From the minds at the Korean firm, Elevenplus, comes this brilliant, cylinder clock, featuring a unique rolling mechanism that allows you to switch between twenty-four time zones in one swift roll. Roll the clock to meet the timezone of choice, and simply let go to allow the clock to roll back and set the time. The zones are displayed around the diameter, pairing up major cities with twelve hour differences. These handy little guys are also quite pleasing to the eye, available in three colors, modern gray, midnight blue, and orange passion. Have a look at the video to see the clock in action.
