The A1, the top-of-the-line model in the Golf Watch series, has been reborn as the A1-II with even more features. Black color that matches any style. Retail price: 41,250 yen (tax included) I was recommended golf by a friend and bought it, but I ended up storing it unused. Since I don't seem to have a chance to use it, I'm putting it up for sale. Set includes the main unit, charging cable, and box. Manual is also included. The A1-II is a high-performance, high-function golf watch befitting its "top-of-the-line" status, with features such as undulation display, elevation difference, and estimated distance display* added to the previous model's 1m position accuracy and all-in-one screen. In addition, auto shot count and swing check have been added as additional features.
