This is a great watch for me to use, I actually work a lot and don't have time to manage my health, when I use this watch it will always monitor my health including blood pressure, heart rate, sleep etc. There is no major discrepancy between the relevant data and the actual measurement, which is within acceptable limits. In addition to this, there is a sedentary reminder and a water reminder that reminds me to move my body at regular intervals during long working hours, which I like and would recommend to my friends.
