HOW TO CHARGE THE WATCH

1.Swing the watch from side to side rhythmically at a rate of twice a second as shown in the illustration below.

This movement will recharge the watch to start moving at the normal one-second intervals from the two-second interval movement. If you find the second hand moving at two-second intervals after swinging the watch, swing it further until the second hand moves at the normal one-second intervals.

After swinging the watch, check that the second hand is moving at one-second intervals.

To charge the KINETIC E.S.U. efficiently, swing the watch from side to side rhythmically at a rate of twice a second, making an arc of about 20 cm.

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

When the electrical energy stored in the KINETIC E.S.U. is completely depleted after the watch is left untouched for a long time, the watch requires at least 450 swings to generate power to resume the normal operational movement.

2.It is recommended that the watch be swung further until it can reserve enough power to run the watch for approximately one day.

As a guideline, 200 swings will generate the power to run the watch for approxi- mately one day.

POWER RESERVE GUIDELINES FOR THE KINETIC E.S.U.

As a general guideline, if you wear the watch every day for 12 hours over a period of a week,

English

Wearing the watch continuously for 12 hours will accumulate power to run the

 

 

watch for approximately one and a half additional days.

 

 

the power to run the watch for approximately ten days will be additionally secured. If the

 

 

watch enters the power save mode, this amount of energy will keep the watch running for

 

 

approximately one month and a half.

 

POWER SOURCE (KINETIC E.S.U.)

This watch requires no periodic battery replacement as it is powered by the exclusive secondary battery, which is completely different from conventional batteries for watches. This exclusive secondary battery is an environmentally friendly, clean energy storage device.

CAUTION

Never install a silver oxide battery for conventional watches in place of the KINETIC E.S.U. , which can generate heat that can cause bursting or ignition.
