Everything you need to know about the new Samsung Gear S3 Classic and Gear S3 Frontier, including the Gear S3 UK release date, UK price, specification and new features. Also see: Samsung Gear S2 review.

Samsung has unveiled its Gear S3 smartwatch in two versions: Classic and the more masculine Frontier. The new watches join the older Gear S2 in the line-up rather than replacing it. These are larger devices with 1.3in circular screens and 46mm casings, and as before there's a rotating bezel. RAM has been ramped up, as has battery capacity, with the new watches expected to last three- to four days depending on your usage. Both are IP68 waterproof, while the Frontier also fits the MIL-STD 810G spec and has optional LTE. Samsung Pay is properly implemented in both watches. Read on for full details.

Samsung Gear S3 new features and specifications

Both Classic and Frontier are circular smartwatches with 1.3in (360x360, 278ppi) Gorilla Glass SR+-protected AMOLED displays, 22mm straps and the rotating bezel seen in the Gear S2. They are pretty tough, with IP68-rated dust- and waterproof protection, though the Frontier is designed to be the more rugged of the two. There is some difference in weight, but both the 62g Frontier and 57g Classic measure 46x49x12.9mm.

The Gear S3 runs Tizen 2.3.2 on 768MB of RAM and 4GB of storage, and both Classic and Frontier support Bluetooth 4.2, 802.11b/g/n Wi-Fi, NFC, MST, GPS and GLONASS. Only the Frontier comes with optional LTE.

There's a 380mAh battery, which charges wirelessly, plus an array of sensors including accelerometer, gyro, barometer, HRM and ambient light.
