Already at the tender age of 20, Edouard Heuer founded a watch comptoir in St.Imier which was so well run that this year already in 1864 it was possible to move into larger business premises in Biel.
As early as 1880, Heuer became the first manufacturer to mass-produce chronographs and could name a number of its own patents.
When Ed Heuer died in 1892, his sons Jules and Charles took over the helm and created various watches such as a chronograph with pulsation scale, a car clock and the "Microsplit", a chronograph that could measure the time to 1/100 second.
The subject of wristwatches was not neglected and already in 1913 the first ladies wristwatches were made - later also stopwatches and chronographs for the wrist in the workshops of the company Heuer.
Already in 1930, Heuer patented a watertight housing and in the following years considerably increased its product range.
In 1963, the model Carrera starts and from 1969 you could buy at Heuer the first Automatic Chronograph. In the 70s, the range was extended by a few quartz chronographs.
In 1964, the Ed.Heuer and the Leonidas Watch Factory merged to form Heuer-Leonidas, Biel.
To the most famous models of the company Heuer belong, for example, the Monaco, Monza, Carrera, Autavia, Easy Rider, Silverstone, Kentucky, Camaro, Montreal, Cortina and of course the Bundeswehr Chronograph 1550
