This is a Citizen Eco-Drive ladies' watch. I purchased it two years ago, but I've only used it two or three times. I believe it's still in good condition. The solar cell built into the watch generates power when it receives light, which drives the watch. There's no need for regular battery changes; you can simply charge it by exposing it to sunlight. - Brand: CITIZEN - Color: Gold I'm also open to price negotiations, so please feel free to comment. Thank you for looking.
