Introduced at CES on Jan. 7, ClockONE by Twelve24 is an ultra-thin, meter-long clock that uses an E Ink electronic paper display to telegraph the time. Twelve24's founder, Andy Mitchelides, says the clock weighs less than four pounds and runs for a year on a single coin-cell battery. Buttons on the colon serve as intuitive controls, and the clock can be hung using a simple magnetic mounting system. ClockONE is expected to start shipping in September 2014 with a suggested retail price of $499. Photo courtesy of Twelve24.
