POWER SOURCE (RECHARGEABLE BATTERY)
POWER RESERVE GUIDELINES FOR THE
RECHARGEABLE BATTERY
● Wearing the watch continuously for 12 hours will accumulate power to run the
watch for approximately one and a half additional days.
✽
As a general guideline, if you wear the watch every day for 12 hours over a period of a week,
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.
✽
To charge the rechargeable battery 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 rechargeable battery 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.
NOTES ON OVERHAUL
The watch is a precision device. If the parts run short of oil or get worn out, the watch
may stop its operation or lose time. We recommend you have the watch overhauled
periodically to keep it running accurately.
This watch requires no periodic battery replacement as it is powered by the exclusive
rechargeable battery, which is completely different from conventional batteries for watches.
This exclusive rechargeable battery is an environmentally friendly, clean energy storage
device.
CAUTION
Never install a silver oxide battery for conventional watches in place of the
rechargeable battery, which can generate heat that can cause bursting or
ignition.
