La Chaux-de-Fonds is a city in the canton of Neuchâtel in western Switzerland, located in the Jura mountains at an altitude of approximately 1,000 metres. With a population of around 38,000, it is the largest city in the Swiss watchmaking heartland and, together with the neighbouring town of Le Locle, was inscribed in 2009 on the UNESCO World Heritage List as La Chaux-de-Fonds / Le Locle, watchmaking town planning, recognising its status as a city designed and built around the watchmaking industry.

Historical development

Watchmaking arrived in the Neuchâtel Jura in the seventeenth century, brought by Huguenot refugees from France and developed locally under the patronage of the Daniel JeanRichard family of Le Locle in the early eighteenth century. The trade flourished in the cottage-industry mode (établissage), with farmers and small workshops producing watch components during the long winters and assembly carried out by specialist établisseurs in the towns. By the early nineteenth century, La Chaux-de-Fonds had become the principal centre of Swiss watchmaking, exceeding its eastern rival the Geneva-Vallée de Joux corridor in volume.

The 1794 great fire destroyed much of the medieval town, and the rebuilding from 1830 onward followed an unusually deliberate grid plan designed by the engineer Charles-Henri Junod to optimise daylight reaching workshops on the upper floors of buildings. The distinctive long, parallel streets and the consistent four-to-five storey building heights are the visible expression of this planning philosophy. The city's planning, alongside the related plan of Le Locle, is the principal subject of the UNESCO inscription.

The watchmaking industry

Major Swiss watchmaking firms based in or originating from La Chaux-de-Fonds include Girard-Perregaux (founded 1791), Cartier (its watch movement workshops, in Cartier Manufacture nearby), TAG Heuer (until its 1999 acquisition by LVMH and subsequent partial relocation), Corum, Eberhard, and Greubel Forsey. Many firms historically based in the city have moved or been absorbed into larger groups, and the contemporary landscape reflects two waves of industry consolidation: the quartz crisis of the 1970s and 1980s, and the luxury-conglomerate accumulation of the 1990s through 2010s.

The Musée International d'Horlogerie (MIH), founded in 1902 and rehoused in a purpose-built underground museum in 1974, is the principal public institution dedicated to watchmaking history and houses one of the world's most comprehensive collections of timepieces, clocks, and watch movements.

Karl Marx and the city

La Chaux-de-Fonds occupies a curious place in nineteenth-century intellectual history. Karl Marx, in Capital Volume I, cited the city as an exemplary case of a town built around a single industry. The reference is brief but well-known among economic historians. Lenin visited the city in 1917 during his Swiss exile.

Architect and education

The architect Charles-Édouard Jeanneret-Gris, known as Le Corbusier, was born in La Chaux-de-Fonds in 1887 and trained at the city's School of Applied Arts (École d'Art) before beginning his architectural career. Several of his early houses, including the Villa Schwob (1916), are in the city. The watchmaking-school tradition that produced Le Corbusier's training continues today through the Ecole Technique des Métiers (formerly the Ecole d'Horlogerie), which trains contemporary Swiss watchmakers in techniques from balance-spring manufacture to complicated movement assembly.

Significance

For the modern watch and jewellery trade, La Chaux-de-Fonds remains an industrial centre of consequence despite the partial relocation of major brands. The Cartier Manufacture, Greubel Forsey, Girard-Perregaux, Ulysse Nardin (originally based in Le Locle) and various component suppliers continue to operate from the city. Trade visits to brand workshops, the MIH, and the Vallée de Joux high-complication ateliers form the standard pilgrimage for serious watch collectors and trade buyers.
