was formed in 1961 by the legendary pilot and flight instructor Helmut Sinn. They began manufacturing flight watches based on his extensive aviation experience, this was primarily based on Mr. Sinns dissatisfaction with the watches that were available for pilot and navigational purposes at that time. His own designs incorporated the features and functionality that he felt more fit for purpose as an instrument watch. This is a design philosophy that has transcended the companys culture right through to the present day. Sinn is now the worlds most eminent manufacturer of high quality, precision, functional and purposeful instrument watches.
