Product Details

The HAMATIC, the first self-winding watch from Moritz Grossmann, draws its kinetic energy from an external source. A pendulum-style hammer weight skillfully uses the energy generated through the wearer’s movements to transfer it via the ratchet wheel to the mainspring in the barrel, meaning that an external energy source makes the dream of infinite motion come true. The HAMATIC is available in 18k rose (shown) or white gold with a choice of straps and fasteners.

Throughout millennia, researchers and inventors strived to build a perpetual motion machine, a device that would continue to move indefinitely once started. Without any external source of power, it was believed that the machine itself would generate an unlimited amount of energy. It was only with the formulation of the law of conservation of energy in the middle of the 19th century that physics quashed the principle of perpetual motion. Nevertheless, people’s fascination for the concept remained unbroken. Of course the HAMATIC does not purport to be a perpetual motion machine, but it's still safe to say that the HAMATIC is one of the most beautiful and complex examples of would-be perpetual motion.
