Samsung's circular Gear S2 smartwatches run Tizen

From PC World: Samsung has made its latest foray into the smartwatch market with the new Gear S2 and Gear S2 Classic, expanding its ever-evolving lineup of wearables.

The watches, announced Monday, have circular screens 1.2 inches in diameter, making them stand out from Samsung’s other wearables, most of which have sported rectangular faces. The interface takes advantage of the round screen, including an app launcher that lets users tap on round targets to switch applications.

The watches have a ring around the face that rotates to control functions, and they have new fitness capabilities, including a 24-hour activity log that users can check to see at a glance how active they’ve been.

The Gear S2 Classic will have a black stainless steel case and a black leather band, while the Gear S2 will come in a dark gray case with a dark gray band or a silver case with a white band. According to Samsung, the watches will run for 2-3 days depending on how people use them. Unlike their predecessor, both the Gear S2 and S2 Classic will be available without a 3G modem, though they will have reduced functionality when not in range of a paired Samsung smartphone.
