Your new Eco-Drive timepiece is specially powered by proprietary ECO-DRIVE TECHNOLOGY, 

which converts any source of light (natural and artificial) into usable energy. The harnessed energy 

is then stored in a special power reserve to keep your timepiece charged and running properly. 

When fully charged, your Eco-Drive will continue running - even in total darkness- for at least six 

(6) months. Properly maintained, it will never need another battery. 

If you wear your new Citizen Eco-Drive timepiece on a regular basis, recharging will be virtually 

automatic as regular exposure to light will keep your power reserve unending.

Recharge times will vary based on your timepiece and the type of light utilized. Direct sunlight is 

the fastest, most efficient light source for recharging. Recharging information for your basic analog 

timepiece can be found on page 4 of this booklet. For other models, please refer to your specific 

instruction booklet or the technical support section of our web site at www.citizenwatch.com.

If you plan to store your Citizen Eco-Drive in the dark, you should do this for no more than six (6) 

months. After this extended period of time, you should ensure that your timepiece is exposed to 

bright light for the full recharge period as outlined in the recharge guide on page 4 in order to return 

your timepiece to a full charge.

Your Eco-Drive timepiece thrives with regular exposure to light sufficient for charging. 

Some circumstances however may prevent your Eco-Drive timepiece from receiving 

regular exposure to light sufficient for charging. In these circumstances, you may need 

to provide supplemental exposure to light. The chart below outlines general recharging 

requirements for your basic analog Eco-Drive timepiece.

After your basic analog Eco-Drive timepiece is fully charged, it will run for a minimum

of six (6) months without further charging. 

Your Eco-Drive timepiece features an overcharge prevention system. When the recharge-

able cell is fully charged, special circuits engage to prevent it from becoming over-

charged. There is no need to worry about exposing your timepiece to “too much” light.
