Nivarox is an alloy of iron, nickel, chromium, titanium and beryllium used for balance springs. Nivarox springs are distinguished by their good anti-magnetic and temperature compensation features. The name is taken from the German properties of the alloy, "nicht variabel oxydfest" ("non-variable, non-oxidizing").
History
Nivarox was developed by Reinhard Straumann of Waldenburg in Northwest Switzerland. Although he was technical director of Thommens Uhrenfabrik at the time, Straumann developed the compound in his personal laboratory in his spare time. In 1931, he collaborated with the German materials firm Heraeus to create a new hairspring material that would not change in elasticity due to changes in ambient temperature. The resulting material, an alloy of nickel, iron, and other metals, was particularly valuable in the production of hairsprings and balance wheels. Named Nivarox, it was resistant to fracture, corrosion, and magnetism and was perfected in 1933 and patented in 1935.
Straumann left Thommen in 1934 and founded Nivarox SA in Saint-Imier that year.
In 1977, Fabriques de Spiraux Réunies of Geneva took over Nivarox SA of Saint-Imier and Virola SA of Bienne. Although those companies technically were part of FSR, the new company was named Nivarox SA and was located on Rue du Progrès 125 in La Chaux-de-Fonds rather than Geneva. Production of Nivarox springs was centered in Saint-Imier, as it had been since the 1930s, while the Geneva, La Chaux-de-Fonds, and Bienne factories concentrated on Isoval. All of this was soon consolidated, with Nivarox SA and all of its production and management relocated to Saint-Imier.
This consolidation continued in 1983 as Nivarox SA was merged with the watchmaking division of Fabriques d'Assortiments Réunies of Le Locle. The new firm was called Nivarox-FAR and was managed by E. Girard, former director of Nivarox SA. The two entities continued to operate separately for a time, with Nivarox centered in Saint-Imier and FAR in Le Locle. The former FAR workshops in Le Sentier, Dombresson, and Vicques remained open.
Straumann became director of Tschudin + Heid AG, a watch component producer in Waldenburg, and continued working to create new materials in a laboratory there. He patented a new mainspring material, Nivaflex, in 1948 and founded another company in Saint-Imier to develop this material, Nivaflex SA, in 1948.
Straumann's Waldenburg research laboratory became Institute Dr. Ing. Reinhard Straumann in 1954, with research continuing on new materials. The institute focused on areas of interest to Straumann, chiefly ski flying, watch materials, and test equipment. The company would be renamed Straumann AG in 1990 and would focus on development of dental implants. Straumann's grandson founded Precision Engineering AG in 2001 to continue oversight of the Nivarox alloy, and his company merged with H. Moser & Cie. under MELB Holding in 2012.
Nivarox-FAR
Nivarox-FAR is the name of the manufacturer of the corresponding balance springs and assortments. It is part of Swatch Group.
Other Producers
Although Nivarox-FAR produces most balance springs used in Swiss and other European watches, a few companies produce their own springs using similar alloys. Rolex, Parmigiani, Precision Engineering AG, F. P. Journe, and A. Lange & Söhne all have the capability to produce their own Nivarox springs. Thanks to their Richemont connection with Lange, Jaeger-LeCoultre also produces springs from Lange material.
Seiko uses their own SPRON alloy for in-house spring production.
