Valjoux calibres

Valjoux is a famous maker of watch movements, primarily chronographs. Originally known as Reymond Frères SA, the company was renamed Valjoux in 1929 and merged into ETA as part of the Swatch Group. However, the name, Valjoux, is still used for chronograph movements derived from the company's heritage.
