Popular large three-eyed digital watch! Calm all-black design! Blue that stands out on the dial! Purchased new at a certain mass retailer several 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 the module number 3427 engraved on the back cover! The battery life on the specifications is 7 years! Since the light and alarm are also unused, I think it will still work for a long time, but I cannot guarantee the battery. 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! I'm sorry! Usually, I will ship within 2-3 days! Thank you!
