The AUTOMATIC POWER GENERATOR

Arm movement is the energy source which sets the oscillating weight in motion. This,
in turn, causes the rotor to spin even faster than an F1 racing car engine. The result is
an electric current which is produced by the coil. This is stored by the capacitor, which
supplies the circuit block with power to drive the watch as needed.

EL GENERADOR AUTOMATICO DE ENERGIA

El movimiento del brazo es la fuente de energía que pone el peso oscilador en
movimiento. Este, a su vez, hace que el rotor gire aun más rápidamente que un motor
de un coche de carreras F1. El resultado es una corriente eléctrica producida por la
bobina. Esta se almacena mediante el condensador, el cual suministra energía al
bloque de circuito para excitar el reloj como sea necesario.

SEIKO KINETIC

®

The SEIKO KINETIC® Cal. 3M22/4M21/5M42/5M43 is an analogue watch featuring an
Automatic Power Generator newly developed by SEIKO. It generates the electrical
energy to power the watch, utilizing the movement of the arm, and stores it in a
capacitor. Therefore, the watch does not use a battery. The watch is also equipped
with a power reserve indicator and an energy depletion forewarning function so that
its constant operation can be assured.

English

■ CAPACITOR

The watch is provided with a capacitor to store the electrical energy generated by the
Automatic Power Generator.
Cal. 3M22/4M21 : When the watch is fully charged, the watch keeps operating for

more than 3 days.

Cal. 5M42/5M43 : When the capacitor is fully charged, the watch keeps operating for

more than 7 days.

■ POWER RESERVE INDICATOR

The current power reserve of the capacitor is indicated by the second hand at the press
of a button.

■ ENERGY DEPLETION FOREWARNING FUNCTION

When the energy stored in the capacitor is reduced to an extremely low level, the second
hand starts moving at two-second intervals to indicate that the capacitor needs
recharging by swinging the watch from side to side.

■ INSTANT-START FUNCTION

Even when the watch completely stops operating, swinging it several times can start
the hands moving. For details, see page 20.

■ ROTATING BEZEL

Up to 60 minutes of elapsed time can be shown.

HOW TO CHARGE AND START THE WATCH

When using the watch for the first time after it is purchased, be sure to charge the
capacitor sufficiently by swinging the watch from side to side, and then put it on.

1. Swing the watch from side to side rhythmically at a rate of twice a second in the same
manner as you would swing a mechanical automatic winding watch.

2. After the watch is swung about 100 times, the second hand starts moving at one­second intervals.
* There will be about 3 hours (Cal. 3M22/4M21) / 6 hours (Cal. 5M42/5M43) of power

reserve available.

3. Swing the watch further about 400 times (Cal. 3M22/4M21) / 300 to 400 times (Cal.
5M42/5M43).

13

English

* There will be about 1 day (Cal. 3M22/4M21) / 2 days (Cal. 5M42/5M43) of power

available.

* It is not necessary to charge the capacitor fully before you wear the watch. While

the watch is on your arm, the Automatic Power Generator will ensure constant
operation.

4. Set the time and calendar, and put on the watch.
* We recommend that the watch be worn daily for at least 10 hours.
* Even if the watch is worn on your arm, it will not be charged while your arm is not

in motion.

Notes:

1. To charge the capacitor efficiently, swing the watch from side to side, making an arc
of about 20 cm.

2. No additional benefit is obtained by swinging the watch more quickly or with greater
vigor.

3. When the watch is swung, the oscillating weight in the generating system rotates to
drive the mechanism. As it rotates, it gives out sound, which is not a malfunction.

4. Provided with an instant-start function, the watch may start operating after it is
swung several times. For details, see “INSTANT-START FUNCTION” on page 20.

POWER RESERVE INDICATOR

The current power reserve of the capacitor can be checked instantly by using the power
reserve indicator function.

1. Press the button at the 2 o’clock position. The second hand moves quickly and stops.

2. The number of seconds that the second hand advances indicates the power reserve
in the capacitor. (See the table on the next page)

3. Please note that after the power reserve is checked, the second hand will resume
normal movement again after the indicated 5, 10, 20 or 30 seconds have elapsed.

4. If the watch needs recharging, swing it sufficiently.

✩

The power reserve indicator provides a general guideline of the duration within
which the watch keeps operating without needing to be charged. Actual power
reserve may differ slightly from the amounts shown in the table.

When the second hand advances 30 seconds at a press of the button, the capacitor is
fully charged and the watch will keep operating for more than 3 days (Cal. 3M22/

4M21) / 7 days (Cal. 5M42/5M43). It can continue operating for a maximum of 7 days
(Cal. 3M22) / 4 days (4M21) / 14 days (Cal. 5M42/5M43) without recharging the

capacitor.

19

English

Notes:

1. To allow easy reading of the second hand, we recommend that the button be pressed
when the second hand is at the 12 o’clock position. When the second hand points
to “LO”, the capacitor has a power reserve of between 1 and 2 days (Cal. 3M22/4M21)
/ 2 and 4 days (Cal. 5M42/5M43).

2. You can immediately press the button again to recheck the power reserve one more
time. To do so a third time, however, wait until the second hand resumes normal
movement before pressing the button again.

3. When the second hand moves at two-second intervals, the power reserve is very low
and the indicator does not function. See the next section, which explains the Energy
Depletion Forewarning Function.

4. Immediately after the watch is swung to charge the capacitor, the second hand may
not properly indicate the power reserve. Please check after putting the watch on
your wrist.

5. Precaution on see-through case-back models:
If your watch has a glass case back, do not expose the case back to strong light such
as direct sunlight or an incandescent light at close range, as this may temporarily
increase the power consumption of the watch circuit, thus reducing the power
reserve in the capacitor.
This condition, however, will be corrected when the case back is turned away from
the light.

20

English

ENERGY DEPLETION FOREWARNING FUNCTION

When the energy stored in the capacitor is reduced to an extremely low level, the second
hand starts moving at two-second intervals instead of the normal one-second intervals,
indicating that the watch needs recharging and will run down in approximately 3 hours
(Cal. 3M22/4M21) / 6 hours (Cal. 5M42/5M43).
If you find the second hand moving at two-second intervals, therefore, be sure to swing
the watch from side to side to charge the capacitor sufficiently before using it.

Note: The watch remains accurate even while the second hand is moving at two

second intervals.

INSTANT-START FUNCTION

This function is very useful when a watch has been stopped for a long time and you
need to get it started quickly with only a few swings.
This function is available as long as:

1) the watch previously had more than 2 days (Cal. 3M22/4M21) / 4 days (Cal.
5M42/5M43) of power reserve before it stopped.

2) it has been left untouched for 1 to 4 weeks.

21

English

* After you swing the watch several times and note that the hands are moving,

be sure to put it on your wrist so that it will be charged further until the second
hand is moving at one-second intervals.

Note: If the second hand continues moving at two-second intervals after the

watch is put on your wrist, swing it from side to side until the second
hand starts moving at one-second intervals, and then, put in on your
wrist.

REMARKS ON THE RESERVE POWER OF THE CAPACITOR

• As the watch is powered by the electrical energy stored in the capacitor, it uses no
battery.

• Even while the second hand is stopped by pulling out the crown all the way, current
continues being consumed by the built-in IC. Please note, therefore, that, while the
watch is not in use, pulling out the crown all the way will not save the energy stored
in the capacitor.
