This is a GARMIN FOREATHLETE 645 MUSIC. Retail price: 54,780 yen. I purchased this, but I'm selling it because I no longer use it. You can listen to music by putting music from Spotify on it, and it also has an electronic payment function, so you can put your credit card on the watch. You can also measure your heart rate and do various other things. The only concern is that the backlight doesn't work. Please consider the price, taking into account the scratches and the non-functioning backlight. The box is not included.
