spaced from) equipment generating a magnetic field in normal
life. However, the movement part is magnetized when it encounters a strong magnetic field,
thereby accuracy may go out of order. Pay attention so as not to bring the instrument close
to equipment (health appliances, speakers, and mobile phones using a magnet) generating a
strong magnetic field within 5cm.
