Jules Frédéric Jürgensen (1808-1877) The son of Urban Jürgensen, and a very eminent watchmaker himself, 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. After his death, the family business was continued by his brother and in 1886 it was sold to an employee, H. Kiens, whose sons, Jules 1837-1894 and Jacques Alfred 1842-1912, continued the business, as did the House of Heuer subsequently. Jürgensen became watchmaker to the King of Denmark, and was made a Knight of the Légion d?Honneur and Knight of the Royal Order of Dannebrog. Between 1870 and 1876 he was a member of the commission of surveillance of the Geneva School of Horology, along with Ekegren and Potter and others; he was a member of many commissions in Switzerland judging horological contests. He stamped most of his watches on the pillar plate under the dial: Jules Jürgensen of Copenhagen.
