The Gear S2 is radically different from any other wearable Samsung has put out. There is, of course, the obvious fact that it is the first to utilize a round form-factor, but that is just the tip of the iceberg. The new Gear is yet another radical development in Samsungs wearable family that has been frantically moving towards and then away from standardization and the Android Wear OS.
While still relying on the custom Tizen platform, the Gear S2 now looks to be more in-line with todays smartwatch trends, as set by Google and Apple. Samsung might have finally found a proper course of development to stay in tune with the general flow, while still working on its own vision and delivering a fresh and alternative, yet somehow familiar experience.
