Jaeger Le Coultre Clocks

Antique Jaeger Le Coultre Clocks

Today, the Jaeger-LeCoultre Reverso is one of the most famous watches ever produced. The company got its start producing clock parts for other companies in addition to producing movements for its own watches. In the early part of the 20th Century, Jaeger-LeCoultre even supplied movements to the great firm of Patek Philippe. Then as now, Jaeger-LeCoultre was considered one of the finest watchmakers and clock makers in Switzerland.

In 1833 thirty-year-old Antoine LeCoultre, son of Vallee de Joux watchmaker Jacques LeCoultre, opened a small factory in the town of Le Sentier. The current Jaeger-LeCoultre factory is only a few feet away from the site of the original factory. LeCoultre soon proved himself to be a gifted watchmaker, but an even more brilliant inventor. In 1844, LeCoultre revolutionized the watch industry with the invention of the millionometer, an instrument which could be used to performe measurements of up to one thousandths of a millimeter accurately. As a result, precisely finished components could be manufactured, resulting in greatly improved accuracy in timekeeping.

In 1925, the grandson of the firm's founder, David LeCoultre, merged his company with that of Edmond Jaeger, the exclusive supplier of watch movements to Cartier. This is when the modern company known as Jaeger-LeCoultre first came into existence. Up to this point, Jaeger-LeCoultre had not sold any watches under its own name. The merger, however, prompted further technical innovations, not the least of which was a case made from stainless steel, as well as the creation of the smallest mechanical movement in the world, which weighed less than one gram.

The Founding of the 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.

Nineteenth Century Achievements

1847 Invention of the crown winding system.
1851 Gold medal at the Universal Exposition in London.
1867 LeCoultre becomes the first Manufacture in the Vallée de Joux.
1890 The Manufacture makes 125 simple calibers and 31 complicated calibers.

A 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.

A 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.

Twentieth Century Achievements
Out of the two men's friendship was to emerge one of the most beautiful collections of ultra-thin pocket watches, followed by other creations that would culminate in the Jaeger-LeCoultre brand.[7] In 1907 the JLC Caliber 145 set the record for the thinnest movement at 1.38 mm.[8] However, there were many other achievements of Jaeger-LeCoultre:
