Edmond Jaeger french watchmaker and specialist in fine micro-engineering, devoted his life to developing mechanisms to measure speed: chronographs, tachometers, kinemometers and counters used in aviation, shipping and automobiles. He was co-founder of Jaeger-LeCoultre brand.
Jaeger-LeCoultre is a high-end luxurywatch and clock manufacturer founded in 1833 by Antonie LeCoultre. In 1833, Antoine LeCoultre founded a smallworkshop in Le Sentier, Switzerland, for the manufacture of high-quality timepieces.In 1844, he measured the micrometre (μm) for the first time and created the world's most precise measuring instrument, the millionometer, capable of measuring to thousandths of a millimetre.In 1847, LeCoultre developed a system that eliminated the need for keys to rewind and set watches, using a push-piece that activated a lever to change from one function to another.In 1851,he was awarded a gold medal for his work on time piece precision and mechanization at the first Universal Exhibition in London. In 1903, Parisian Edmond Jaeger challenged Jacques-David LeCoultre, grandson of Antoine, to manufacture ultra-thin calibers of his design. Out of their relationship emerged a collectionof ultra-thin pocket watches, followed by others that eventually, in 1937, officially culminated in the Jaeger-LeCoultre brand.
