Hardware
The Gear S is similar to older versions of the Samsung Galaxy Gear although it does come with some new additions. The Samsung Gear S has a curved 2.0 inch Super AMOLED screen at 360×480 pixels. It has a Quad Core 1.0 GHz processor (limited at two running cores from factory) and runs the Tizen operating system. As with the Galaxy Gear 2, the Gear S includes 512 MB RAM and 4 GB internal storage as well as a 300 mAh Li-ion battery.

Using a 3G module the watch itself is able to connect to the Internet, make phone calls and send SMSs without needing a phone. It was the first wearable device to include Wi-Fi, Bluetooth and 3G connectivity.
