THE STORY OF THE BIDYNATOR
Unlike today, in the midst of the last century, small clockwork manufacturers in particular dominated the Swiss watch market. They continuously improved the quality of the works and developed new functions. Their innovations influenced the products of the big watch brands for decades.
Among the great innovators of the 40s and 50s was Friedrich Meyer. In 1942 he developed the first automatic movement with a double-sided winding rotor at the clockwork company FELSA in Grenchen. Under the name "Bidynator" it conquered the Swiss watch industry.
