Overview
Langendorf Watch Company SA was a Swiss watch manufacturer based in Langendorf, in the canton of Solothurn. Founded in 1873 by Colonel Johann Viktor Kottmann, the enterprise began by making ebauches, or unfinished watch movements and movement components, for other manufacturers. It later developed into an integrated producer of watch movements, complete watches, alarm clocks and export products sold under several names. The company operated its Langendorf production facilities for exactly a century, from 1873 to 1973. The business originated in an industrial site that had previously been used for chicory production. Kottmann rebuilt the facility for watch-related manufacturing and initially employed approximately 70 to 80 workers. After an economic crisis around 1880, Karl Kottmann took control and recruited specialist workers from western Switzerland. Under his direction the factory adopted more rationalized and mechanized production methods, expanded its output and gradually reduced dependence on outside suppliers. By 1890, the workforce had reached roughly 1,000, and contemporary accounts regarded the factory as possibly the largest watch producer in the world. Langendorf was also notable for the social infrastructure associated with its industrial development. The company and the Kottmann family supported worker housing and training, schools, water infrastructure and electric lighting in the village. These measures helped give the enterprise a reputation for social responsibility while also strengthening the local industrial community. The company produced watches under the Langendorf name and under a range of other brand names, including Aliada, Barracuda, Carex, Cavalier, Lancet, Stratford, Valogene and Piquette. Its products were exported widely, and some watches were cased in destination markets to reduce import duties. The United States was among the export markets, with imports handled by the American Swiss Watch Company during the early twentieth century. Langendorf also supplied military and pilot watches during both world wars, including early wristwatches intended for trench use and watches fitted with the company’s 9XX movements. The company’s best-known brand was Lanco, an abbreviation of Langendorf Watch Company. Introduced as a brand name in the 1950s, Lanco became associated with detailed workmanship and technically varied designs. Models included mechanical watches, alarm watches and later experimental products such as the Lanco-Fon, Flying Saucer, Club 77 and Jump Hour. During its later period, the brand also used movements from external suppliers, including Valjoux, Angelus and the Tissot Astrolon caliber 2250. Family control ended during a period of structural difficulty in the Swiss watch industry. The Kottmann family remained involved until 1964, but after the death of Hans Kottmann that year and continuing business challenges, Langendorf joined the Schweizerische Gesellschaft für Uhrenindustrie AG. In 1965 it was acquired by SSIH, the major Swiss watch group formed through the earlier Omega-Tissot combination. SSIH valued Langendorf’s Lanco name and its relatively sophisticated, semi-automated production equipment. Production at the Langendorf facilities ended in 1973, after which the Lanco brand was transferred to the Aetos Watch Company within the SSIH structure. Lanco was later revived for a period in the 1970s and remained visible in licensed distribution in South Africa in the late 1990s, but the original Langendorf manufacturing company no longer operated. The former factory site became a shopping centre in 1977.
History
Langendorf Watch Company SA was established in 1873 when Johann Viktor Kottmann converted an existing industrial site in Langendorf, Switzerland, from chicory-related production to the manufacture of watch ebauches and movement parts. The initial workforce numbered approximately 70 to 80 people. Around 1880, the enterprise experienced a severe financial and operational crisis. Karl Kottmann, Johann Viktor’s son, assumed control and brought in skilled workers from western Switzerland. His management introduced more systematic and mechanized production, helping the company secure new orders and expand rapidly. By 1881 the factory employed approximately 200 people. During the following decade it deepened its manufacturing capabilities and became increasingly self-sufficient in the production of watch components. Karl Kottmann also supported worker welfare and local infrastructure, including housing, training, schools, water facilities and electric lighting. After his death in 1890, technical director Lucien Tieche took over. The company adopted the name Langendorf Watch Company and by that time employed about 1,000 workers. It supplied movements and parts to major watch manufacturers, particularly in the Neuchâtel region, and was described in contemporary accounts as possibly the largest watch producer in the world. The company continued to expand its product range. An advertisement from 1916 claimed a workforce of about 1,500 and daily production of 3,000 timepieces. Watches were exported under the Langendorf name and numerous secondary brands, while some products were cased in the destination country to avoid import duties. In 1920 the company added alarm clocks. It opened a branch in Lommiswil in 1924 and an agency in La Chaux-de-Fonds in 1925. During the First and Second World Wars, it was known for producing military and pilot watches, including early trench-use wristwatches and watches fitted with its 9XX movements. The Kottmann family continued to direct the company through the first half of the twentieth century. Ernst Kottmann managed it from 1902 until 1942, introducing the transition from steam power to electricity. Rudolf Kottmann then led the company until 1964. Hans Kottmann briefly succeeded him but died in an accident later that year. Guido Kottmann and a family committee subsequently managed the business during increasingly difficult conditions in the Swiss watch industry. In 1964 Langendorf joined Schweizerische Gesellschaft für Uhrenindustrie AG. The following year it was acquired by Société Suisse pour l’Industrie Horlogère SA, commonly known as SSIH. SSIH had emerged from the earlier Omega-Tissot combination and was consolidating numerous Swiss watch businesses. Langendorf was attractive because of its Lanco brand and its modern, semi-automated manufacturing line, which could support quality production at comparatively lower cost. The Lanco name had been introduced in the late 1950s and became the company’s most recognizable brand. Its range included conventional mechanical watches, pocket watches and alarm watches, as well as designs such as the Lanco-Fon and Flying Saucer. After the brand was revived in the 1970s, it adopted more experimental styling and included models such as Club 77 and Jump Hour, along with chronographs using Valjoux and Angelus movements and a model using the Tissot Astrolon caliber 2250. Manufacturing at Langendorf ended in 1973, exactly one hundred years after the factory was founded. The Lanco brand was transferred to Aetos Watch Company, another SSIH subsidiary. The former factory building became a shopping centre in 1977. SSIH later merged with ASUAG in 1983, changed its name to SMH in 1986 and became The Swatch Group in 1988. The Lanco name was sold during SSIH’s financial difficulties in 1981 and was later used under license in South Africa, including distribution reported in 1998. These later uses did not restore the original Langendorf manufacturing operation.
