Jeanneret

The Jeanneret name is associated with many watchmakers in Switzerland, notably in Saint-Imier but also in La Chaux-de-Fonds, Le Locle, and elsewhere. The family is best-remembered for Excelsior Park but was also key to the development of Moeris, Leonidas (along with Junior and Berna), and others.

Jules-Frédéric Jeanneret and Saint-Imier

Jules-Frédéric Jeanneret (1830-1892), originally from Valangin, moved to Dombresson and married Cécile Sandoz. The family soon included two daughters and six sons, all of whom became watchmakers.

Jeanneret established a watchmaking workshop in the village of Reprises in 1866, but it soon failed and was listed for liquidation in La Chaux-de-Fonds in 1868. After this he entered a partnership in Saint-Imier with François or Edouard Fallet called Jeanneret et Fallet by 1889. This workshop was listed at Rue de Tramelan 34A, and would be the home of the Jeanneret watchmaking family for decades. Jeanneret et Fallet produced stop watches and chronographs, a specialty of the family.

Fallet left the partnership by 1883 and starting that year it is simply listed as Jeanneret et Fils. It is likely that Jules-Frédéric's brother Ulysse Jeanneret was also involved in the firm, and he also would have received support from his brother in law, watchmaker Fritz Thalmann. Jeanneret and Thalmann both used the Colombe brand at this time, as did his son Albert Jeanneret in the 1890s.

Jeanneret et Fils was an etablisseur of high-quality anchor watches as well as stop watches, some with minute counters. The firm received a diploma in La Chaux-de-Fonds in 1881 and Zürich in 1883 and won a silver medal at the Antwerp exhibition in 1885. The Jeanneret family had registered the Pigeon brand by this time and focused on selling in England and the British Empire.

Jules-Frédéric Jeanneret died in 1892 but his widow continued to operate the firm as Vve. Jules-Frédéric Jeanneret. It continued to produce complicated watches, including chronographs, rattrapante watches, and clocks, now also for the American market. In 1895 the firm's address is shown as Rue de Tramelan 18, which is likely a new wing on the side of the former building, which was renumbered that year as 14A.

In 1892, Jeanneret licensed 1890 patent CH359 from Alfred Lugrin of l'Orient for a thin movement with an open heart balance below the stem. Lugrin would go on to found Lémania, a competitor for Leonidas, which would become the Jeanneret family firm.

Samuel Jeanneret

Cécile died in 1899 and the firm was taken over by Ulysse Jeanneret's sons, Samuel and P. Jeanneret as S. & P. Jeanneret. The company added a 13 ligne chronograph movement by 1901, and this would eventually be used in one of the first wristwatch chronographs. The company was called simply Samuel Jeanneret by 1908 and specifically offered a 19 ligne bracelet chronograph by 1913.

The firm of Samuel Jeanneret, direct successor to the 1866 firm established by Jules-Frédéric Jeanneret, was deleted from the register of Swiss companies on October 1, 1940 just one year after the death of Samuel Jeanneret in December of 1939.

Albert Jeanneret

In 1889, Jules-Frédéric's son Albert Jeanneret (1855-1899) set up a firm of his own known as Albert Jeanneret et Frères along with his brothers Henri Jeanneret-Brehm (1856-1932) and Constant Jeanneret-Droz (1858-1916). The sons moved their family and production to "Le Parc" across town from the family home. Albert Jeanneret and Fritz Thalmann had purchased an existing steam-powered factory there in 1885, and it would become known as Usine du Parc.

Albert died in 1899 after also founding Moeri & Jeanneret.

Henri Jeanneret-Brehm and Excelsior Park

Albert likely focused more on Moeri & Jeanneret, located across the Rue du Pont, after its founding in 1894 and may have even left the company. Henri and Constant continued to run the park factory as Jeanneret Frères until about 1904. At this point, Constant Jeanneret left the firm and it was known thereafter as Jeanneret-Brehm.

In 1891, Jeanneret et Frères received a patent for a new stopwatch movement with a distinctive J-shaped bridge. This would soon be sold under the newly-registered brand name, Excelsior. In addition to Excelsior, Usine du Parc produced watches under the Colombe, Diana, and Cervin brands.

The factory began producing a 13 ligne chronograph movement around 1902, and this would become popular a decade later as the basis for some of the first wrist chronographs. It was notably used by Gallet, Zenith, and Girard-Perregaux.

With great success for these complicated movements, Jeanneret-Brehm purchased the Le Sentier firm of H. Magnenat-LeCoultre in 1911. This company was well known as a producer of minute repeaters, some with chronograph functions, under the Le Resoud brand name. Gallet supported this purchase financially, and encouraged the company to focus on the Excelsior name, since it was well-received in the English-speaking market. Soon the Anglicized name of the factory was added, giving us Excelsior Park, and this would become the name of the entire company.

Henri Jeanneret-Brehm died on August 4, 1932 at 76 years of age, but Excelsior Park continued in the Jeanneret family for many decades. Production finally stopped after 1984.

Constant Jeanneret-Droz, Junior, and Leonidas

Constant Jeanneret-Droz founded Manufacture Junior by 1902 even while still working with his brother Henri at Jeanneret Frères. The company sold anti-magnetic watches very similar to Fritz Moeri's, and given the family connection we can assume they leveraged Moeri's patent. Indeed they might even have been produced at Moeri's factory, since Jeanneret-Droz set up nearby at Rue du Pont 16.

Montres Junior also licensed a keyless works patent from Charles Perrin-Debrot in 1904, suggesting that the company also produced its own watches. Another business taken on by Constant Jeanneret-Droz was wholesaling of chronograph movements produced by rival firm LeCoultre of Le Sentier.

Constant left Jeanneret Frères by 1905 to focus on went out on his own company. He soon expanded his product range to include higher-quality anchor watches in 17 and 19 ligne sizes as well as American-style 16 ligne movements. He even offered silver and gold cases in addition to steel.

In 1911, Constant Jeanneret-Droz invested in the Leonidas Watch Factory. This brand was registered by 1902 by Ferdinand Bourquin (1845-1903) and J.-H. Jeanneret. Bourquin came from a Saint-Imier watchmaking family dating all the way back to 1841 and founder Julien Bourquin (1815-1897). The new factory was located on Beau-Site, just up the hill from both Usine Centrale and the Jeanneret home.

Leonidas had done well in the decade of its existence, but the death of Ferdinand Bourquin in 1903 likely posed issues. Constant replaced the La Popular brand with his own Junior, merging the companies to offer a complete range of pocket watches. But Constant died in 1916, just as Leonidas began offering wrist chronographs. The business was then run by Charles and Ernest Jeanneret as Leonidas Watch Factory, Les Fils Jeanneret-Droz. It would merge with Berna and High Life by 1930 and ultimately with Heuer in 1964.

Moeri & Jeanneret

By 1894, Albert Jeanneret had set up a second watchmaking business with Fritz Moeri. The new company, Moeri & Jeanneret would exploit Moeri's patent CH7547, an anti-magnetic pin lever watch movement that could be inexpensively mass produced by machines. It was initially manufactured at Usine Centrale on Rue de l'Hôpital 6, just a few blocks from the Jeanneret home, but quickly expanded to a new factory built across the street from Usine du Parc just after the turn of the century.

Moeri and Jeanneret were related through their wives: Albert and Fritz married daughters of Marie Elise, sister of Albert's father, Jules-Frédéric Jeanneret.
