Antoine LeCoultre founded the workshop in 1833 and invented the millionomètre, the first instrument able to measure a micron. The company has produced well over a thousand distinct calibres and spent much of the 20th century supplying movements to other prestigious houses — including Patek Philippe, Audemars Piguet and Vacheron Constantin — which is why it is often called the watchmaker's watchmaker.
