This multi-screen smartwatch is called the 'Doppio' and it was designed by Teddy Seyed, Xing-Dong Yang and Daniel Vogel. The watch has two screens and it is expected that this will set set a new precedent for future smartwatches.
The most interesting concept of the Doppio multi-screen smartwatch is that the two screens can be arranged and re-arranged for the user's convenience as well as the operational functioning of the watch. Screens can be stacked and rotated to switch from the clock to the music control and they can even be placed side-by-side in order to make the smartphone appear as one large screen.
One of the screens of this watch is attached to the band and the other is attached via magnet, meaning it can be arranged in whichever way is needed by the user, or even left at home.
