One of my favorite rings was the Kinekt Gear Ring, but this concept ring is my new favorite. Now I just hope it becomes a reality. The Ring Clock lines up the hour, minute, and seconds so you can tell what time it is quickly. Genius.
"Ring Clock is a mechanical ring, which displays the current time. It has three rings for displaying the hour, minutes and seconds. The current time is highlighted, and there is an indicator so the wearer can know which way to put it on."
