I had a fitbit one for many years and I washed it twice because it clips on my pants. I finally got a charge which is like a watch and I love it! When you flip your wrist, the time will appear. It monitors my calories, miles, sleep and steps but it also notifies me of any phone calls. It connects via Bluetooth and is completely handy. The battery doesn't last as long, of course, because of the Bluetooth but it's been about a week now and it is still going. I love my new charge!
