Citizen Eco-Drive technology never needs a battery; it harnesses the power from any natural or artificial light source and converts it into energy which is stored in an Eco-Drive energy cell. It recharges continuously in any kind of light to run forever.

This watch has a screw-down crown (knob) for setting the time. Screw-down crowns create a stronger seal against the case than a push-and-pull knob, giving the watch a greater water resistance factor. To unscrew the crown, grasp the knob and turn it counter-clockwise (towards you) a number of times until it releases. Then pull or push the crown into position to set the time, date, and other functions. To close the crown, press it against the case while turning in a clockwise direction.

Note: Watch may NOT be returned if security tag is removed
