I bought the smart watch for a comparison with the same type, but two years older, and this one seems more accurate (pretty big differences between what this one displays compared with the other one while wearing them in the same time ), with an interesting design for the strap, without hanging after my swimming, like the old one does. It's a straight strap instead of curve one for the old type, that's really annoying me while charging. Neat look and bright display. it was easy to connect to my app and now I have a second new smart watch, but and I wanna compare the two new ones.
