1961 – 1970: Mechanical movements under the Ronda brand

For many years, the Swiss authorities protected the watch manufacturing industry by legislation which, among other things, granted ébauche production rights solely to its major players. After a long and tough battle, Ronda finally won the right in 1961 to manufacture its own pallet and Roskopf blank movements. The company also manufactured the entire assortment of these mechanical movements in the form of components such as escape wheel, pallets and balance with its staff. The manufacture of assortments for other brands was abandoned around this time.
