■ 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.

✽

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.

✶

After swinging the watch, check that the second hand is moving

at one-second intervals.

IF THE SECOND HAND STARTS MOVING AT TWO-

SECOND INTERVALS

(ENERGY DEPLETION FOREWARNING FUNCTION)

● When the second hand starts moving at two-second intervals whether it is worn

or left untouched, the watch may run down within approximately 12 hours.

● When the watch wakes up from power save mode while it is running on extremely

low electrical power, the second hand starts moving at two-second intervals.

● In such a case, swing the watch from side to side to sufficiently charge the KINETIC

E.S.U. (refer to “HOW TO CHARGE THE WATCH” on page 19), and then reset the

time and calendar.
