The new Gear models allow you to control other electronic products in your home, such as your TV and set-top box, as well as acting as a standalone music player that can allow you to access your music even if you do not have your smartphone on you.
Furthermore, the watches offer personal fitness coaching, including a customized fitness routine and a heart rate monitor. It's part of a growing craze for fitness-related wearable tech, such as Nike's Fuelband and Fitbit.
