QUICK MOVEMENT OF
SECOND HAND
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.

lHow to discriminate resembled parts
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.

43 GENERATING COIL BLOCK 4002514
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.
