【Brand New】 I am selling this because I have no opportunity to use it. It connects stably to your smartphone via Bluetooth 5.3, enabling calls and Alexa voice control. It features a high-definition 1.8-inch screen that allows you to check notifications in real-time. With 100 sports modes and IP68 water resistance, you can also track your exercise with peace of mind. It also has comprehensive health management features and support for women. It's multifunctional, including music control and phone finding, and can be used for up to 15 days with a charge of about 2 hours. Thank you for looking! ☆
