Thank you very much for considering this product! I purchased this product about a year and a half ago from the official Huawei store on Yahoo Shopping. The original strap broke, and I am currently using a metal strap purchased from Amazon. There are no other noticeable scratches on the main body. There were no particular system malfunctions either. Returns are not accepted except for initial defects, so please be sure to contact us with any concerns via comments before purchasing. The HUAWEI WATCH GT 3 SE is a smartwatch that combines stylish design and high functionality. It's ultra-lightweight at 35.6g and offers excellent wearing comfort. It features a battery that lasts up to 14 days and advanced sleep and health monitoring functions. It supports over 100 types of workouts, making it a high-cost-performance watch that is useful for everything from daily life to本格 sports. - Model Name: HUAWEI WATCH GT 3 SE - Brand: HUAWEI - Color: Black - Accessories: With box Thank you for viewing.
