I think this was the cheapest watch which was very good and looks very good but slightly old model but it has many other features like antilost, pedometer and it also have a very good battery life which was lasting for 5 hrs after continuous use and the watch was very easy to use and the I use to say one thing was it was very good with bluetooth 3.0 and some versions having 4.0. and my experience with this watch was very good andvery good and the look of the watch was good but not best and the battery life as I say it was very good and I can be used for voice calling with loudspeaker and the voice clarity was very good and one more thing when I opened the box I only got a usb manual and smart watch thats it. and I finally say you guys this is the watch which is valuable price for 699- when I bought it in amazon it was 599-, now 650-, etc, . and you can watch the video for more clarity.
