The Mutewatch will never reveal its true nature while you are not paying attention and just keep on being a cool bracelet on your wrist. But its white face is actually a secret screen that springs to life at your touch.
You can chose between a clock and a timer or set alarm. Since the accessory is called the Mutewatch, the alarm does not buzz but vibrates, which has a point.
To be preordered at the price of $260.
