Baehni

Baehni et Cie was a Bienne-based maker of balance springs founded in 1863. It was one of the five companies that combined in 1895 to form a cartel to corner the production of these springs, Société des Fabriques de Spiraux Réunies (FSR), with Baehni's Bienne operation taking on most volume production.

History

Jean Baehni-Ronget and his wife Anna (née Ronget) founded a watch regulation business in La Chaux-de-Fonds in 1863. The company began producing balance springs within a few years, and the company grew to be the world's largest producer in a few decades. The company relocated to Bienne by 1877.

A partnership between Jean Baehni-Ronget and La Chaux-de-Fonds based watchmaker Georges Tissot-Balmer was formed in 1888, with Jean Baehni junior also joining the firm at this time. The company pushed for the formation of a balance spring cartel, and was a founding member of Société des Fabriques de Spiraux Rèunies (FSR) in 1895. Jean Baehni-Ronget's two other sons, Eugen and Charles Baehni, also joined the firm in 1897 as the company diversified into construction of machines and transmissions.

Jean Baehni-Ronget died and the firm was taken over by his widow Anna and three sons in 1900. Charles Baehni left the firm in 1913 and Jean Baehni junior died in 1915, leaving the company in the hands of Eugen Baehni and his son Paul Eugen Baehni (1894-1970). Anna died and was removed from management in 1923.

Baehni & Co. remained a major producer of watch springs through 1954 as part of FSR.
