Samsung Gear S2 Smartwatch: Stay connected even when you're away from your phone with this smartwatch, which receives texts, e-mails and notifications and features S Health and Nike+ Running integration to track your health and fitness. The 1.2" Super AMOLED touch screen makes it easy to navigate apps and Web pages.
With this model you cannot talk through the watch like the previous models. It's a shame Samsung removed such a desirable feature. I returned the watch the same day.
