Swiss Watchmaking Townships
Cities built by time: where streets, light and craft were engineered for watchmaking

01 In brief
High on the Jura plateau of western Switzerland lie two towns whose very street plan was shaped by timekeeping. After a devastating fire, La Chaux-de-Fonds was rebuilt from the 1790s onwards in a deliberate grid of wide, south-facing streets — so that workshop windows on the upper floors of every house could catch the daylight needed by watchmakers working at benches below the living quarters. Together with its twin town Le Locle, it grew into the industrial heart of Swiss watchmaking, and the pair were inscribed by UNESCO as a World Heritage site for their "watchmaking town planning".
The best place to understand the story is the Musée International d'Horlogerie (MIH) in La Chaux-de-Fonds — founded by town deed on 24 March 1902 out of a watchmaking-school collection, and since 1974 housed in a striking largely underground building carved into a park slope, holding around 10,000 timekeeping objects from early clocks to modern wristwatches.
02 Why it's interesting
- 01 This is industrial urbanism: an entire city — housing, streets, schools, museums — designed as production infrastructure for one craft, and still working as a watchmaking centre today.
- 02 The region's mechanical knowledge survived quartz crises and globalization, and now powers a luxury industry and a precision-microtechnology cluster (the two towns also sit in Switzerland's watchmaking-country innovation ecosystem).
- 03 Swiss-French watchmaking know-how was recognized by UNESCO as intangible cultural heritage of humanity in 2020 — a living craft, not a relict.
- 04 The MIH itself is an artefact of engineering: a 1970s underground museum whose galleries descend through the slope in daylight-washed levels — architecture serving objects that measure time.
03 How it works
Mechanical watchmaking organizes the release of stored energy into steady, dividable time.
A mainspring stores energy; a gear train transmits it to the hands; and the escapement — an oscillating balance wheel advanced tooth-by-tooth by an anchor — divides that flow into equal beats. The beat of the balance is the pulse of the watch, typically several vibrations per second.
What the Jura contributed was organization: the region's farm-workshop system, school system and networks of specialist suppliers (the "ébauche" and finishing trades) made quality reproducible at scale decades before modern quality management had a name.
Modern manufacture adds CNC machining, robotics and materials science — silicon escapements, novel alloys — but the final adjustment of a movement is still a craft skill, learned over years and transmitted in the region's training workshops.

04 The organisation behind it
The MIH is owned and operated by the City of La Chaux-de-Fonds. Around it stands the living industry: manufactures, suppliers, schools and museums that together make the region the densest watchmaking ecosystem in the world.
05 In the real world
The region's products are on hundreds of millions of wrists, but its deeper export is a production philosophy — precision achieved through networks of specialists and standardized interfaces. That philosophy, incubated for timekeeping, now also serves medical technology and micro-engineering firms in the same cantons.
06 Can you visit?
Yes, and rewarding. The MIH is open Tuesday to Sunday (10:00–17:00). Beyond the museum, the towns themselves are the exhibit: walk the grid of La Chaux-de-Fonds, visit the watch manufactures and museums that welcome visitors (check individual booking requirements), and combine with Le Locle and the surrounding Jura landscape.
