To wind up the mainspring by turning
the crown, turn it clockwise slowly.
The mainspring cannot be wound by
turning the crown counterclockwise.
To start the watch after it stops com-
pletely, wind up the mainspring fully
by turning the crown more than 40
times.
Please note that the crown can be
turned even after the mainspring is
wound up fully.

Due to the mechanism of mechanical watches, actual loss/gain may not fall with-
in the range of time accuracy specified above, depending on the conditions of
use, such as the length of time during which the watch is worn on the wrist, life
style whether much arm movement is involved or not , whether the watch is
wound up fully or not, temperature,etc. Refer to P.30 37
About 40 turns of the crown will wind up the mainspring of this watch fully.
Once the mainspring is wound up fully, this watch operates about 50 hours.
The specifications are subject to change without prior notice, for product improve-
ment.

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 cir-
cle 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 conve-
nient.

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.

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.

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.
2Remarks on accuracy of
mechanical watches

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 togeth-
er physically, and the accuracy of the watch is controlled by
adjusting very small parts such as hairsprings. These parts are easi-
ly affected by the outside environments such as temperatures, gravi-
ty, 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.

2 1 How mechanical watches work

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 move-
ments 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 sec-
onds/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 pat-
terns, 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 hori-
zontally 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.
