This is an item for sale to organize my collection. It's a Casio G-Shock Tough Solar GW-M5610. This square-type watch is based on the compact and highly wearable DW-5600 model. The GW-M5610 series is a popular model known for its thinness, light weight, and radio-controlled solar power. Radio Wave Reception: With Multi-Band 6, it automatically receives standard radio waves several times a day from 6 stations worldwide: Japan (2 stations), China, North America, the UK, and Germany, correcting the time, so there is almost no time drift. Tough Solar Model: It primarily charges the battery with sunlight, so the frequency of battery replacement is dramatically reduced compared to quartz types. It's a classic model that suits various outfits and is lighter and easier to use than metal models. The secondary battery currently shows "H," and it has been like this for a few days, but the condition of the secondary battery is unknown. Solar charging, radio wave reception, and the backlight all function without problems. While there is some wear and tear on the band, the bezel is relatively clean, and the crystal is scratch-free. Some watches have bands that are about to break or backlights that don't work, so this one is a great value. Accessories: None Operation: Good Movement: Radio-controlled solar Body Color: Black (matte) EL Backlight: Blue-green Operation: Good Scratches/Cracks: None
