(Telecompaper) Samsung Electronics has unveiled two new smartwatches running the Tizen operating system, its first devices on the Linux-based OS. The Samsung Gear 2 and Gear 2 Neo come just over six months after its first smartwatch, the Galaxy Gear unveiled in September 2013. The watches again feature a 1.63-inch Amoled screen and choice of five coloured straps, as well as a faster 1.0 GHz dual-core processor. The Neo is the lighter of the two devices, while the Gear 2 comes with a 2.0 megapixel camera, fitted to the body of the device this time rather than the strap. Users can manage incoming calls and messages on the phone from the watch and set response notifications. They can also control other consumer electronics, such as as TVs and set-top boxes, through the WatchON Remote application and IrLED sensor, and manage their fitness routine with applications like a heart rate monitor. The new watches also add a music player with Bluetooth headset. The Samsung Apps store will offer a range of applications based on the Tizen wearable platform. The Samsung Gear 2 and Gear 2 Neo will be available around the world starting from April.
