Presently based in Switzerland, Urban Jürgensen is a luxury watch maker founded by a Danish watchmaker of same name. Originated in the 18th century, this brand was revived in the 1980s by Peter Baumberger with the assistance of acclaimed master watchmaker Derek Pratt.
History of Urban Jürgensen Watches
The story begins at the time Christian VI was King of Denmark and Norway, Duke of Schleswig-Holstein, a child named Jürgen Jürgensen was born, and he was to have great significance for watchmaking history.
He was both the father of the most famous Danish watchmaker Urban Jürgensen and at the same time the founding father of the horological dynasty which was to revolutionize the outdated structures of the clock and watchmaking craft in Denmark and Switzerland. Through their use of new theoretical findings and practical working methods, they subsequently achieved the highest recognition both in Denmark and Switzerland.

Among the world’s greatest watchmakers of the 18th and 19th centuries, members of the Jürgensen family, notably Urban and Jules, worked alongside other horological geniuses such as Houriet, Breguet, Berthoud and Arnold. They have greatly contributed to the development of horology.
The watchmaking family’s roots stretch back to eighteenth century Denmark and Jörgen Jurgensen (1745-1811), founder of the dynasty. The most eminent watchmakers amongst his descendants are undisputedly his sons Urban (1776-1830) and Jules-Frederik Jûrgensen (1808-1877).
The latter two continued their father’s business by founding Urban Jürgensen & Sonner in Switzerland. Jules moved to Le Locle, Switzerland while his brother Louis was in charge of the factory in Copenhagen. After Louis Urban’s and Jules-Frederik’s deaths, the company went through several more changes of ownership but continued the tradition of chronometric timepieces.

Urban Jürgensen was one of the world’s most prominent watchmakers in the 18th century and contributed significantly to horological developments in fine mechanical watchmaking. As a result of his efforts, he was awarded an appointment as Royal Purveyor to King Frederik VI of Denmark and conferred the honour of the Royal Order of the Dannebrog, regularly supplying timepieces to the court and ship’s chronometers to the Danish Admiralty.
A brilliant and multifaceted talent, Urban Jürgensen achieved great international acclaim for his innovations in technology and science, gaining equal status with his scientific contemporaries.
The results of his research were published in 1804 in a series of articles in Danish, French and German, earning him a place in the Royal Danish Academy of Sciences and Letters. He was a brilliant engineer, a visionary far ahead of his time in many respects regarding creativity and aesthetics. As a horologist, inventor and aesthete, he must be considered one of the great talents in Denmark’s history.
Following the wish of his father Jürgen, Urban Jürgensen, spent a major part of his training as a watchmaker in Paris, London, Geneva and Le Locle in the Canton of Neuchatel, Switzerland.
It was under his management that both pocket watches and precision timekeepers for navigation and astronomy made by the Urban Jürgensen Company achieved international fame and recognition. The Danish King, Frederick VI, granted Urban Jürgensen a Royal Appointment to supply the court with watches and the Danish Admiralty with chronometers.
The use of first class materials and the extremely robust design of all the timekeepers made by the company soon made them highly coveted collector’s items, as is still the case today.
In accordance with the practice of the times, Urban Jürgensen’s sons also entered the watchmaking profession and following their father’s footsteps, traveled abroad to study and apprentice as watchmakers. After receiving recognition as masters, they joined their father’s company officially. This led to a change in the company’s structure, which was expressed in the name Urban Jürgensen & Sønner.
The sons and grandchildren of this generation went on to ensure the Jürgensen dynasty’s continued existence into the 20th century. One member of the family, Jules Jürgensen, ended up not only studying, but later settling permanently in Le Locle in the 1830s, where he was responsible for an official manufacture under the Urban Jürgensen & Sønner name.
This is the reason why the cities of Copenhagen and Le Locle are incorporated in the company logo, as a reference to the Danish and Swiss roots of the firm together with the date of its initial founding.
The Jürgensen, with their analytical approach to the processes and methods of watch production, exercised a tremendous influence on the watchmaking industry of Le Locle,and indeed the entire Canton of Neuchatel, introducing the most modern methods to the Swiss industry of the era, for which they received many accolades and were endowed with honorary status from the city of Le Locle.
In 1981, Peter Baumberger, a trained watchmaker and passionate collector, acquired Urban Jürgensen & Sonner and is the congenial successor of Urban Jürgensen’s spirit. Dr Helmut Crott became the guardian of the brand since his friend Mr Baumberger’s death.
Since its establishment, Urban Jürgensen & Sønner always cultivated a policy of maximum quality in the art of horology, with particular efforts directed at the technical perfection of the movement combined with artistically designed cases, dials and hands of classical elegance.
