Samsung's Wi-Fi/3G-enabled Gear S smartwatch coming to all major US carriers on Nov. 7

The IP67-certified, dust- and water-proof device measures in at 1.57 x 2.28 x .49 in (39.9 x 58.1 x 12.5 mm) and both the Blue Black and White models weigh 2.32 oz (66 g). As already mentioned, the device also has dedicated Wi-Fi 802.11 b/g/n radio, but also Bluetooth 4.1 Low Energy and A-GPS with GLONASS support. Embedded within the body are also a whole bunch of sensors, including an accelerometer, gyroscope, compass, barometer, along with monitors for UV light and heart rate. With so much hardware packed inside, Samsung didn't have a lot of space leftover to fit in a large battery, so we're looking at a 300 mAh unit, which probably will require charging every night -- at least based on our experience with smartwatches so far.
The Gear S will first launch on AT&T and Sprint on November 7 ($199 w/ 2-year contract or $16/mo. for 24 months, respectively) and, two days later, on T-Mobile ($14.58/mo. for 24 months). Verizon is confirmed to also get the gadget, but is keeping mum for now.
