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.

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.
