In 1860, Edouard Heuer opened his first watch workshop in St. Imier, a small town in the Swiss Jura in western Switzerland. Since the founding, Edouard Heuer`s innovations have been the characteristic element of the manufactory. Heuer is the inventor of the famous "swinging gear" for mechanical stopwatches, patented in 1887. This technical innovation is a cornerstone for accurate time measurement being still used even today by leading manufacturers of mechanical chronographs. It´s part of the Caliber 1887 for example, which is completely developed and manufactured by Heuer.
