Ακαδημαϊκά:
Βetween 1870 and 1900, the Jaeger-LeCoultreα created no less than 128 different chronograph calibres! 42 were equipped with counters, 32 with split-seconds hands; 33 also comprised a repeater mechanism, and 1 combined a chronograph, a repeater and a perpetual calendar.
These calibres at one time supplied the entire Swiss, French and German watch industries, from Glashütte to Geneva and including Schaffhausen, Besançon, La Chaux-de-Fonds, le Locle, Saint-Imier, Fleurier, Sainte-Croix, and of course the Vallée de Joux.
The Manufacture Lecoultre & Cie had become a reference in the field of chronographs movements.
During the first half of the 20th century, the Manufacture continued to innovate in this field. From 1903 onwards, it began creating ultra-thin chronographs, which were marvels of technical sophistication and miniaturisation.

From the 1920s on, LeCoultre was one of the pioneers in chronograph calibres for wristwatches. By way of example, a LeCoultre 13-lignes movement made in 1923 Cal 13cc was fitted within a Patek Philippe watch that was estimated to be worth $200,000 at an auction in 1997.
