OK...I have the Garmin Vivofit II. Counts steps, gives me an audio warning if I sit for more than an hour...gives me the time, date/ month, sleep function, heart rate if I use my chest band, times, calories and automatically raise my step goal the more I walk. It also has a back light...and the batteries last a year. I find it works well and is waterproof.....So it has replaced my regular wrist watch...be aware the only way to change the time is to sych it will your computer....
