PERPETUAL CALENDAR FUNCTION
FEATURES
●
Once set, the calendar automatically adjusts for odd and even months including
February of leap years. (Exceptionally, the manual adjustment at the end of
February is required for the years that are divisible by four but are not leap years,
which comes only once every hundred years, for example, the year 2100.)
Unlike the conventional quartz watch powered by the button-type battery, the
KINETIC is an analog quartz watch equipped with an Automatic Generating System,
the unique technology developed by SEIKO, which generates electrical energy to
power the watch by utilizing the movement of the arm or wrist, and stores it in the
KINETIC ELECTRICITY STORAGE UNIT (KINETIC E.S.U.) The watch is provided with
the following additional functions.
✽
It takes approximately two seconds for the calendar to change its display. However, it may
take two minutes if the temperature is low or the stored electrical energy is being depleted.
●
●
While the watch is in power save mode, the perpetual calendar continues to
function.
Even if the watch is completely stopped due to a shortage of stored electrical
energy, the calendar can be manually adjusted by simple procedures.
POWER SAVE FUNCTION AND TIME RELAY FUNCTION
In order to conserve the stored electrical energy, the watch automatically enters
power save mode to stop the hands from moving approximately 24 hours after the
watch is taken off the wrist. When you
decide to wear the watch again, simply
swinging the watch several times will
awaken it and the hands will indicate the
correct time to resume normal operation.
CAUTION
● The movement of your arm while the watch is worn generates electrical energy
to power the watch. Even if the watch is worn on your arm, it will not be charged
while your arm is not in motion.
❖
The time retrieved by the time relay function
may include a certain amount of time loss or
gain within the range of accuracy of the watch
( ± 15 seconds per month).
● It is recommended that the watch be worn on your wrist daily for at least 10
hours.
❖
In a case that the fully charged watch enters
the power save mode, the time relay function
of the watch remains operable for
approximately four years.
❖
THE KINETIC E.S.U. is an abbreviation for KINETIC ELECTRICITY STORAGE UNIT, which is the
name of the power source employed in the KINETIC movements.

●
When the watch is in power save mode, swinging the watch several times will
activate the “time relay function,” which automatically resets the watch hands
to the correct time that has been retained inside the watch.

✽ While the second hand is moving at two-second intervals, the power save function
cannot be activated.
Month indicator
24-hour indicator
❖
Orientation of the displays of year, month and 24-hour indicator may vary depending on the
model.
●
When the power save function is activated, the hour, minute, second and 24-
hour hands will stop moving.
✽ While the watch is in power save mode, the calendar continues to function normally.
BEFORE INITIAL USE
✽ When the watch is left untouched in power save mode and if the date does not change
correctly, the stored electrical energy is being depleted. Recharge the watch until the
watch resumes the usual one-second interval movement, and then reset the time and
calendar before starting to wear it again.
✽ When the watch wakes up from power save mode while it is running on extremely low
electrical power, the second hand starts moving at two-second intervals. (Refer to “IF
THE SECOND HAND STARTS MOVING AT TWO-SECOND INTERVALS” on page 17.)
■ POWER SAVE FUNCTION
●
This watch is powered by electrical energy generated and stored by the built-in
Automatic Generating System. The watch also features the “power save func-
tion,” which automatically stops the hands from moving when the watch is not
in use for a certain period of time to minimize the electrical energy consumption.
When the watch is in power save mode, the hands stop moving but the built-in IC
continues to calculate the time and calendar.

■ TIME RELAY FUNCTION
SCREW LOCK TYPE CROWN
●
●
When the watch is in power save mode, the hands stop moving but the built-in IC
continues to calculate the time. When a certain amount of electrical power is
generated, the watch hands are adjusted automatically to the time retained inside
the watch.
Some models have the screw lock type crown, which can be locked by the screw
when it is not necessary to be operated.
●
●
Locking the crown will prevent operating errors.
Unscrew the crown before any crown operation. When the operation is over,
screw the crown in to lock.
●
The operable time of the time relay function varies depending on the electrical
energy stored inside the watch. In a case that the fully charged watch enters the
power save mode, the time relay function of the watch remains operable for
approximately four years.
■ HOW TO OPERATE THE SCREW LOCK TYPE CROWN
If your watch has a screw lock type crown, unscrew it before any crown operation.
❖
Always keep the crown locked unless it is necessary for operating the crown.
✽
If the stored electrical energy is completely depleted while the watch is in power save mode,
swinging the watch will not activate the time relay function. Instead, the second hand starts
moving at two-second intervals. (Refer to “HOW TO WAKE UP THE WATCH FROM POWER
SAVE MODE” on page 10 or “IF THE SECOND HAND STARTS MOVING AT TWO-SECOND
INTERVALS” on page 17. )
[To unscrew the crown]
Turn the crown counterclockwise (down-
ward) to unscrew it. The crown is unlocked
and can be operated.
The crown can be pulled out.
[To screw the crown in]
Upon completion of the crown operation,
screw the crown in completely until it stops
by turning it clockwise (upward) while gen-
tly pressing it back into the original position.
Turn the crown while pressing
it back in.

HOW TO WAKE UP THE WATCH FROM POWER SAVE MODE
Notes
●
In order to “wake up” the watch from power save mode, swing the watch gently
from side to side to recharge it.
✽
If there is any time difference between the factory default time settings and the local time
in your area, reset the time and calendar before initially using the watch after purchase.
✽
Do not pull out the crown to the second click position before performing the following
procedures. This will cancel the time relay function.
✽
While the watch is in power save mode, the built-in IC computes the time internally at an
accuracy of ±15 seconds per month which is equivalent to the accuracy of conventional
quartz watches. Therefore, the time relayed from the built-in IC to the hands by the
automatic time relay function may include a certain amount of time loss or gain within the
range of the accuracy of the watch (±15 seconds per month.) In such a case, reset the time
as needed before starting to wear the watch.
When the watch wakes up from power save mode while it is running on extremely low
electrical power, the second hand starts moving at two-second intervals. (Refer to “ IF THE
SECOND HAND STARTS MOVING AT TWO-SECOND INTERVALS“ on page 17. )
Swing the watch from side to side approximately 4 to 6 times rhythmically at
a rate of twice a second, making an arc of about 20 cm as shown in the
illustration below.
✽
✽
No additional benefit is obtained by swinging the watch with
greater vigor.
✽
When the watch is swung, the oscillating weight in the generating
system rotates to drive the mechanism. As it rotates, it gives out
a sound, which is not a malfunction.
1. Only the hour, minute and 24-
hour hands move quickly to indi-
cate the current time which has
been internally retained in the
built-in IC.
2. Then the second hand will follow
quickly to resume the normal
movement.
The second hand
remains still.

2. Turn the crown to set the time.
HOW TO SET THE TIME AND CALENDAR
✽
Remember to check the 24-hour indicator to correctly set AM/PM.
●
If there is any time difference between the factory default time settings and
the local time in your area, reset the time and calendar before initially using
the watch after purchase.
✽
To set the time accurately, advance the minute hand 4 to 5 minutes ahead of the correct time,
and then turn it back to the exact time.
3. Push the crown back into the original position. The watch immediately starts
ticking.
●
In a case that the watch is completely stopped due to a shortage of stored
electrical energy, recharge the watch until the second hand resumes the
normal one-second interval movement, and then reset the time and calen-
dar. (Refer to “IF THE SECOND HAND STARTS MOVING AT TWO-SECOND
INTERVALS” on page 17.)
✽
To set the second hand exactly, push the crown back into the original position in accordance
with a time signal.
CAUTION
■ HOW TO SET THE TIME
● Avoid setting the time or calendar at a time between 23:00 and 1:00.
1. Pull out the crown to the second click. The second hand will be stopping on the spot.
✽
If you adjust the time or calendar at a time between 23:00 and 1:00, and the date is
incorrectly advanced or delayed one day, readjust the watch avoiding the above period
of time.
✽
If your watch has a screw lock type crown, unscrew the crown first, and then pull it out to
the second click.
✽
To set the second hand exactly, pull out the crown to the second click at a moment the
second hand is pointing to the 12 o’clock (“ 0 ” second) position.
● While the watch runs in normal operation, the date changes during the time
between 23:30 and 0:30.

1. Each calendar item should be adjusted in sequence of year, month and then date.
Pull out the crown to the first click.
■ HOW TO SET THE PERPETUAL CALENDAR
●
Date, month and year are interlocked on the perpetual calendar. To set the month
or year, advance the date by turning the crown until the month or year becomes
adjustable.
✽
If your watch has a screw lock type crown, unscrew the crown first, and then pull it out to
the first click.
✽
The calendar can be adjusted by turning the crown in either direction upward or downward
at the first click position.
<Remarks on month, year settings>
When the date advances to change to “ 1 ,” the month indicator rotates for one
month to indicate the following month. When the date advances further until the
month indicator moves forward from December (DEC) to January (JAN), the
year display dial rotates to show the following year.
Crown at the first clock position
2. Turn the crown until the year becomes adjustable.
✽
Each calendar item becomes adjustable in sequence of date, month and then year, by turning
the crown.
CAUTION
● When setting the calendar in the direction backward, put the date back for one
or two days behind the date you wish to set, and then advance it to the desired
date.
✽
✽
The calendar can be adjusted by turning the crown in either direction upward or downward.
The year display dial shows the number of the year(s) past since the last leap year. When
setting the year, check whether the year you are going to set is a leap year or not, if it is not
a leap year, check how many years have passed (1, 2 or 3) since the last leap year.
✽
Follow the above procedure for setting the calendar in the direction backward, otherwise
the date numeral may not appear in the center of the calendar frame. Even though this
happens, the date display will be aligned correctly the following day.
✽
When setting the calendar backward to dates in December, the year display may not
appear in the center of the calendar frame. In that case, set the calendar back to
November then forward it to the correct date in December.

When the second hand starts moving at two-second intervals whether it is worn
or left untouched, the watch may run down within approximately 12 hours.
When the watch wakes up from power save mode while it is running on extremely
low electrical power, the second hand starts moving at two-second intervals.
In such a case, swing the watch from side to side to sufficiently charge the KINETIC
E.S.U. (Refer to “HOW TO CHARGE THE WATCH” on page 18), and then reset the
time and calendar.

■ HOW TO CHARGE THE WATCH
1. Swing the watch from side to side rhythmically at a rate of twice a second as
shown in the illustration below.
P
OWER RESERVE GUIDELINES FOR THE KINETIC E.S.U.
●
Wearing the watch continuously for 12 hours will accumulate power to run the
watch for approximately one and a half additional days.
This movement will recharge the watch to start moving at the normal one-second
intervals from the two-second interval movement. If you find the second hand
moving at two-second intervals after swinging the watch, swing it further until the
second hand moves at the normal one-second intervals.
✽
As a general guideline, if you wear the watch every day for 12 hours over a period of a week,
the power to run the watch for approximately ten days will be additionally secured. If the
watch enters the power save mode, this amount of energy will keep the watch running for
approximately one month and a half.
POWER SOURCE (KINETIC E.S.U.)
This watch requires no periodic battery replacement as it is powered by the exclusive
secondarybattery,whichiscompletelydifferentfromconventionalbatteriesforwatches.
✶
After swinging the watch, check that the second hand is moving
at one-second intervals.
This exclusive secondary battery is an environmentally friendly, clean energy storage
device.
CAUTION
✽
To charge the KINETIC E.S.U. efficiently, swing the watch from side to side rhythmically at
a rate of twice a second, making an arc of about 20 cm.
No additional benefit is obtained by swinging the watch more quickly or with greater vigor.
When the electrical energy stored in the KINETIC E.S.U. is completely depleted after the
watch is left untouched for a long time, the watch requires at least 450 swings to generate
power to resume the normal operational movement.
Never install a silver oxide battery for conventional watches in place of the
KINETIC E.S.U. , which can generate heat that can cause bursting or ignition.
✽
✽
2. It is recommended that the watch be swung further until it can reserve enough
power to run the watch for approximately one day.
As a guideline, 200 swings will generate the power to run the watch for approxi-
mately one day.
