Google's Motorola division has formally launched its highly anticipated circular smartwatch, the Moto 360.
The Moto 360 features a 1.5in (3.8cm) LCD touchscreen encircled by a thin metal band.
The waterproof device is powered by Google's new Android Wear operating system, which is designed for small screens.
The BBC's North America Technology correspondent Richard Taylor has been trying out the device.
