The round-faced Gear S2 is fitted with a 1.2-inch (30 millimetre) circular screen and allows for mobile payment and remote control over home appliances as well as common phone calls and text messaging features, according to a company statement.
    
Samsung is hoping the new watch will compete with similar Apple products, after the US company became the top provider of wearable devices worldwide only months after the Apple Watch was unveiled in April.

Samsung has released a series of smartwatches since 2013. However, most of the models have been met with lukewarm responses from consumers.
    
Apple has dominated the wearable device sector, shipping about four million smartwatches globally in the second quarter -- about 75 per cent of the overall market – market researcher Strategy Analytics estimated in July.
