This is a Casio Wave Ceptor, Multi Band 6, Tough Solar watch. It's an all-black, cool model, but the rechargeable battery is dead. The watch works when exposed to sunlight for a while, so I don't think it's broken. Please consider this if you can replace the rechargeable battery. It's in almost-new condition, but there is one scratch on the top of the glass. This is a junk item, so no claims and no returns. Following Mercari rules, you can buy it immediately on a first-come, first-served basis.
