This is the only known Jürgensen watch with these two complications. In addition, it has an extremely high finish with 40 jewels and a very finely executed escapement, and an alarm with its own gong. It was most likely made on special order for an important client. We would like to express our gratitude to Mr. John Knudsen, the author of a monography on the Jürgensen family, who has confirmed that to his knowledge this is the only existing Jürgensen watch combining repeater and alarm. 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, Jules and his brother Louis Urban took over the company. Three years later, in 1833 Jules returned to Le Locle and built a successful business. The family business continued to be run by his brother until 1886, when it was sold to one of the employees, H. Kiens. The latter?s sons Jules (1837-1894) and Jacques Alfred (1842-1912), and later the House of Heuer, carried on the business. Jürgensen became watchmaker to the King of Denmark, 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, Potter and others; he was a member of many commissions in Switzerland judging different horological contests. He was considered to be one of the best watchmakers in Switzerland. He stamped most of his watches on the pillar plate under the dial: "Jules Jurgensen of Copenhagen".
