Unused, but radio wave operation has been confirmed. When setting the time via radio waves, the second hand is slightly off, but this is only for those who don't mind. No claims will be accepted. Please refrain from purchasing if you are concerned. The watch is 17,600 yen including tax. It's a Japanese-made watch from the manufacturer Takata Lemnos, with the deuxC logo. Includes a single AA battery. Outer diameter is approximately 28cm. Thank you. #Halloween on Mercari
