Gear S: The smartwatch that can make calls without a smartphone

The Gear S has a 2-inch super AMOLED screen and uses a dual core processor running at 1GHz. The smartwatch is powered by a Tizen-based OS.

The 3G, Wi-fi and Bluetooth connectivity enabled device can handle all communication needs of users, including calling, texting, chatting and e-mailing even if not paired with a smartphone.

Gear S comes with multiple sensors - including a heart rate monitor, Gyroscope, Barometer and a UV sensor that warns you when the UV index is too high - and acts as your personal health coach.

With over a thousand apps accessible on the go, the Gear S redefines smart wearable tech. That's not all, S Voice allows users to complete tasks hands free, Samsung says.
