Jules Frédéric Jürgensen (1808-1877), son of Urban Jürgensen, Jules was born in Le Locle, but moved with his parents to Denmark as a child. In 1830, after his father’s death, 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 Jürgensen of Copenhagen.

Jürgensen’s patent lever escapement features a long pallet fork, which allows for a larger balance wheel, resulting in a more constant rate of oscillation and consequently, greater precision.
