I am selling this item to organize my collection. Retail price: 66,000 yen. This is a radio-controlled, solar-powered model. I haven't used it much (worn less than 10 times), so it looks quite clean, but it stopped working after being stored. (It may be due to the depletion of the secondary battery.) Therefore, I would appreciate it if you could purchase it as a junk item. It will be sold at a significantly reduced price, so please consider purchasing it. It will be sold with the box. The wrist size is over 20cm, so please adjust it by removing the links. I am sorry, but returns and claims are not accepted. 【CASIO/G-SHOCK】 GST-B100D-1A9JF G-STEEL G-Steel Tough Solar Bluetooth equipped mobile link/app連携 function Metal bezel Metal band Silver Black Gold ■Specifications, Functions ●Shock-resistant structure ●Tough Solar (solar charging system) ●20-atmosphere water resistance ●Mobile link function (function linkage via BluetoothR communication with compatible mobile phones) ●Dual time (with home time exchange function) ●Stopwatch (1 second, 24-hour counter, with split) Dial color: Black Belt color: Silver Accessories: Box Scratches/Cracks: None Operation: Defective (non-working) GA-100 G-Shock G-Steel No battery replacement needed Tough Solar No battery replacement needed Home appliances Watches Casio/CASIO G-Shock G-SHOCK G SHOCK Shock-resistant structure Shock Resist ANALOG DIGITAL Analog Digital Analog & Digital Model Analog Digital Model Ana-Digi Analog Watch Analog Watch Analog Clock Digital Watch Digital Clock WOMEN Women Skeleton SKELETON Matt MATT Tough Shock Watch Watch Watch Casio Men's Ladies Kids Men Women Unisex Children Boys Girls Popular Stylish Cool Cute Sports Travel Leisure Gift Birthday Birthday Celebration Commuting School Commuting Anniversary Home Appliances
