I believe this is a GARMIN ForeAthlete 735XTJ. I bought it at a flea market for 100 yen. I don't know if it works because there's no charger. Please understand that this is a used item and its functionality is unconfirmed before purchasing. The band is broken. A glass film was applied to the LCD screen, and only the film was cracked. After removing it, the screen was incredibly clean.
