About us

Our history since 1986

1986: The company is founded by the two young new partners, Jacques Wermeille and Daniel Gerster, and the name Derwa SA is created with the letters of the two founders.

Daniel Gerster and Wermeille Jacques.

1986-88: The company moves to Mr. Gerster's premises, located in the basement of his family home in Noirmont. Derwa SA specialises in the manufacture of stamps for watch straps and cases. Nevertheless, the company remained in the same premises until December 1988.

1989: It then moved to Saignelégier, in the new relay factory located in the industrial zone, currently taken over by the Brasserie des Franches-Montagnes. The company, still active in the manufacture of stamps and injection moulds, adds a new string to its bow: it develops a plastic injection department.a new partner joins the company in the person of Alain Varrin.the company will count up to a dozen employees.

1995: Derwa sells its injection department to concentrate solely on its primary activity, i.e. the manufacture of stamps, moulds and tooling, and develops an activity that will later become its main activity: subcontracting by electro-erosion. 1999: Alain Varrin leaves Derwa with new projects. Jacques Wermeille becomes the sole shareholder again.

2006: The company abandons the manufacture of stamps in order to devote itself fully to EDM subcontracting.  

2007: The company buys a renovated industrial building with a surface area of 600m2 and moves to its new and current premises on Rue du Pâquier in the centre of Saignelégier. Derwa Technology SA is at the forefront of technology thanks to the latest generation of equipment and modern production and organisation processes.

2018: After more than 30 years, Jacques Wermeille decides that it is time for him to pass the torch. The company will be taken over by his son, Laurent Wermeille, and his workshop manager Maël Krause under the new name of Derwa Technology SA

Recognised know-how

Our premises are located in the heart of the Franches-Montagnes, in the upper part of the Swiss Jura, in an economic area strongly linked to the watchmaking and micromechanical industries. We are active in the fields of watchmaking, machine tools, aeronautics and aerospace, as well as for all types of electroerosion work.

A complete and well-maintained machine park also allows us to carry out various complementary work to electroerosion.  These include milling, laser marking and bead blasting.

Thanks to an experienced and dynamic team providing quality work, we can offer our customers tight deadlines and competitive prices. This is our expertise.
