QUICK MOVEMENT OF

SEIKO KINETIC Cal. 5M54 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.
1. When the watch stops completely, or if you find
the second hand moving at two-second intervals,
swing the watch from side to side at a rate of
twice a second.
1. By swinging the watch
2. By using the KINETIC Energy Supplyer YT02A
2. 250 swings will reserve up to 1 day of power.
The second hand will start moving at one-second intervals.
Set the crown to the 5M position.
•Make sure that the watch is correctly
positioned as it may affect the amount of
power generated.
•The amount of power generated may vary
depending the models of the watch.
5M
Cal. 5M54A is equipped with a power reserve indicator. The current power reserve can be checked by
reading the posisiton of the second hand after pressing the button at the 2 o'clock position.
* The second hand will resume normal movement after the indicated 5, 10, 20 or 30 seconds have
elapsed.
* To allow easy reading of the second hand, press the button when the second hand is at the 12 o’clock
position.
* It is recommended that the watch be swung further until 2 days of power is reserved. As a
guideline of recharging, additional 200 to 250 swings, about 450 to 500 swings in total will
reserve 2 days of power.

36 RECHARGEABLE BATTERY UNIT
Though the RECHARGEABLE BATTERY UNIT for Cal. 5M54 and 5M6 Series is of a completely
different type from the CAPACITOR UNIT for Cal. 5M4 Series, they have a close resemblance in
shape. They can be discriminated by the shapes of their minus lead terminals as illustrated below.
When repairing the RECHARGEABLE BATTERY UNIT, check the shape of its minus lead terminal to
make sure you are using a RECHARGEABLE BATTERY UNIT properly.

The CIRCUIT BLOCK for Cal. 5M54 and 5M6 Seriesand thatfor Cal. 5M4 Series have a close resemblance
in shape. They can be discriminated in the point that the CIRCUIT BLOCK for Cal. 5M54 and 5M6
Series has no diode element unlike that for Cal. 5M4 Series. When repairing the CIRCUIT BLOCK,
check that it has no diode element to make sure you are using the proper one.

The GENERATING COIL BLOCK for Cal. 5M54 and 5M6 Series and that for Cal. 5M4 Series have a close
resemblance in shape. They can be discriminated by the size of the pattern on the lead terminal. If
the GENERATING COIL BLOCK for Cal. 5M4 Series is assembled by mistake, no electricity will be
generated. When repairing the GENERATING COIL BLOCK, check the size of the pattern on the lead
terminal to make sure you are using the proper one.

lHow to remove/install the contact point spring
4 CONTACT POINT SPRING
The CONTACT POINT SPRING has three hooking
portions bent downward. It is fixed by inserting
the hooking portion “A” into a gap between the
MAIN PLATE and HOLDING RING FOR DIAL and
inserting “B” and “C” into a gap between the
HOLDING RING FOR DIAL and CASE. “B” “A” “C”
* Before disassembling or assembling the CONTACT POINT SPRING, be sure to remove the
SETTING STEM.
• How to remove
Insert the tip of tweezers into the gaps between the hooking portions “A”, “B” and “C “ of the
CONTACT POINT SPRING and HOLDING RING FOR DIAL, and pry up the CONTACT POINT SPRING
slowly to remove it.
•How to install
1) Push the hooking portion “A” in the
direction of the arrow in the illustration
at right to insert it into a gap between the
MAIN PLATE and HOLDING RING FOR
DIAL.
2) Insert the hooking portions “B” and “C”
into a gap between the HOLDING RING
FOR DIAL and CASE.
In doing so, the installation will be
made more easily by pushing down the
CONTACT POINT SPRING while slightly
lifting it up so that the tips of the hooking
portions “B” and “C” are tilted toward the
HOLDING RING FOR DIAL.
Note: When removing or installing the
CONTACT POINT SPRING, take utmost
care not to deform its shape.

How to measure the current consumption for the whole movement
1. Remove the RECHARGEABLE BATTERY
UNIT (36), an INSULATOR (35) and the
BATTERY CLAMP WITH SCREWS (33) and
(34), then reassemble the OSCILLATING
WEIGHT WHEEL (32) and OSCILLATING
WEIGHT (31) and tighten the SCREW (30)
temporary in order to make the movement
ready for measurement.
2. Connect the (-) probe of the tester to the
input terminal (-) of the CIRCUIT BLOCK
and (+) probe to the other metal part of
the movement, such as CIRCUIT BLOCK
COVER. “a” portion

* When measuring the current consumption using
the SEIKO digital multi-tester (S- 860), use the
range of 40 μ A of SUPPLY V (= 1.55 V) &

for more than three seconds so that the movement
detects the electricity generation and it turns to the
normal hand movement mode.
Note: When swinging the OSCILLATING WEIGHT, take
care so as not to touch the probes of the tester.
4. Wait for more than 10 seconds until a stable measurement is obtained, and then read the

1. To measure the current consumption for the CIRCUIT BLOCK alone, connect each probe to the
appropriate positive (+) or negative (-) input terminal of the CIRCUIT BLOCK (please refer to
“Structure of the circuit block” below).
*When measuring the current consumption using
the SEIKO digital multi-tester (S- 860), use the
range of 40 μ A of SUPPLY V (= 1.55 V) &

2. In order to turn the mode of the C-MOS-IC into the normal hand movement mode, short-circuit
it by touching “A” portion and the input terminal (-) with tweezers for more than three seconds.
*When measuring the current consumption for the CIRCUIT BLOCK alone, be careful not to damage
or deform the pattern of the CIRCUIT BLOCK.
3. Read the measurement when a stable measurement is obtained.

• 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 short-circuit the lead
terminal (-) and the RECHARGEABLE
BATTERY CLAMP.
*If a short-circuit has occurred, leave
the watch untouched for more than 10
minutes,andmeasurethe voltageagain,
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.
