A. BEFORE USING
This watch is not powered by a conventional battery, but is powered by converting light
to electrical energy.
Once fully charged, the watch will continue to run for approximately 6 months without
additional charging. We do recommend exposing your watch to light every day to
ensure optimum performance. Always be sure to recharge the watch before it stops.
Your watch features an Overcharge Prevention Function so there is no need to worry
about overcharging your watch.
A special energy storage cell is used to store electrical energy. This special cell does not
require replacement and is a clean energy unit that does not use any toxic substances.
Before using, be sure to fully charge your watch by exposing it to light.
(See “F. Time required for charging”, for charge time reference)

C. FUNCTIONS OF ECO-DRIVE WATCH
Ifthechargebecomesinsufcient,awarningfunctionwilloperateandthedisplay
changes, as below.

The second hand changes to a two second
interval movement to indicate insufcient recharging.
Eveninsuchacase,thewatchkeepscorrecttime,butabout
4 days after the two second interval movement begins, the
watch will stop.
Afterexposingthewatchtolight,rechargingtakesplaceand
the watch returns to one second interval movement.

■Quick Start Function
The watch will stop if it is completely discharged.
It will begin to operate soon after it is exposed to light.
(However,thetimetostartmayvaryaccordingtothebrightnessofthelight.)
■Overcharge Prevention Function
You can recharge your watch without worry.
Once the special energy storage cell is fully charged, the overcharge prevention
function comes into operation and prevents over-charging of the energy storage cell.

D. CARE AND HANDLING DURING CHARGING
■Notes on Use
To maintain optimal performance, be sure to expose your watch to light regularly.
Please note that if you wear long sleeves, your watch may be hidden from light and
mayresultininsufcientcharging.Assuch,additionalexposuretolightmaybe
necessary.
• Whenyoutakeyourwatchoff,besuretoplaceitinasbrightanareaaspossible.
■Notes on recharging
• Avoidrechargingyourwatchinareasofhightemperatures(overabout60°C/
140°F),otherwisethesensitivecomponentsofthewatchmaybecomedamaged.
(e.g.)Incandescentlightsgenerateheatsufcienttodamageyourwatch.Besure
tokeepthewatchatleast50cm(20inches)awayfromthebulbsonodamage
occurs.WedonotrecommendtheuseofHalogenbulbsforrecharging.
 Neverplaceyourwatchonthedashboardorreardeckofavehicleastheheat
generated in these areas can damage your watch.

E. ABOUT THE ENERGY STRAGE CELL
Unlike ordinary watches, the special energy storage cell used in your watch does
not need regular replacement. This is a clean energy cell that will last the life of the
watch.
CAUTION:
The energy cell should last the life of the watch. Never allow anyone other than an
AuthorizedServiceCentertoreplacethiscell.Themovementisdesignedtooperate
with only the original energy storage cell. If an alternate cell is installed, such as a
conventional battery, the battery may become overcharged resulting in damage to the
movementand/orburstingofthecell,whichcouldcauseinjurytotheuser.
