Who? The giant of Swiss movement manufacturers that started life as the Ebauche business of Eterna watches. When Swiss laws in the 1930s mandated that you could not make complete watches and movements, Eterna split into two companies- Eterna Watches and ETA. ETA then because part of the giant Swiss watch components group AUSAG, which eventually became Swatch. Swatch then decided to integrate its many movement brands ( including ETA, ESA, Lemania, Valjoux and Unitas) into a single brand- ETA. This is the reason that the Valjoux 7750 movement of the 1970s is now known as the ETA 7750.
The strategic direction of ETA has perhaps been the major driver towards changes in the movement market- more on this later.
