The ClockONE features a simple, elegant design comprising four large digits reminiscent of a digital wristwatch. It's a whopping one meter wide (39 inches) and 35 cm tall (14 inches) but only 4 mm thick, which is about the same as a piece of laminated paper. It also only weighs 3.3 lb (1.5 kg), despite its size.
A magnetic wall-mounting system means the ClockONE is easy to fit and can be adjusted simply by tilting, with no spirit level required. It can also be mounted on top of a bookcase or wall unit, though with this price tag you won't want to risk it falling over and getting damaged.
The E-Ink display, which can be set to show 12- or 24-hour clocks, requires very little power. This means that despite its size, the Twelve24 ClockONE can reportedly run on a single CR2450 button battery for a whole year. The whole thing is made from milled aluminum with beveled edges, giving it the look and feel of a MacBook Air.
The Twelve24 ClockONE is expected to go on sale in September, with an RRP of US$499. Interested parties can sign up to be informed when the presale launches, with an "exclusive discount" offered as a sweetener.
