Beschreibung

Ref. MG-002302 - For thousands of years, researchers and inventors have repeatedly attempted to construct a perpetual motion machine, a machine that, once set in motion, continues to move indefinitely. Without any external energy being supplied to the system, the machine itself generates freely available energy. It was not until the middle of the 19th century that physics, with the formulation of the law of conservation of energy, removed the basis for all considerations of perpetual motion. Nevertheless, the fascination with it remained undiminished. The HAMATIC is certainly not a perpetual motion machine; the first self-winding watch from Moritz Grossmann draws its kinetic energy from an external source. A pendulum rotor in the shape of a hammer cleverly harnesses the energy generated by the wearer's movement, transferring it via the ratchet wheel to the mainspring in the barrel. The dream of infinite motion is thus realized through an external energy supply. It can therefore be said with a clear conscience that the HAMATIC is one of the most beautiful and difficult supposed perpetual motion machines.
