This watch is powered by Citizen's unique Eco-Drive, which absorbs sunlight and any artificial light through the crystal and dial to recharge the watch continuously. With regular exposure to light, the Eco-Drive continuously recharges itself for a lifetime of use. This watch's Eco-Drive provides a 270-day power reserve. It also has a perpetual calendar that automatically adjusts for odd and even months and leap years through 2100. It's matched with a silver stainless steel bracelet band that's joined by a deployment-clasp-with-push-button. Other features include a non-reflective, scratch resistant mineral crystal and two alarms to keep you on time for appointments.
