This is the third time I bought this watch. I don't know if blood pressure, heart rate ... is correct. It gives a good indication. For tihis price it offers more then one would expect. I had two problems: first watch: when connected for calls to my smartphone sometimes the watch blocks. Only solution is then wait until the battery is down. second watch: the battery stopped working But once again, it is a beautiful watch, fantastic screen, and a lot of functions that are working well.
Thank you! I received the parcel. The clock is normal.
