What Is an ETA Movement? The Swiss Engine Powering Iconic Watches Worldwide
What is an ETA Movement? The Backbone of Swiss Watchmaking Excellence
When it comes to determining the quality of a watch, few elements are as important as the movement inside it. A superior movement not only enhances precision and reliability but also increases a watch’s overall value. While a few prestigious brands design and manufacture their own in-house calibers, most luxury and mid-range watchmakers turn to the industry’s most trusted movement supplier: ETA SA Manufacture Horlogère Suisse.
Who is ETA?
Founded in 1856 and headquartered in Grenchen, Switzerland, ETA is now a subsidiary of the Swatch Group. The company specializes in producing blank (ébauche) movements and fully assembled calibers. Over the decades, ETA has become the world’s largest movement manufacturer, with annual production exceeding 100 million units.
ETA produces a wide range of mechanical, automatic, and quartz movements, which power watches from renowned brands such as IWC, Panerai, TAG Heuer, Tudor, Breitling, Longines, Tissot, Hamilton, Mido, Chopard, and many more. Some brands use ETA calibers as-is, while others customize them to meet their in-house standards, leading to a broad spectrum of quality tiers.
ETA’s Mission and Capabilities
ETA’s success lies in its ability to:
-
Conduct R&D in horological technologies
-
Mass-produce watch components and movements at scale
-
Manufacture both the movements and the machines that build them
-
Assemble watches in-house
-
Ensure technical consistency across the Swiss watch industry
