Swiss International Watch Co. The founder of the prestigious Swiss International Watch Co. was an American engineer F. A. Jones from Boston and previously worked for E. Howard Watch & Clock Company. F. A. Jones and C. L. Kidder worked together from about 1869 to 1872 building up a new firm which was the only North-Eastern watch factory founded in Switzerland by Americans with machinery made in America. Mr. C. L. Kidder returned to the U.S.A. in 1872 and took on a position with Cornell Watch Co. as first superintendent in the new Newark factory. Mr. Jones stayed to continue building up the factory which was completed in spring of 1875. F.A. Jonesfiled bankruptcy in December of 1975 and in 1876 returned to the U.S.A. The I.W. Co. factory started by F.A. Jones was short lived and produced about 5,000 watches. In 1877 the production of the factory (now called I"Internationale Uhrenfabrik") was delegated to F.F. Seeland of New York. In 1879 Mr. Seeland was removed from his position by managing director Johann Rauschnbach. The company today is still making precision, hand crafted watches.
