    This review is about the colour: Black

    The watch is excellent in terms of quality and functionality, I don't know why someone writes about the time being wrong, probably their app is sending wrong data to the watch. So, no problem for me, everything is perfect, never wrong anywhere. Sturdy metal construction, beautiful and very good strap. I am extremely satisfied.

    This review is about the colour: Black

    The job of every watch is to show the time; this one, if it is not permanently connected to the phone, shows whatever. All the other functions are good, but if it doesn't show the time correctly, the main use is lost.
