This limited-edition model was very popular and sold out immediately. It's no longer available in stores, making it extremely rare. I've used it about 5 times, but I'm selling it because I don't use it often. I look forward to your purchase. This model features a square case and a refreshing dial color, giving it a classic look. The base model is the popular AQ-230, which combines a square face with an analog clock and a digital display. It combines a retro, simple analog watch with a digital window that displays convenient functions. It's a design that's easy to match with both formal and casual styles.
