The Jaeger LeCoultre Micrometer

In 1844, LeCoultre measured the micron (μ) for the first time; he created the world's most precise measuring instrument, the millionometer (a device capable of measuring to the nearest thousandths of a millimeter).

Jaeger LeCoultres' Keyless Works

In 1847, LeCoultre created a revolutionary system that eliminated the need for keys to rewind and set watches. A push-piece activated a lever to change from one function to another.

Jaeger LeCoultres' Early Awards & Recognition

In 1851 at the first Universal Exhibition in London, LeCoultre was awarded a gold medal in recognition of his collective works in the fields of precision and mechanization.

The Founding of Jaeger LeCoultre Manufacture

Elie LeCoultre, Antoine's son understood that it was necessary to control all the different stages of manufacturing and assembly. In 1866 he transformed his workshop into a 'Manufacture'. Under one roof, his employees were to pool their know-how, enabling them to meet the most incredible challenges. In 1870 LeCoultre & Cie manufactured the components of complicated movements using mechanized processes. Within 30 years, thanks to the marriage of hand and machine, the Manufacture created more than 350 different calibers of which 128 were equipped with chronograph functions and 99 with repeater mechanisms. Today the original workshop has expanded into an all inclusive manufacturing facility, able to produce all components required for a Jaeger-LeCoultre timepiece. Recently, construction has begun to expanded the workshop even further. Jaeger-LeCoultre continues to produce luxury timepieces that pass the test of time and are considered by connoisseurs to be among the very best in the world.

Jaeger LeCoultres' relationship with Patek Philippe

From 1902 and for the next 30 years, LeCoultre & Cie produced most of the movement blanks for Patek Philippe of Geneva.

The Coming Together of Jaeger & LeCoultre

In 1903, the Parisian Edmond Jaeger challenged the Swiss to manufacture ultra-thin calibers of his own design. Jacques-David LeCoultre, grandson of Antoine undertook the challenge.

Jaeger LeCoultres' relationship with Cartier

Cartier, a client of Edmond Jaeger for several years signed an exclusive contract with the Parisian watchmaker in 1907 under which agreement Jaeger, LeCoultre & Cie crafted the stunning watch creations of Cartier.
