Haas – B. Jeune & Cie. (1870-circa 1885). Paris, Genève, Besançon. One of the oldest manufacturers of Switzerland, known for high-quality watchmaking. Haas Neveux & Cie. succeeded in the firm B. Haas, which was created in 1848. Haas Neveux & Cie. created the revolutionary extra flat watch with a winding mechanism. The firm sought to make their watches more elegant by making them flatter. At the 1896 Geneva Exhibition, they showed the first extra flat watch with a movement only two millimetres thick. While they devoted a great deal of attention to the decoration of their watches, in the form of pendants, bracelets, rings, etc., Haas Neveux & Cie. remained at the forefront of the making of high-precision chronometers, obtaining prizes at the Geneva Observatory competitions. Since its foundation, Haas Neveux & Cie. has won the highest prizes at international exhibitions.
