It was launched at the Berlin trade show Thursday, reported Xinhua.
The Galaxy Gear smart watch, which will be on display at the IFA consumer electronics fair in Berlin for six days to Sep 11, will be worn on the wrist to serve as a companion device to Samsung's newest version of phablet Galaxy Note 3, the company said in an e-mailed statement.
The voice-controlled smart watch will allow users to track hands-free call and messages. Samsung said that a user leaving the grocery store whose hands are full with shopping bags, could still make a call by speaking into the Galaxy Gear without touching the screen.
The Galaxy Gear with a 1.63-inch Super AMOLED display has a 1.9 megapixel built-in camera that allows users to shoot videos and take pictures with the slightest gesture and transmit them via Bluetooth to other mobile devices such as the Galaxy Note 3.
The latest version of phablet, or a hybrid of smartphone and tablet PC, enhanced hardware features. The screen size of the Galaxy Note 3 rose from its predecessor's 5.3 inches to 5.7 inches, but it became slimmer and lighter with 8.3mm in thickness and 168 grams in weight.
The device is powered by both Quad-Core processor running at 2.3 GHz and Octa-Core processor at 1.9 GHz. It has dual cameras with a 13 megapixel rear camera and a 2 megapixel front one.
