REMARKS ON REPAIRING CAL. 5J32A
Cal. 5J32A is an epoch-making model of SEIKO’s revolutionary KINETIC watches, just like 5J21A/5J22A. It
is equipped with innovative functions that have introduced a completely new concept into the KINETIC
technology SEIKO has cultivated in its long years of precision product manufacturing. In repairing Cal.
5J32A, therefore, you are requested to have the full knowledge of its functions and strictly observe the
repairing and checking instructions provided in this guide so that the watch will be repaired securely.
FEATURES OF CAL. 5J32A
Cal. 5J32A features the power save function that automatically stops the hands from moving if the watch is
left untouched for a certain period of time. When you decide to use it again, swinging the watch several times
will activate the time relay function, which starts the hands moving quickly to indicate the correct time and
resume the normal operation. In this way, Cal. 5J32A conserves the stored electrical energy by stopping the
hands while it is not in use, and, at the same time, it completely eliminates the cumbersome time setting
procedure when it is used again.
Thanks to this innovative mechanism, the duration of charge has increased enormously.
1.
POWER SAVE FUNCTION
· While the watch is not in use, the hands stop automatically to minimize the electrical energy
consumed. This is called “the power save function”. Though the hands stop, the built-in IC continues
to compute the time, keeping the watch ready for the next use.
· The power save function can be activated either automatically or manually.
The automatic power save function
· If the watch is left untouched for approximately 72 hours, the power save function is automatically
activated.
The manual power save function
· The power save function can be activated whenever you decide no to use the watch for a long time.
· By pulling out the crown to the first click and pushing it in to the normal position within one second,
the power save function is activated manually.
Notes:
* Do not pull out the crown to the second click while the power save function is in operation. Otherwise,
it is turned off, and the time retained inside the watch will be erased.
* While the second hand is moving at two-second intervals, the power save function cannot be activated
manually.
2.
TIME RELAY FUNCTION
· While the power saving function is working, the built-in IC continues to compute the time though the
hands stop. As the watch detects a certain amount of electricity generated by swinging it, the hands
are automatically adjusted to the time retained inside the watch, resuming the normal operation. This
is called the “time relay function”. As it is activated, the hour and minute hands are adjusted first, then,
followed by the second hand.
· By only swinging the watch for 2 to 3 seconds, the time relay function will be activated.
Notes:
* The time relay function will not adjust the date. If you find the date incorrect after it is activated, it is
necessary to adjust the date manually to the current date.
* The accuracy of the time computation by the built-in IC is equivalent to that of conventional quartz
watches. If the power save function has been in operation for a long term before the time relay function
is activated, the time indicated by the hands may include a certain amount of time loss or gain that has
accumulated during that time.
3.
DURATION OF CHARGE
· The duration of charge varies depending on the power reserve stored inside the watch. If the watch
is fully charged, the power save function will keep it operating for about four years.
Note: If the power reserve is depleted completely while the power save function is in operation, the time
relay function may not be activated by swinging the watch. Instead, the second hand starts moving
at two-second intervals.

VALUE CHECKING AND ADJUSTMENT
● Coil block resistance
Second coil block

2.00 KΩ ~ 2.45 KΩ
Hour and minute coil block :
Coil for driving hands
: 1.00 KΩ ~ 1.20 KΩ
Coil for detecting generation : 280 Ω ~ 360 Ω
Note: Measure the coil block resistance after installing each coil block to the movement, checking that
stable measurements may be obtained.
* The motor driving the hour and minute hands uses a special driving system so that they move quickly
to indicate the current time immediately after the time relay function is activated. The hour and minute
coil block has two layers of coils, one for driving hands and the other for detecting generation, and it is
necessary to measure the resistance of each layer of coil.
• The illustration below shows the patterns to which the probes of the tester should be applied to measure
the resistance of the respective coils.

● Checking for leakage between coil for driving hands and coil for detecting generation
* If the hour and minute hands do not move properly when the time relay function is activated, that is, if
they remain stopped or will not move smoothly, check for the leakage between coil for driving hands
and coil for detecting generation. This checking is required only if such a problem is found.
If leakage is detected, replace the hour and minute coil block with a new one.
How to check the leakage
1.
Make the tester ready for measuring the resistance.
2.
Apply the probes of the tester to 1 “A” and “a”, 2 “A” and “b”, 3 “B” and “a”, and 4 “B” and
“b”, respectively, to measure the resistance.
3.
If the four measurements obtained are all infinitely great, that is, if the resistance was unable to be
measured for all the four cases, there is no leakage between coil for driving hands and coil for
detecting generation. As a guideline, there is a leakage if measurements of less than 2 KΩ were
obtained.
● Generating coil block resistance
340 Ω ~ 440 Ω
Note: Measure the generating coil block resistance after installing it to the movement, checking that
stable measurements are obtained.

● Current consumption
For the whole movement
(while the hands are moving):
Less than 0.70 µA (with 1.55 V supplied from a battery)
For the circuit block alone
Less than 0.13 µA (with 1.55 V supplied from a battery)
:
* The current consumption for the circuit block alone is approximately equivalent to that obtained while
the power save function is in operation.
If the duration of charge is shorter than normal while the watch is left untouched, it is necessary to
measure the current consumption while the power save function is in operation. In that case, however,
measure the current consumption for the circuit block alone instead to decide if the watch is defective
or not.
How to measure the current consumption for the whole movement (while the hands are moving)
1.
Disassemble unnecessary parts to make the movement ready for the measurement.
Follow the disassembling procedure illustrated in this manual until you remove the rechargeable
battery unit, and then, reassemble the oscillating weight. As a result, the rechargeable battery unit,
insulator for rechargeable battery and rechargeable battery clamp are removed from the movement.
2.
Apply the minus terminal to “a” portion in the illustration and plus terminal to the circuit block cover
A, respectively.
“a” portion
Circuit block cover A
3.
For a few seconds after the probes of the tester are applied to the movement, the IC is in the quick
start mode, and current consumption cannot be measured properly. To switch the IC from the quick
start to the normal hand movement mode, move the oscillating weight from side to side continuously
for more than three seconds with the tester connected to the movement. The IC will detect the
electricity generation and will be switched to the normal hand movement mode.
Note: When moving the oscillating weight from side to side, take care lest the minus terminal of the
tester touches the oscillating weight.
Oscillating weight
4.
16
After checking that the IC has been switched to the normal hand movement mode and a stable
measurement can be obtained, read the measurement.
If the measurement value remains high or unstable, repeat step “3” above.
TECHNICAL GUIDE
Cal. 5J32A
Notes:
* Light may increase the current consumption, resulting in an inaccurate measurement. If the current
consumption exceeds the standard value, protect the movement from light with a black cloth or the
like after following step “3” above, and make a measurement again.
* When the current consumption for the whole movement exceeds the standard value while the current
consumption for the circuit block alone is within the standard value range, a driving pulse may be
generated to compensate for the heavy load applied on the gear train, etc. In that case, overhaul and
clean the movement parts, and then, measure the current consumption for the whole movement again.
How to measure the current consumption for the circuit block alone
1.
Connect the tester to the circuit block as shown in
the illustration.
“A” portion
2.
With the tester connected to the circuit block, short-circuit “A” portion in the illustration and the input
pattern (–) with a conductive tweezers for approximately 1 second. The IC will be switched from the
quick start to the normal hand movement mode.
3.
Checking that a stable measurement is obtained, read the current consumption.
Notes:
* The current consumption measurement for the circuit block alone is particularly susceptible to light,
and a value higher than the actual measurement may be obtained if the circuit block is exposed to light.
Protect the circuit from light with a black cloth or the like after following step “2” above, and then,
measure the current consumption.
* If the current consumption for the circuit block alone exceeds the standard value, the duration of the
charge will be shorter than specified. In that case, replace the circuit block with a new one.
● Checking the automatic generating system
1.
Apply the probes of the tester as shown in the
illustration, and measure the voltage of the
rechargeable battery. The obtained voltage is called
the “initial voltage”.
Notes:
* When applying the minus probe of the tester to
the rechargeable battery, take care not to shortcircuit the lead terminal (–) and the rechargeable
battery clamp.
* If a short-circuit has occurred, leave the watch
untouched for more than ten minutes, and
measure the voltage again, checking that a stable
measurement is obtained.

2.
Close the case back tentatively, and swing the watch
from side to side 200 times at a rate of 2 to 3 swings a
second, making an arc of approximately 20 cm.
3.
Within 3 minutes after swinging the watch, measure
the voltage of the rechargeable battery in the same
manner as in step “1” above.
4.
Refer to the table below, and decide whether the automatic generating system is normal or defective.

After charging, the voltage of rechargeable battery has increased 0.1 V or
more from the initial voltage.
1.01 V ~ 1.2 V
After charging, the voltage of rechargeable battery has increased 0.05 V or
more from the initial voltage.
* The guidelines specified in the above table apply only when the initial voltage is within the range
between 0.45 V and 1.2 V.
* The amount of electricity generated by swinging the watch varies depending on the manner in which
you swing it, such the rate of swinging and the size of the swinging arc. Please note, therefore, that
checking through the procedure above provides only the guideline of normal/defective decision.
[ For your information ]
1.
Number of swings and power reserve
· When the power reserve in the rechargeable battery is depleted and the watch stops completely,
swinging it approximately 500 times at a rate of 2 to 3 times a second will start the second hand
moving at normal one-second intervals instead of two-second intervals. If the second hand still
moves at two-second intervals after 500 swings, swing the watch further until it moves at onesecond intervals.
· While the second hand is moving at one-second intervals, approximately 200 swings will reserve
up to one day of power.
2.
The number of days over which the watch is worn and power reserve
· Wearing the watch continuously for 12 hours will accumulate approximately one and a half
additional days of power reserve.
If you wear the watch every day for 12 hours over a period of a week, approximately 10 days of power
reserve will be secured in the rechargeable battery. While the power saving function is in operation
and the hands are stopped, this amount of power reserve will keep the watch operating for
approximately 2 months.
● Checking the manual power save and time relay functions
Cal. 5J32A is equipped with the automatic and the manual power save functions to conserve the stored
energy and the time relay function to start the hands moving to indicate the current time as the power
save function is canceled.
Note: The checking procedure below can be performed only while the watch is operating. If the watch
stops completely, swing the watch until the second hand starts moving at one-second intervals.
Swing it further more than 200 times, and then, proceed to the checking procedure.

Checking procedure
1.
Adjust the time of the watch to a base time indicated
by another watch.
2.
Pull out the crown to the first click and push it back
in to the normal position within one second. The
manual power save function is activated, and the
second hand stops moving.
Normal position
First click
Notes:
* Take care not to pull out the crown all the way
to the second click.
* If this happens by mistake, resume the checking
procedure from step “1”.
(Pull out the crown and push it
back within one second.)
3.
Leave the watch untouched for more than one
minute, making sure that the power save function
is in operation.
4.
Swing the watch continuously for 2 to 3 seconds. The watch detects the generation of electricity, and
the hands move to indicate the current time.
5.
If the time indicated by the watch is identical with the base time used in step “1”, the manual power
save and time relay functions are normal.
Note: If the power save function has been in operation for a long term before the time relay function
is activated, the time indicated by the watch and the base time may differ slightly though the
watch is normal. This is because the two watches are different in time accuracy and different
amounts of time loss or gain have accumulated during that time.
IV. TROUBLESHOOTING GUIDE
The following are the tips on repairing Cal. 5J32A, which you will find helpful in working on the watch.
Important functions characteristic of Cal. 5J32A
1)
The power save function is activated after the watch is left untouched for approximately 72 hours.
2)
The manual power save function is activated by pulling out the crown to the first click and pushing
it in to the normal position within one second.
3)
While the second hand is moving at two-second intervals, the power save function cannot be
activated either automatically or manually.
4)
If the crown is pulled out to the second click while the power save function is in operation, the time
computed by the built-in IC will be canceled, thus disabling the time relay function.
5)
The built-in IC does not compute the date, and the time relay function will not adjust the date. If the
power save function has been active for more than one day before the time relay function is activated,
it is necessary to adjust the date to the current date.
6)
The accuracy of the time computed by the built-in IC while the power save function is in operation
is equivalent to that of conventional quartz watches. If the power save function has been active for
a long term before the time relay function is activated, the time indicated by the hands may include
a certain amount of time loss or gain that has accumulated during that time.
7)
If the power reserve is depleted while the power save function is in operation, the time relay function
may not be activated by swinging the watch, Instead, the second hand starts moving at two-second
intervals.
