A new smartwatch has been launched by Samsung, which is capable of making calls and receiving data without having a connection to a smartphone

One would assume that such a watch would also allow for third-party apps, as Samsung's prior watches have, allowing it to do much more.
The device would essentially put the key capabilities of a smartphone into a watch, requiring a SIM card and likely a data and voice plan too.
Samsung's been more than happy to experiment with the shape of smartphones, often to ridiculous results, and it sounds as though this watch will be just another extension of that.
