Saint-Imier is a watchmaking town in the Jura triangle in Switzerland.
Saint-Imier (sometimes written as “St-Imier”) is a small village in the Swiss Jura between La Chaux-de-Fonds and Bienne. It is the birthplace of watch manufacturers such as Longines, Marvin, Leonidas, movement maker Excelsior Park, and (temporarily) the Swatch Group subsidiary Swiss Timing. The companies Breitling and Heuer were also founded here.
