Octo

Octo was a Swiss watch and clock brand active from at least 1908 through the late 1960s. It was best known for a range of 8-day movement (thus the name) but also produced other watch models. Octo clocks were first produced by Couleru-Meuri in La Chaux-de-Fonds, though the trademark was taken on by Ernest Tolck soon after. The company was later incorporated as Octo Sarl and Montres Octo SA before relocating to Bienne after World War II.

Marc Dubois, Léon-N. Robert, and Octo

The 8-day wristwatch and "Octo" brand originated in the Couleru-Meuri family. The brand was registered by Eugène Couleru-Meuri, son of famed watchmaker Charles Couleru-Meuri, in July 1923. It was used for an 8-day clock, and this was acquired by Ernest Tolck in 1927. Tolck had long been associated with 8-day clocks since he purchased the assets of Marc Dubois, which was itself successor to Léon-N. Robert and the family Robert-Bornand.

Numa Robert-Bornand was located at 149 Rue des Juifs in La Chaux-de-Fonds in 1850. This address was re-numbered to become 7 Rue des Juifs in 1859 and the street renamed Rue Fritz-Courvoisier by 1869. By 1871, the company was called Numa Robert-Bornand & Fils, and was simply Robert-Bornand & Fils between 1883 and 1889.

Another La Chaux-de-Fonds watchmaker, Charles Couleru-Meuri, was located at 9 Rue Neuve as early as 1880. He won a bronze medal at the Paris exposition in 1889. In 1894 Couleru-Meuri had relocated to a large factory at 18 Boulevard du Petit-Château opposite Léon Breitling's shop. By 1901, this was listed as 1 Rue Montbrillant. Couleru-Meuri was producing 8-day clocks under the "Octo" brand by 1908. These were advertised as non magnétique and featured an opening in the dial with a pointer at 6:00 showing power remaining. The patent No. 28536-37 is listed.

Léon-N. Robert succeeded Robert-Bornand et Fils and took over the factory at 7 Rue Fritz-Courvoisier. He was active there from 1892 to 1901 but relocated the factory to 8 Rue Jacob Brandt in 1908. He was succeeded by Marc Dubois by 1913, with Dubois taking over the Rue Jacob Brandt factory and producing 8-day clocks "pour automobiles et voitures" under the "Octo" brand by 1913. The factory also specialized in "petites Montres" or ladies bracelet watches using an 8 ligne movement. Both were advertised as "soignée" or "neat".

Couleru-Meuri was succeeded by Eug. Couleru by 1916. This firm produced Octo watches for Marc Dubois and was located at 37 Rue de la Charrière. Couleru was still associated with the Octo brand by 1927, having relocated to 19 Tourelles along with Ernest Tolck.

Ulysse Tolck in Fleurier

Henri Ulysse Tolck began as a watchmaker in Fleurier. By 1848 he was producing a few different pocket watches, including an 8-day model. For this reason, the later Montres Octo SA claimed to have been founded in the 19th century, though the firm chose 1858 as its founding date.

After his death, Henri Ulysse's son, also named Henri-Ulysse but commonly called Ulysse Tolck, took over the business, operating under the name U. Tolck & Co. In 1871, Ulysse Tolck was listed as having worked in Geneva but now located in Fleurier and able to produce many types of complications. He acquired a business in Paris in 1872 and began fitting watch crystals. He also formed a venture with a watch dial maker in Fleurier. In 1873, Tolck developed a watch later known as the Carosse, which was used to time the speed of racing.

In the initial survey of businesses in 1883, Ulysse Tolck of Fleurier (who then lived in La Côte-aux-Fées) is listed as a watchmaker and seller of ice and coal. He gave up this business to focus on watchmaking in 1888. Ulysse Tolck was divorced from his wife Louise-Adèle née Jequier in 1893. Tolck developed an octagonal watch case in 1898, placing an 8-day movement inside. The company was also producing specialized dashboard clocks for automobiles using this 8-day movement. Ulysse Tolck had died by July 1898, leaving the business to his son, Léon-Ernest "Ernest" Tolck.

Ernest Tolck in La Chaux-de-Fonds

Ernest Tolck took over his father's business on July 1, with the office at Rue de la Chapelle 4 in Fleurier. He quickly registered numerous brands incorporating Chinese characters and themes, indicating that he would focus on this lucrative market. Tolck would continue to register Chinese brands through the 1920s. Léon-Ernest Tolck (October 19, 1872-October 6, 1947) married Anna-Wilhelmine-Bertha "Berthy" Mädler (May 28, 1878-October 13, 1938).

In 1906, Ulysse's son Ernest Tolck relocated to the watchmaking city of La Chaux-de-Fonds. His office was registered along the main boulevard, Rue Léopold-Robert, at number 48 in June of that year. Tolck tried to diversify his interests at this time, joining a watch crystal operation in Monthoy known as La Valaisanne Fabrique de Verres de Montres as secretary, though he was quickly replaced.

Ernest Tolck's workshop was also listed at 19 Rue de la Paix, later relocating (after 1913) to 78 Rue Léopold Robert. Another Ulysse Tolck was listed as being active in Fleurier after this, suggesting that this firm was an extension or was unrelated. Another Tolck, Albert, worked in La Chaux-de-Fonds by 1901.

In September 1916, Tolck purchased the business of Marc Dubois, who had recently died. Thus he became listed as successor to Marc Dubois & Cie, occupying their factory at 8 Rue Jacob Brandt and taking over their Logic and Madu brands.

Tolck took out a two-page ad in Indicateur Davoine showing a line of 8-day clocks using the brand name Octo. These were dash, desk, and wall clocks "pour automobiles et voitures" and were also sold under the "Logic" name. Tolck also used the "Sincère", "Metropole", and "For-Ever" brands (as well as "Logic") for "petites montres" including wrist bracelet watches. These used an 8 ligne movement produced under the name Fabrique d'Horlogerie Soignée.

Ernest Tolck took over Eugène Couleru's Fabrique Octo following its 1927 bankruptcy. He removed the Marc Dubois name from the firm in 1934 as he focused more on the Octo brand, which he acquired in August of that year.

By 1928, Tolck was located at 19a Rue des Tourelles in La Chaux-de-Fonds. The company remained there to at least 1932.

Octo in Bienne

Ernest Tolck, Fabrique Octo was reorganized as a Société Anonyme called Ernest Tolck, Montres Octo Sàrl on August 31, 1941. This company was managed by Ernest Tolck himself and Robert Ducommun as minority investor and was located at Rue Léopold-Robert 49. Just two months later, on October 31, the company was purchased by Albert Etienne (?-December 5, 1957). Etienne, originally from Tramelan-Dessous, was an inventor and businessman who worked in Bienne and had invented a popular automobile fog light. Both Tolck and Ducommun left the board at this time.

Albert Etienne and his brother Marius-Albert moved the company to Bienne on April 20, 1942. It was originally headquartered at Mittelstrasse 17 but was moved to 4 Rue Adam Fr. Molz in September. The firm kept the Octo name but abandoned Tolck's. The Etienne brothers quickly raised 100,000 francs of share capital and added the assets of Montres Deto in May 1943. Marius was by far the minority partner, holding 1 share to Albert's 19.

Montres Octo moved on from the namesake 8-day wristwatch after World War II. Instead, Octo was a manufacturer of mid-priced wristwatches for the mass market.

The Octo range included the waterproof Lakemaster by 1958. The 1959 Basel Fair included the new Missilemaster. This waterproof antimagnetic watch featured an automatic calendar movement. It had a centrally-attached lug with an unusual look. Montres Octo celebrated its jubilee in 1959 with a range of gold plated watches.

Albert's son Marius Etienne took over the company between 1958 and 1963. Octo debuted the Skymaster line at the Basel Fair in 1963. between 1960 and 1962, Montres Octo relocated to 56 Rue de l'Avenir in Bienne-Ville.

The final appearance of the Octo brand came in 1965 when the firm created a novel flip-over watch known as the Compass. Although this anti-magnetic watch was ahead of its time, it failed to take hold and the firm soon ceased operations.
