SEIKO KINETIC Cal. 5M54 is an analogue quar tz 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 tha t the w atch i s 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.

different type from the C
APACITOR 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 R
ECHARGEABLE BATTERY UNIT, check the shape of its minus lead terminal to
make sure you are using a R
ECHARGEABLE BATTERY UNIT properly.

in shape. They can be discriminated in the point that the C
IRCUIT BLOCK for Cal. 5M54 and 5M6
Series has no diode element unlike that for Cal. 5M4 Series. When repairing the C

1) When the measurement is
made, the IC is still in the
quick start mode. (When the
current consumption
m
easures about 200µA, it is
likely that the IC is in the quick
start mode.)
2) The load applied on the
gear train, etc. has increased,
and the driving pulse to
compensate it has been
generated.
1) After connecting the tester, move
the O
SCILLATING WEIGHT more
quickly for a longer period of time,
and then, make the measurement
again.
2) If the current consumption for
the C
IRCUIT BLOCK alone is within
the standard value range, overhaul
and clean the movement parts, and
then, make the measurement again.
The current consumption for
the C
IRCUIT BLOCK alone
exceeds the standard value.
1) The light from outside the
movement is affecting the
measurement.
2) When the measurement is
made, the IC is still in the
quick start mode. (When the
current consumption
m
easures about 200µA, it is
likely that the IC is in the quick
start mode.)
3) The IC is out of order.
1) Shut out the light, and make the
measurement again.
2) Switch the IC to the normal
mode, and make the measurement
again.
3) Replace the C
IRCUIT BLOCK.
