Producing the perfect movement with 3D simulation

at Eterna SA

All-round solution for product creation with fewer rejects and higher machine utilization

With the 3DEXPERIENCE platform, Eterna manufacturing engineers benefit from production simulation features and automatic NC programming capabilities, thereby reducing production cycle times and machine fatigue and improving sustainability by reducing material waste.

About the customer

Eterna SA

The name Eterna is synonymous with timepieces of the highest quality, with Swiss watchmaking Tradition, and with an outstanding Spirit of innovation. The passionate desire to master horological challenges as well as to constantly improve existing Features has been driving Eterna since 1856.

Business challenge

Innovation rate

Innovations such as the self-winding wristwatch and the first electrical.

Brand image

Eterna is dedicated to perfecting the art of mechanical watchmaking combining expert craftsmanship with modern production techniques.

Employee retention

Every component of an Eterna mechanical watch is designed and manufactured here in our Grenchen facility.

Process efficiency

We recently invested in new numerical control machines to increase our production output and our manufacturing efficiency. However, we rapidly realized that our previous NC software did not have the ability to sufficiently exploit these machines.

Customer goals

Process efficiency

Eterna needed a powerful software solution to fully benefit from the capabilities of their new 3-axis CNC milling machines for watch manufacturing.

Costs reduction

A significant amount of preparation is required upstream, which is why it is important to work with a programming application that is flexible and provides fast results.

In the watchmaking profession, components are very complex and anything short of perfection is unacceptable. With the 3DEXPERIENCE platform and DELMIA V6, production cycle time is shorter because the part is right the first time.

The company selected Dassault Systèmes' 3DEXPERIENCE® platform including DELMIA Machining Pack for 3D simulation and NC programming.

“With this platform, we have a complete solution that includes DELMIA for our prismatic machining programming, CATIA for 3D design visualization and rework, and ENOVIA to manage our tooling library.”

With DELMIA’s V6 Machining application, we can efficiently program for every type of shape or contour while keeping material waste to an absolute minimum.

Dassault Systèmes partner CENIT implemented the DELMIA Machining Pack and provided training at Eterna.

Detailed project description Download

In a nutshell:

  • DELMIA Machining Pack can simulate the machining of a watch mechanism to verify that it can be done and if something is not possible
  • Necessary adjustments to the design using CATIA
  • The result we obtain during virtual simulation is the one we obtain in the real world

Results and conclusion


Moreover, a more efficient machining program means less wear and tear on the tool because there is less friction and no collisions.

Process efficiency

Production cycle time is shorter because the part is right the first time.


With this platform, we have a complete solution
