Popular large, three-eyed digital watch! Eye-catching lime green accents on black! A calm gray face! Purchased new at a certain mass retailer a few years ago, but it's unused. However, the instruction manual and box are missing, so I'm listing it as "like new"! You can find the instruction manual on the Casio website by specifying module No. 3427, which is engraved on the back cover! The battery life listed in the specifications is 7 years! Although several years have passed since the purchase, the light and alarm haven't been used, so I believe it will still function for a while, but I cannot guarantee the battery life! It's a very beautiful item with no aging 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!
