Notes

Jules Frédéric Jürgensen (1808-1877) The son of Urban Jürgensen, Jules was born in Le Locle but as a child moved with his parents to Denmark. In 1830, after the death of his father, the company was taken over by Jules and his brother Louis Urban. In 1833 Jules returned to Le Locle and built up a great business, which was continued by his brother and in 1886 was sold to one of the employees, H. Kiens. Jürgensen was considered to be one of the best watchmakers working in Switzerland. He stamped most of his watches on the pillar plate under the dial: Jules Jurgensen of Copenhagen.
