Low-power smart watch that records heart rate, activity levels, and sleep cycles. Amazon exclusive. I am selling this as junk because it wouldn't turn on even after charging it for a while. It seems to be receiving power (see photo 6). I used the shorter band, so the longer band is unused. - Model Name: Smartwatch-H2 - Functions: Records heart rate, activity levels, and sleep cycles - Included: Instruction manual, replacement band, charging cable - Color: Black - Special Features: Low-power smart watch Thank you for looking.
