The performance of these "eternal" hours you can watch endlessly

Still, there is some charm in the old-fashioned "analog" hours, especially if you belong to a generation that is not used to determine the time of the arrows in a circular dial. Someone Johannes created a fascinating instrument for those who are much more comfortable to know the time in the "digital" form, but at the same time a pleasure to watch the operation of the mechanism.

The spectacle, as a mechanical "hand" over and over again writes and erases the current time, has a sedative effect and almost hypnotic. In such a watch service is easy, just once every few days to change the marker.



You can easily make yourself such a watch, if you have a 3D-printer. All necessary documentation is lined author free access , however, with the exception of the circuit board and some electronic tricks.
