Just as predicted, Samsung also announced their Gear S Smartwatch. The defining characteristic of the Gear S is that it has its own nano-SIM card and 3G connection so it can be used as a replacement for your smartphone. After an initial setup through a Samsung smart phone, the Gear S can operate exclusively as your smartphone. You can also text and use apps. It uses the Tizen OS for all of its functionality and has a 2-inch curved display. It also includes several health sensors to be used as a fitness device.
