Citizen Eco-Drive technology harnesses the power of light and converts it into energy which is stored in a permanent lithium-ion cell. It recharges continuously in any kind of light meaning it will keep on working and with a power reserve which can last from 6 months to 5 years it will keep the correct time even in the dark. And if it does eventually go to sleep if kept in the dark for too long, all you need to do is expose it to light again. With this watch you never have to go to the hassle and expense of changing a battery.
Comes packaged in Citizen Watch Box with Citizen 5 Year Warranty giving you superior protection and peace of mind
