Edouard Heuer founded his watch manufacture in 1860 in Saint-Imier. In 1867 the company moved to Bienne, and the series production of chronographs began in 1882, as Heuer receives the first patent for a timer mechanism. In 1887, Heuer invented the oscillating pinion, which is still used today by well-known watch brands. This heritage is reflected in period advertisements, which note that the company is a specialist in simple and complicated chronographs and repeaters, as well as jewels for watches and jewelry.
