Smartwatch with high-precision health management features - Brand: amazfit - Model Name: GTR 4 - Accessories: 2 charging cables, box, instruction manual - Color: Black I believe I used it for about a year and a half. I used a screen protector, so the screen is in good condition. It will be shipped after initialization. Since there are two charging cables, you can use one at home and one at the office, etc. Thank you for looking.
