The great Manufacture of the Joux Valley
Introduced to metal work at the family smithy, Antoine LeCoultre has a journey like no other - punctuated by groundbreaking inventions. His first invention? A machine designed for manufacturing cogs. This was followed by the millionometer in 1844: the most precise instrument to measure the micron. In 1847, he invents the first keyless watch - the key being replaced by a push button for winding and time setting.
In 1858, his son, Elie, joined the company at the age of 16. This was the start of a new era: exceptional industrialist, promoter of new manufacturing processes, creator of numerous calibers with complications, he transformed - in a matter of years - the family workshop into the first Vallée de Joux manufacture. In 1880, 500 employees worked for the manufacture, combining all the skills of watchmaking under one roof.
