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.)
SEIKO KINETIC Cal. 7D46/7D48/7D56 is an analogue quartz watch equipped with the
Kinetic technology developed by SEIKO. It generates the electric energy to power the
watch, utilizing the movement of your body, and stores it in the rechargeable battery,
which requires no periodical replacement unlike conventional button-type batteries.
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.
POWER SAVE FUNCTION AND TIME RELAY FUNCTION
●
●
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.
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 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
● 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.
(
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.

Kinetic System. The watch also features the “power save function,” 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.

✽
✽
Do not pull the crown out to the second click position while the watch is in power save mode.
This will cancel the power save function causing the time data retained in the watch to be
erased.
Do not leave the watch with its crown being at the second click position, as the watch
consumes greater energy than it uses while it is in power save mode.
■ TIME RELAY FUNCTION
●
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.
●
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.
<Remarks on Power Save Function>
●
When the watch is left untouched for approximately 24 hours (approximately
one day), the power save function is automatically activated.
✽ While the second hand is moving at two-second intervals, the power save function
cannot be activated.
✽
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 11 or “IF THE SECOND HAND STARTS MOVING AT TWO-SECOND
INTERVALS” on page 19. )
●
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.
✽ 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 19.)

SCREW LOCK TYPE CROWN
●
HOW TO WAKE UP THE WATCH FROM POWER SAVE MODE
●
In order to “wake up” the watch from power save mode, swing the watch gently
from side to side to recharge it.
Some models have the screw lock type crown, which can be locked by the screw
when it is not necessary to be operated.
✽
Do not pull out the crown to the second click position before performing the following
procedures. This will cancel the time relay function.
●
●
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.
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.
■ HOW TO OPERATE THE SCREW LOCK TYPE CROWN
If your watch has a screw lock type crown, unscrew it before any crown operation.
✽
No additional benefit is obtained by swinging the watch with
greater vigor.
❖
Always keep the crown locked unless it is necessary for operating the crown.
[To unscrew the crown]
✽
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.
Turn the crown counterclockwise (down-
ward) to unscrew it. The crown is unlocked
and can be operated.
The crown can be pulled out.
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.
[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.
The second hand
remains still.

■ HOW TO SET THE TIME
Notes
[Cal. 7D46]
1. Pull out the crown to the second click.
The second hand will be stopping on
the spot.
✽
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.
✽
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 19. )
✽
If your watch has a screw lock type
crown, unscrew the crown first, and
then pull it out to the second click.

■ HOW TO SET THE PERPETUAL CALENDAR
CAUTION
●
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.
● Avoid setting the time or calendar at a time between 23:00 and 1:00.
✽
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.
✽
The calendar can be adjusted by turning the crown in either direction upward or downward
at the first click position.
● While the watch runs in normal operation, the date changes during the time
between 23:30 and 0:30.
<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 indicator rotates to show the following year.
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.
✽
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 indicator may not
be correctly aligned. In that case, set the calendar back to November then forward it to
the correct date in December.

IF THE SECOND HAND STARTS MOVING AT TWO-
SECOND INTERVALS
(ENERGY DEPLETION FOREWARNING FUNCTION)
●
●
●
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
rechargeable battery, and then reset the time and calendar.

4. Turn the crown to set the month display hand to indicate the correct month. Then
continue to turn the crown to set the date.
shown in the illustration below.
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.
Example: Date display of the 26th
✶
After swinging the watch, check that the second hand is moving
at one-second intervals.
5. Upon completion of the calendar adjustment in sequence of year, month and date,
push the crown back into the original position.

✽
To charge the rechargeable battery 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 rechargeable battery 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.
POWER SOURCE (RECHARGEABLE BATTERY)
This watch requires no periodic battery replacement as it is powered by the exclusive
rechargeablebattery,whichiscompletelydifferentfromconventionalbatteriesforwatches.
This exclusive rechargeable battery is an environmentally friendly, clean energy storage
device.
✽
✽
2. It is recommended that the watch be swung further until it can reserve enough
power to run the watch for approximately one day.
CAUTION
Never install a silver oxide battery for conventional watches in place of the
rechargeable battery, which can generate heat that can cause bursting or
ignition.
As a guideline, 200 swings will generate the power to run the watch for approxi-
mately one day.
POWER RESERVE GUIDELINES FOR THE
RECHARGEABLE BATTERY
NOTES ON OVERHAUL
The watch is a precision device. If the parts run short of oil or get worn out, the watch
may stop its operation or lose time. We recommend you have the watch overhauled
periodically to keep it running accurately.
●
Wearing the watch continuously for 12 hours will accumulate power to run the
watch for approximately one and a half additional days.
✽
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.
