This is a Casio A168WA-5AY. I bought it for 5,000 yen, but I haven't used it much since. I've only used it once or twice, so it's in excellent condition. The wrist size is adjusted to 15.5cm, but you can easily adjust it yourself. Please consider purchasing it, understanding that it is a used item.
