The idea here is to provide people with a digital display watchface on which all of the hands move at the same speed on circular scales with radii differing by factors of sixty.
The red circle and attached hand represent seconds, so that the hand completes one revolution per minute.
The black circle has only a segment visible and its hand moves at the same speed, but represents the passage of minutes.
Similarly, the blue circle and hand represent hours.
As time increases from the left to right hand diagram, so the hands all move clockwise at equal speed and the visible sections of the arcs on which they move are adjusted continuously.
Why would anyone want this? Well it makes the passage of even hours visible (imagine zooming in on the small-scale movement of a conventional hours hand).
