To fully wind the mainspring, the rotor of an automatic watch needs to complete more than 2000 revolutions. Although it weighs only a few grams, the forces exerted on different components of the automatic winding system during rapid movements may be as much as 1000 times that of gravity. Apart from a sophisticated design, the material chosen is also crucial to protect the parts against wear and tear. In the 52000-calibre family, components of the automatic winding system that are subject to pronounced stress, such as the pawls, the automatic wheel, or the cam, are made of virtually wear-free ceramic. Thanks to the use of this high-tech material, which can also be found in areas like medical technology or in space exploration, they are virtually wear-free and have a much longer lifespan.
