The most convenient solar-powered model! Black and orange layered belt! The beauty of the metallic orange index! It's solar-powered, but it doesn't have radio wave reception. Purchased new at a certain mass retailer several years ago, but it's unused. However, since the instruction manual and box are missing, I'll list it as "Like New." You can find the instruction manual on the Casio website by specifying Module No. 5445, which is engraved on the back cover. There is no aging deterioration, it's an extremely beautiful item! 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!
