The Samsung Gear S2 is, based on the precious 45 minutes I got to spend with it on Wednesday, a remarkable rethink of the Gear line. From first impressions to fiddling with the new buttons, and playing with its signature circular interface and very pleasing rotatable bezel, the Gear S2 (and Classic), shouts quality, design and, thank goodness, attention to how humans might actually wear and use watches (smart or otherwise).
