This is a beautiful watch but it’s not a very “smart” watch. It keeps time and counts steps but those are only the basic stats I can count on. Blood pressure measurement has not changed once since I set the watch up so I can’t depend on this measurement to be accurate. Sleep data I’m sure isn’t accurate and there is no detail on REM versus deep sleep. Also, 15 minutes into a walk the watch will ask me if I’m walking…my walk is almost over! It doesn’t detect exercise on its own. The watch has a button to press if you want the face to light up to see what time it is but, while sleeping at night, certain arm movements make the face light up like a flashlight in the dark!
So if you’re looking for a nice looking watch that keeps time and counts steps this is it but if you want a watch which gives you accurate data on sleep, blood pressure, etc. you will be disappointed. I am keeping this watch for now because I do like the time and step counting features but will go back to a Fitbit or buy an Apple Watch in the future.
