Jaeger-LeCoultre（積家）

In 1833, Antoine LeCoultre (1803–81) founded a small workshop 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 1870, LeCoultre began using mechanized processes to manufacture complicated timepiece movements. Within 30 years, LeCoultre had created more than 350 different timepiece calibers, of which 128 were equipped with chronograph functions and 99 with repeater mechanisms. In 1907, the LeCoultre Caliber 145 set the record for the thinnest movement at 1.38 mm. JLC began manufacturing the Atoms clock in 1936 after purchasing the patent from Jean-Leon Reutter, who invented it in 1928.

In 1937, Parisian Edmond Jaeger and Jacques-David LeCoultre, grandson of Antoine officially established the Jaeger-LeCoultre brand. In 1941, Jaeger-LeCoultre earned the highest distinction from the Neuchatel Observatory for its tourbillon Caliber 170. In 1982, the Jaeger-LeCoultre museum was established in Le Sentier. In 2009, JLC produced the world's most complicated wristwatch, the Hybris Mechanica a Grande Sonnerie with 26 complications.

With over 170 years’ hard work, Jaeger-LeCoultre brand is ranked No. 10 at the world’s best watch, owns over 200 patterns and known for the heritage from centuries.
