The device runs on a dual-core processor with 512MB of RAM, powered by a modest 300mAh battery, and features an accelerometer, gyroscope, proximity sensor, compass, heart rate sensor, barometer, and UV light sensor. It is based on a Samsung home-grown wearable Tizen platform. Swiping the watch-face to the left gives you access to Messages, E-mail, Missed calls, Contacts, Apps, data from your smartphone, and basically all functionality at hand. We saw weather and agenda apps too, along with a news reader. There is some pretty advanced functionality built into this smart-watch, and Tizen OS seems to become a pretty adequate alternative to Android Wear as time goes by.
Although it doesn't have the LG G Watch R's incredible looks, the Gear S is an interesting device with a charm of its own. We'd love to tell you more when we get the chance to spend more time with it ticking on our wrists.
