The motorist of time
ETA SA Manufacture Horlogère Suisse has occupied a unique position in the watchmaking industry since 1793. Drawing inspiration from an unparalleled technical, industrial and human heritage, it has shaped its expertise (handed down over decades) to build the future.
Today, ETA SA Manufacture Horlogère Suisse uses this unique expertise as a foundation for the ongoing development of new industrialisation technologies to create Swiss Made quartz and mechanical movements.
Its production sites, located in the foothills of Jura and the Swiss cantons of Valais and Ticino, combine the company’s full expertise in the production and assembly of movements and watches which are considered global benchmarks for their reliability and performance.

History
ETA SA Manufacture Horlogère Suisse develops and produces quartz, mechanical and Swatch watch movements. The company’s headquarters are in Grenchen (Solothurn). ETA Manufacture Horlogère Suisse is the motorist of time at the heart of the Swatch Group www.swatchgroup.com
Before becoming a single undertaking in 1985, the ETA SA brand consisted of a number of ébauche factories across the whole of the Swiss Jura arc grouped together under the name Ebauches SA. This plurality allowed Ebauches SA to offer a wide range of products, as each affiliated company specialised in a particular niche (simple watches for men, chronographs, small watches for women etc.).
The group’s first ébauche workshop and business was opened in Fontainemelon (Neuchâtel) in 1793 by four master watchmakers. This date marks the founding of what is now ETA SA Manufacture Horlogère Suisse, who would continue to act as a motorist of time over the next four centuries thanks to the expertise of its employees and their mastery of watchmaking techniques.
