From workshop to factory: industrial watchmaking
How watchmaking moved from guild workshops and cottage industries to machine-made, interchangeable parts — in Beaucourt, Waltham, the Jura and beyond.
By the end of this lesson you will be able to:
- Describe the établissage system
- Explain the American system of interchangeable parts
- Outline how the Swiss industry responded
For most of its history a watch was the work of many hands. In London, Geneva and the Jura, specialist workers made frames, wheels, springs, cases and dials, and a 'maker' — whose name appears on the dial — assembled, finished and sold the result. Industrialisation did not abolish this division of labour; it mechanised it.
Établissage
In the Swiss Jura, the system known as établissage organised the work of home-based specialists through merchant-assemblers (établisseurs). Raw movements (ébauches) came from specialist makers; finishing, escapements, cases and dials were contracted out. This flexible network made Switzerland a leading producer of watches by the nineteenth century.
Machines in Beaucourt
Frédéric Japy founded a factory at Beaucourt, near Montbéliard, in the 1770s, using machines of his own design to make ébauches in quantity. Japy became one of the great industrial names of French clock and watch production.
The American system
In Massachusetts, Aaron Lufkin Dennison and Edward Howard set out in 1850 to make watches with machine-made, interchangeable parts. Their company moved to Waltham in 1854 and, after several reorganisations, became the American Waltham Watch Company. Elgin, Hamilton and others followed. American factories produced accurate, affordable watches in very large numbers.

1876: the Swiss response
At the Philadelphia Centennial Exhibition of 1876, Swiss observers were shocked by the quality and output of American factories. A report by Jacques David of Longines described the gap in detail and helped push Swiss firms towards integrated manufacture with machine tools, while keeping the strengths of the specialist network.
Railroad standards
In the United States, railway timekeeping became a matter of public safety. After serious accidents, notably a collision at Kipton, Ohio, in 1891, railroads adopted inspection systems and minimum standards for watches — organised by Webb C. Ball among others — that included open faces, lever setting, at least 17 jewels and adjustment to temperature and positions.
| System | Where | Characteristics |
|---|---|---|
| Guild workshop | London, Paris, Geneva, Augsburg | Master and apprentices; parts from specialists |
| Établissage | Swiss Jura | Networks of home-based specialists coordinated by assemblers |
| Ébauche factory | Beaucourt, the Jura | Machine-made raw movements finished elsewhere |
| Integrated factory | Waltham, Elgin, later Swiss firms | Interchangeable parts made and assembled in one plant |
Interchangeable parts
The heart of the factory system was the gauge. Parts were made by machine to fixed dimensions, checked against gauges and kept in stock, so that a broken wheel or screw could be replaced without hand fitting. Automatic screw machines, wheel and pinion cutters and jewelling lathes reduced the work of skilled finishers. In Switzerland, Ernest Francillon brought production under one roof at the Longines factory in Saint-Imier in 1867, and in 1926 the main Swiss ébauche makers combined as Ébauches SA, later part of the ASUAG group founded in 1931.
Britain, Roskopf and the cheap watch
British watchmaking remained largely a hand trade in Prescot, Coventry and Clerkenwell. The Lancashire Watch Company, founded at Prescot in 1889 to adopt factory methods, closed in 1910. Meanwhile, Georges-Frédéric Roskopf's 'proletarian' watch of 1867, with a pin-lever escapement and few parts, showed that a working watch could be sold cheaply. Pin-lever watches by Ingersoll, Westclox and later Timex made watches affordable to almost everyone in the twentieth century, and in Japan Kintaro Hattori's Seikosha factory, founded in 1892, grew into one of the world's largest makers.
| Clue | What it tells you |
|---|---|
| Calibre and ébauche marks under the dial or on the pillar plate | Who made the raw movement |
| Movement serial number | Approximate year, from the factory's records |
| 'Swiss' or 'Swiss made' on the dial | Swiss origin under the rules of the period |
| Letter codes stamped on Swiss movements imported into the United States | US import duties paid from the 1930s onward |
| Railroad grade markings, such as 'Adjusted 5 positions' | A movement made to railway standards |
