A round detail of a pictorial or graphic illustration is, divided up into sectors, distributed on a number of discs. These discs are mounted on a movement in place of hands and thus, in each case after slightly more than a full rotation of the second-slowest disc (the minute-hand disc), again reveal a completely visible view of the illustration, in other words after 651/2 minutes. A marking on the discs makes setting and telling the time possible. <IMAGE> |
