Samsung has launched the Gear 2 smartwatches on Tizen operating system, just ahead of its Unpacked event at the Mobile World Congress where it is expected to announce its flagship phone, the Galaxy S5.

The Gear 2 will be available in two variants, namely the Gear 2 and Gear 2 Neo, an economy version. Samsung has dropped the Galaxy branding as the new smartwatch does not run Android. Instead, it is powered by Tizen, the Linux based operating system developed under the leadership of Samsung and Intel. The Gear 2 is one of the first commercially available Tizen devices.

Just like the Galaxy Gear, the Gear 2 also sports a 1.63-inch Super AMOLED display(320 X 320p), and is powered by a 1GHz dual-core processor and 512MB RAM. It has 4GB internal storage and features Accelerometer, Gyroscope and heart rate sensors. The Galaxy Gear did not have a heart rate sensor. It also features an IrLED port allowing it to be used as a universal remote control.
 
The Gear 2 comes with a 2 megapixels camera. The Gear 2 Neo does not come with a camera. The Gear 2 Neo is made of plastic while the Gear 2 has a metal face. Both of the variants of the Gear 2 are water and dust resistant. The watch has the ability to store and play music without being connected to a smartphone.

Samsung says the Gear 2 and Gear 2 Neo are compatible with more than "dozens of Samsung Galaxy smartphones at launch," suggesting wider compatibility compared to the Galaxy Gear which was compatible with a handful of high-end Samsung smartphones.

The Gear 2 will be available in Charcoal Black, Gold Brown and Wild Orange colours while the Gear 2 Neo will be available in Charcoal Black, Mocha Grey and Wild Orange colours. It will be available around the world starting April though Samsung has not revealed pricing information.
