Final verdict
This issue, Samsung has produced a technically outstanding watch. It is stable, responsive and has the best wearable interface I've come across. The combination of two buttons and a rotating bezel to control it works marvelously. Despite technically being the first of its kind for Samsung, the Gear S2 feels surprisingly accomplished.
The Gear S2 has numerous excellent qualities, but deciding whether it's for you will come down to whether you're happy to use Tizen apps rather than the Google apps you may be more familiar with.
