The Gear Fit is listed at Rs 15,450, while Gear 2 and Gear 2 Neo are listed at Rs 21,550 and Rs 15,450 respectively.

At a low-key launch event in Barcelona, Samsung also unveiled the Gear 2 smartwatch, which runs on the Tizen operating system rather than Google's Android software, and a stripped-down version called Gear 2 Neo, which doesn't have a camera.

The devices can monitor the wearer's heart rate, a function used in increasingly popular health and fitness apps, or individual programmes.

The Samsung Gear Fit, also targeting the fitness sector, has a heart rate monitor. The Gear Fit has a curved touch-sensitive screen and its features include a pedometer.
