❗️Battery is dead!❗️ ❗️It should work with a battery replacement, but there's no guarantee!❗️ ❗️I purchased the three colors released at the same time and did a small custom modification by mixing the bands!❗️ I bought this new at a certain mass retailer several years ago and it's unused, but because I've lost the instruction manual and box, I'm listing it as "Like New"! You can find the instruction manual on the Casio website by specifying Module No. 5590, which is engraved on the back cover! There is no aging deterioration, it's an extremely beautiful item! I will ship the main unit only via Yu-Packet Post, and changes are not possible! Even during transaction communication, I will unfortunately prioritize the first person to purchase! Thank you for your understanding... Shipping may take a few days due to my circumstances! Sorry! Usually, I will ship within 2-3 days! Thank you!
