In 1989 the engineer, architect and designer John C. ErmelDue to an order for a new wristwatch design, the idea of ​​making the diversity of the day and night cycle visible through a radially movable hour hand. So that the clock can be read in the usual way, he arranged the hour scale on a so-called "Pascal's worm" - a circular conchoid, a special cycloid that is created by superimposing the usual clockwise rotation with translational movements in the radial direction - in in this case a sinusoidal oscillation with a phase of 24 hours. The associated mechanism for controlling the hour hand has been further developed over 10 years and is a real marvel of Swiss watchmaking. In 1999, Dipl-Ing. John C.
