The watch industry is not just limited to the Jura valleys. Valais also plays a leading role thanks to its innovative and creative businesses. The success of these companies is down to their visionary, bold and discreet pool of talent who are specialists in the field of microtechnology. Infinitely small pieces are machined to within a thousandth of a millimetre and their unrivalled quality is recognised by some of the world’s biggest brands.


Mimotec, with its global reputation for high-end watchmaking, manufactures micro- parts such as wheels and springs for the mechanical movements of watches using the UV LIGA method. The process can be compared to photofabrication and makes production more competitive than when using traditional methods. In partnership with its subsidiary Sigatec, Mimotec can also provide customised miniature components. Often used for decorative purposes, this technology allows components to be identified, thus preventing counterfeiting.

Three million units are produced for watchmakers every year in the Mimotec factory in Sion.
