Expertise built over more than a century

Our expertise – acquired over more than a century – drives us to produce high-precision components for all watchmaking and medical applications.



The Swiss benchmark in high-precision turning.

Turning is an automatic machining process that rotates and removes material, creating components from bars or rolls of wire.

The raw material is fed into the machine and moulded by a series of tools. This produces parts with specific shapes and dimensions, depending on the number and type of tools used.
