Haas Neveux & Cie., Geneva, is one of the oldest watch manufacturers in Switzerland.  While they devoted a great deal of attention to the style of their watches, they also always remained at the forefront of the construction of high-precision movements.  In 1896 they produced a manually wound calibre that was only 2 millimetres high and in 1914 Haas Neveux won a Grand Prix at the National Exhibition in Berne for its elegant watches for men and women.
