Twelve24 has recently introduced their game-changing ClockONE. The ClockONE utilizes E-ink technology that gives you a high contrast, wide viewing angle. Probably the best thing about the ClockONE is the battery life. Stick in a single button battery, and you’re looking at one whole year, that’s right, 365 days of battery life! Incredible. Currently, the clock is available for pre-order over on their website.
