Welcome to the world of springs and watch parts

We produce springs for industrial applications exclusively. To do this, Haller-Jauch uses its knowledge and know-how from more than 70 years of manufacturing mainsprings for the watch industry. Our equipment and machinery have been perfected over the decades and are optimised for fast and very flexible production of middle to small-sized components.

We have available a very extensive stock of raw materials with over 800 different measurements. This enables us to produce springs with great flexibility and in very short timeframes. Using a measuring station, we determine the service life and torque of the springs.

Facts about mainsprings and watch parts

In our mainspring shop we produce springs for industrial applications and watch technology out of so-called textured steel. Textured steel means a textured carbon steel that is distinguished by its very high resistance to fracture.
