Movement manufacturer
ETA
Also recorded as: ETA SA Manufacture Horlogère Suisse · Valjoux · Unitas · Peseux · ETA SA
The dominant Swiss movement maker, created from Eterna's ébauche business and later home to Valjoux, Unitas and Peseux.
ETA was established in 1932 when Eterna's movement production became a separate company within the Ébauches SA group. Over the following decades the Swiss ébauche industry consolidated around it; Valjoux, Unitas, Peseux and other specialists were merged into ETA in the 1980s.
ETA engineers Ernst Thomke, Elmar Mock and Jacques Müller developed the Swatch (1983), whose low-cost plastic quartz movement helped Swiss watchmaking recover from the quartz crisis. ETA calibres such as the 2824-2, 2892-A2 and Valjoux 7750 have powered watches of many brands.
