In 1833, following his invention of a machine to cut watch pinions from steel,[9] Antoine LeCoultre (1803-1881) founded a small watchmaking workshop in Le Sentier, where he honed his horological skills to create high-quality timepieces.[10] In 1844, he invented the world’s most precise measuring instrument at the time, the Millionomètre, and in 1847 he created a keyless system to rewind and set watches. Four years later, he was awarded a gold medal for his work on timepiece precision and Mechanization at the first Universal Exhibition in London.
