Legendary model! GA-400 series! Super colorful design with a yellow base! Excellent functional beauty with an analog-digital layout! ❗️Battery is dead!❗️ ❗️It should work with a battery replacement, but there is no guarantee!❗️ Please purchase only if you understand this! Purchased new at a certain mass retailer several years ago, but it's unused. However, the instruction manual and box are missing, so it's listed as "Like New"! You can find the instruction manual on the Casio website by specifying Module No. 5398, which is engraved on the back cover! A very beautiful item with no age-related deterioration! The watch itself will be shipped 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!
