I purchased this several years ago for the retail price of 23,000 yen. It's working without any problems. Color: White. Solar-powered, radio-controlled watch. Running cost is zero. It's a used item, so there is a feeling of use. I think you can use it for a longer period if you replace the belt with your favorite one after purchase. I'm selling it at a bargain price because there's no need to replace the battery. Belt adjustment parts included. The instruction manual is missing.
