A:AnswerI have a 6.75" circumference wrist and the small barely fits me where you're supposed to wear it but the large (husband has it) is too big. The box has a measuring chart on it if you purchase the item in store.
A:AnswerOn average, this takes around an hour to two hours. A full charge generally lasts around 4-5 days depending on usage, less if you are pretty active.
It came with almost a full battery when I got mine, but the first time I charged it was almost the same time as every other time, around an hour to two hours.
A:AnswerThe Charge HR is the best selling unit here at my local Best Buy according to the sales staff. As soon as they come in, they are gone right away. I had to special order mine. Had it shipped to Best buy and got it in 3 days.
A:AnswerIt doesn't exactly have a stopwatch, but if you press and hold the button, it will work as an "exercise" timer that will keep track of how long it has been since you pressed the button. Hope that helps.
A:AnswerNo. It does measure heart rate on a continuous basis. The app produces charts that you can share with your doctor and track your resting heart rate on a day to day hour to hour basis.
