Bar turning in the Arve Valley
From the beginning, bar turning in the Arve Valley has been serving two sectors:
At the end of the 19th century and at the start of the 20th century, Geneva watchmakers gave parts to peasants from the valley to assemble during the winter months. Although very busy in the summer, these mountain peasants lacked work in the winter. Working for neighbouring Swiss watchmakers topped up their income.
At the Cluses market every Monday was dedicated to trade exchanges: the peasants brought their assembled parts and took away new parts for the upcoming weeks. The peasants gradually started to make their own parts to assemble, first of all in their barns and then in workshops.
At the start of the 20th century, someone from Cluses, inspired by a machine that he discovered in a fair in Nuremberg, designed his own machine to make screws and nuts. This is how the manufacturing of small assembly parts started, firstly for bicycles, then for cars and electrical appliances, from the 1920s to the 1950s.
