====== Felsa ====== **Felsa** was a [[Swiss]] watch movement manufacturer founded in [[Grenchen]] in [[1918]] and becoming part of [[Ebauches SA]] in [[1928]]. ===== History ===== Felsa was a relative newcomer to [[Grenchen]], established in [[1918]] close to the huge [[A. Schild]] factory. The company joined A. Schild, [[Adolphe Michel]], [[FHF]], and others under the [[Ebauches SA]] banner in [[1928]]. Felsa became an innovator in the 1930s with designer [[Friedrich Meyer]], who patented an automatic winding mechanism in [[1942]]. A bi-directional winding mechanism was patented in [[1947]] by Meyer. This was used in the well-known [[Bidynator]] movement which was used by [[Breitling]], among other brands. Because of Felsa's successful bi-directional automatic winding system, they were allowed to specialize in automatic movements by the cartel of Swiss movement makers, Ebauches SA, along with [[ETA]] and [[A. Schild]]. ===== See also ===== * [[Felsa calibres]] * [[Bidynator]] * [[Ebauches SA]] {{tag>Movement_manufacturers Movement_manufacturers_Switzerland Ebauches_SA Grenchen}}
