It is a time difference adjustment function to show the times of two
areas where there is a time difference in between, such as London
and Tokyo. The 24-hour hand, which takes 24hours to turn full circle on the watch, shows the time of a different time zone. Please
note that there are two different ways of using the 24-hour hand.
Choose the way of using it before setting the time.
This watch, Cal.9S56, features a time
difference adjustment function.
Two different time zones can be displayed
at the same time when you set
the hour hand and 24-hour hand respectively
in accordance with each time zone.

The 24-hour hand shows
what time of AM/PM it is now.
Set the 24-hour hand to the current time of the
place you are staying to use it as a 24-hour
display. Only by seeing the direction that the
24-hour hand shows, you can see what time
it is and whether it is AM or PM. If you set
the 24-hour hand to Japan standard time, you
can check Japan time even when you set the
hour hand and the second hand to the local
time while you are abroad. This is very convenient.

One watch, two time zones
You can see the times of
two different areas on your watch
Set the 24-hour hand to the time of an area in
different time zone from your residence. The
24-hour hand and the hour hand show two
different time zones respectively. For instance,
if you set the 24-hour hand to Greenwich
Mean Time and set the hour hand to Japan
standard time, you can always check GMT
while you are seeing the current time in
Japan.

When it is 10:00 AM in Japan,
time difference between the
Greenwich Mean Time and the
time of Japan is –9 hours, so it is
1:00 AM on the Greenwich Mean
Time.Therefore, set the 24-hour
hand to the middle point between
the 12 o’clock and 1 o’clock position, and the minute hand to the 12
o’clock position.
To set the time accurately, first turn the minute hand about 5 minutes behind of the
desired time and then advance it slowly to the correct time.
The telephone time signal service TEL.117 is helpful in setting the second hand.
The 24-hour hand shows the time of an area in a different time zone, while the current time of the place you stay is shown by the hour hand independently of the 24hour hand.To set the 24-hour hand to the time of another area in a different time
zone, repeat the steps from 01.
The time setting procedure
has been completed.
The date can be adjusted at this step. To
do so, refer to P.58
59 TO SET THE DATE.
Check that AM/PM is correctly set by turning
the hour hand past the 12 o'clock marker. If
the date changes to the next, the time is set for
the AM period. If the date does not change,
the time is set for the PM period.

Set the time
without stopping the watch.
It seems that many people do not like setting
the watch to local time when they are
abroad. Pull out the crown, stop the watch
once, set the time by turning the watch hand,
and make the second hand start according to
the time signal…these efforts are no longer
necessary if you use the time difference
adjustment function. Set the hour hand only to
local time per hour, without stopping the
minute hand and the second hand. Since the
date changes according to the hour hand, the
right date of the place you are staying can be
also displayed.

How to determine the time
differences between two areas
Before making the time difference adjustment, it is
necessary to obtain the time differences between the
two areas.
Even if the hour hand is turned to show the time of
any place, AM/PM and the date of the place may not
be adjusted properly. Before setting the hand, therefore, be sure to find the time difference between two
areas following the procedure below.
How to calculate the time differences
Assuming that you move from time zone "A" to time
zone "B" and that the time difference from GMT for the
two time zones are "a" and "b", respectively, time difference between them can be obtained from the following formula:
b a
Example If you move from Japan to New York
Time difference from GMT for Japan,
time zone A:
a 9
Time difference from GMT for New York,
time zone B:
b 5
Time difference between the two cities is:
b a 5 9 14 hours

If the daylight saving time is in effect in an area, add one hour to
the time difference from GMT before calculation.
When setting the hour hand,
other hands may move slightly.
However, this is not malfunction.
If you set the date between 10
PM and 0 AM by turning the hour
hand counterclockwise, turn the
hour hand until it shows sometime
between 9 PM and 10 PM once,
then set the date. In case the hour
hand is turned counterclockwise,
the date will be put back when the
hour hand shows around 10 PM,
however, it is not malfunction.

A mechanical watch,
which is run by a spring,
is easily influenced by the environments or
the conditions that it is used.
That affects the accuracy of
mechanical watches.
It can be said that mechanical watches are
just like living things.
Thus mechanical watches have totally
different characteristics from quartz watches.
Some of them will be shown as follows.
2
Remarks on accuracy of
mechanical watches
Page 15
IC
A quartz watch obtains power from a battery. And its accuracy is
raised by crystal and IC. On the other hand, a mechanical watch
is run by a mainspring. Small metal parts of the watch work together physically, and the accuracy of the watch is controlled by
adjusting very small parts such as hairsprings. These parts are easily affected by the outside environments such as temperatures, gravity, and shock, or by the conditions which the watch is used, such
as how long it is worn, or how many times the mainspring is wound
up. These influences appear as the loss/gain of the watch, which
is often shown by the rate such as "some seconds /day".
Mechanical watches are self-sufficient.
Small movements work together to keep
the watch ticking.

How mechanical watches work
Page 16
29
10 15
1 10
The loss/gain of quartz watches is shown by yearly or monthly
rate, such as
10 seconds/year or 15 seconds/month.
However, in case of mechanical watches, the accuracy changes
delicately day by day, depending on various conditions. Thus the
loss/gain of mechanical watches is not measured by a daily rate,
but by an average of daily rates in one week or ten days. That is
why the accuracy of mechanical watches is shown by " the mean
daily rate."
The accuracy of mechanical watches is
different between today and yesterday.
That's why it is shown by
"the mean daily rate."

The accuracy of mechanical watches varies delicately depending
on the condition in which the watch is used. The figures written in
the Grand Seiko Rating Certificate are the result of measuring
loss/gain of time for seventeen days before the inside movements
of the watch are put in the case, and the measurement has been
done in the factory where temperatures or position of the movements are controlled.
See P.61 for further information about
Grand Seiko standard.
Thus the figures showing the accuracy of
the watch will be different when it is actually worn. The accuracy
of Grand Seiko watch should be from -1 seconds/day to +10 seconds/day while it is in use. If the average of the daily rates
exceeds this level even if the watch is being used in usual life patterns, the watch will be adjusted by us.
The cost of adjusting the
watch is free for two years from the day of purchase. After that,
the cost should be charged. If the watch has been used for a long
time and parts of the movement are deteriorated, please note that
the accuracy may not be adjusted as your request.
The accuracy of mechanical watches in
use or not in use
The difference of the accuracy is shown in
two kinds of figures.

In case of mechanical watches, it is important that sufficient energy
is supplied to each movement by the mainspring of the watch. If
the spring gets unwound and supplied energy becomes less, the
parts controlling the accuracy become easily affected by outside
environments. To stabilize the accuracy, it is recommended to wind
up the mainspring everyday at a fixed time, even if the watch is
self-winding type. If the watch has stopped, turn the crown further
or swing the watch to wind up the mainspring sufficiently.
Wind the mainspring up fully to
stabilize the accuracy

The parts that consist a mechanical watch are made of metals. As
you know, metals expand or contract depending on temperatures.
The parts that controls the accuracy of the watch expands and
moves slightly slower in high temperature, and the watch tends to
lose time generally. It tends to gain time in low temperature for the
reverse reason. Please understand such conditions before seeing
the accuracy when temperature is extremely high or low, such as
midsummer or midwinter
When it is hot, the watch loses time generally.
When it is cold,
the watch gains time generally.
Changes in temperatures affect
the accuracy of the watch.

The rates of loss/gain of mechanical watches vary delicately
depending on positions they are put in, such as being placed horizontally with its face or back turned up, or being laid at a
12:00/3:00 /6:00/9:00 side respectively. This is because the
gravity of the earth affects the operation of the inside movement of
the watch. Use this character and be careful of the position of the
watch while it is not worn in order to reduce the loss/gain to some
extent by yourself, which is caused while the watch is worn.
The accuracy of the watch is
also affected by its position
when it is not worn on the wrist.

The watch may not be operating
properly because its oil keeping condition is spoiled, or the oil becomes
soiled. Contact the retailer from whom
the watch was purchased.
Reset the hour hand by 12 hours.
Water is harmful to the mechanism of
the watch. Contact the retailer from
whom the watch was purchased.
Turn the watch upside down or put it
in the different angle from usual to
wind up the crown from the other side.
Then it may be easier to wind it up.
It is necessary to adjust or change
parts of the watch. Contact the retailer
from whom the watch was purchased.
TROUBLE SHOOTING
3 3
Turn the crown or swing the watch to
wind up the mainspring. If the watch
does not start, contact the retailer from
whom the watch was purchased.
This condition will be corrected when
the watch is kept away from close contact with a magnetic object.
If this condition is not corrected by
following the above procedure, contact
the retailer from whom the watch was
purchased.
To stabilize the accuracy of the
watch, in case of a wind-up type
mechanical watch, wind it up every
day at a fixed time. In case of a selfwinding watch, wind it up sufficiently
by hand if it does not seem to be fully
wound up.

CARE OF YOUR WATCH
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.
LEATHER BAND
When removing moisture from a leather band, do not rub the
band with the cloth as they may discolor it or reduce its
gloss. Be sure to blot up the moisture using a soft dry cloth.
Please note that leather bands may become less durable
when they are moistened.
METAL BRACELET
Clean the watch bracelet with a soft toothbrush dipped in
water or soapy water.
RASH AND ALLERGY
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.
