This Citizen Nighthawk is powered not by an ordinary battery, but by converting photo energy to electrical energy.  A secondary battery is used in this watch to store electrical energy. This secondary battery is a clean energy battery which doesn’t use any toxic substances such as mercury. Once fully charged, the watch will continue to run for about 6 months without further charging.  This watch has a Insufficient Charge Warning Function i.e., the second hand changes to a two second interval movement to indicate insufficient recharging. Even in such a case, the watch keeps correct time, but about 3 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.

This Citizen Eco Drive watch allows the hour hand only to be corrected independently without stopping the watch. It can be used as a dual time watch by setting the 24 hour hand and hour hand to different times. After correcting the time, the hour hand is used to indicate the “local time hours”.  Another feature of this watch is Quick Start Function. The watch will stop if it is completely discharged. It will begin to operate soon after it is exposed to light. It also has Time Setting Warning Function. i.e., if the watch stops, subsequent exposure to light allows the Quick Start Function to start again, and the second hand moves with a hitch to indicate that the time incorrect. In this case, quickly recharge the watch and reset the time. Otherwise, the hitch movement will continue.
