Inclined plane clock This clock is based on a system already used at the beginning of the 17th century. The motive force of the clock is provided by a WEIGHT placed inside the movement acting against the resistance of the development of the going train, thus replacing the barrel. On the axis of the centre wheel is fixed a lever with a WEIGHT which serves as a speed regulator. During the descent, the cylinder drives the movement and the dial, while the hour hand (or the hour and minute hands) weighted remains fixed and indicates the countdown time of the movement of said cylinder. This clock does not need to be wind; it is placed manually, every week, at the top of the inclined plane in order to cover the slope in seven days. Like many so-called fancy clocks, these kinds of pieces regularly return to fashion. We know some rare examples of clocks that descend on an inclined plane of the 17th century and some more or less detailed descriptions. The Arthur Imhof SA house in La Chaux-de-Fonds has made a specialty of this type of clock since the 1980's. To be sold without reserve
