What could a smartwatch do? Generally, smartwatch is a smartphone companion device. It supports notifications, call alerts, message, fitness features, app and other information. And of course, it could tell the time. With the development of smartwatch industry, more and more watches have been released in the market. You may be confused about which one is better, here I want to present the top 5 smartwatch in 2016. 1.Apple watch sport System on a chip: Apple S1, initial operating system, watchOS 1.0 which makes the watch easy to use and quality construction.  8 GB storage means plenty of apps.42 mm display is really big display as a watch. 246mAh battery and only compatible with IOS are the big limitation. But the square frame with black strap is really nice out looking.   2.Samsung Gear S2 The most attractive thing is the rotating bezel and unique circular interface, awesome operation make it easily access your apps and notifications. Super AMOLED screen and wireless charging both are the standout feature. Compatible with most Android smartphones which is also a good feature. Unique rotating bezel and classic modeling makes it the awesome watch.   3.Pebble Time Smartwatch This watch is the most rugged one in  this list. With water resistant to 30 meters and shockproof, you can use in any occasions. 7 days battery life is also the longest battery life in this list. Compatible with Android 4.3 and above,but lack of apps. All in all, Pebble Time is the best square smartwatch.   4.NO.1 D5+ Quad-core MTK
