    My bf loves this watch. He uses it to monitor his physical activity and gets missed call, email, and text notifications.

  • Picture not correct but great watch

    The picture under the Black model actually has the silver bezel not the stainless steal one. If you want the stainless steal bezel version make sure you order the slate gray one. I had to send it back and then I ordered the slate gray one. A pain but HSN did pay for the return. Watch itself is pretty awesome. I love the look and the info it gives you is awesome. And it has maps and Spotify. Yeah!!
