Samsung Gear S2 review: seventh time lucky for Korean firm's smartwatch

Latest Android-compatible Tizen watch is comfortable to wear, has a crisp round screen and great rotating bezel, making it Samsung's best by a mile

Samsung has finally cracked the smartwatch with its seventh design: a round watch compatible with almost all Android smartphones and with a rotating bezel that's not just for show.

The world's biggest smartphone manufacturer has quite a lot of experience making smartwatches. Its first was launched in 2013, but since then the South Korean firm has made six different models, though none of them have quite got it right.
