[General Reference for Charging Times]

Wear the watch on the wrist for at least 5 hours per day to ensure one day’s

worth of charging at the time of 1-second interval movement. If the watch stops

due to insufficient charge, full charge using the 1-second interval movement will

take about 50 days provided that the watch is worn for 8 hours per day. However,

make sure to attach the watch to the wrist in the correct manner, as the way the

watch is attached will greatly affect the time required for charging. It is recom-

mended to wear the watch daily to store an ample amount of electrical energy

and increase the amount of charge retained by the watch.

[Hints for Effective Power Generation]

•Wear the watch so that the back cover is firmly against your wrist.

•Wear the watch so that heat is released from the watch surface.

• Do not allow the watch to be covered up with clothing (sleeves, gloves, winter

gear, etc.).

•Try to wear the watch for long periods of time.

• Allowing air to blow over the upper surface of the watch while wearing it to

lower the surface temperature makes it easier for the watch to generate power.

CAUTION

[Precautions During Power Generation]

Warming the entire watch dissipates the temperature difference between the

back cover and watch surface, thereby preventing power from being generated.

• Do not warm the surface of the watch by touching with your hand.

• Do not warm the watch with a heating or cooking appliance.

• Do not attempt to warm the watch with an open flame from a gas range, lighter

or other heating device.

• Do not attempt to warm the watch with hot air from a hair dryer or other appli-

ance.

• Do not warm the watch surface with direct sunlight.

• Leaving the watch in locations of high temperature may cause deterioration of

the thermoelectric generation function.

• Do not leave the watch where it becomes high temperature [60˚C (140˚F) or

higher] like on an automobile dashboard.

CAUTION

[Don’t Open the Back Cover of the Watch Unnecessarily]

Never open the back cover of the watch. This may prevent the watch from charg-

ing, cause it to stop running or result in defective water resistance.
