The Samsung Galaxy Watch is the name of the latest smartwatch from Samsung, finally putting to rest rumors that the wearable was going to be called the Samsung Gear S4 or Samsung Gear Sport 2. 

The Galaxy Watch comes in two different sizes. Although there's nothing official yet, we suspect these sizes to be 42mm and 46mm options. Announced alongside the Samsung Galaxy Note 9, the new watch is set to be on sale nearer the end of August.
