In 1833 Antoine LeCoultre opened his factory in Le Sentier, located in the Valley de Joux Switzerland, and commenced manufacturing of watches. His development of new manufacturing tools and techniques pushed the watch making world into new boundaries of reality. Until this day many famous brands rely and utilize the movements of JLC (as it is affectionately called by its many fans). His motto was “We must base our experience on science.” The combination years later of Antoine’s grandson, David LeCoultre, who merged the company with Edmond Jaeger started the brand name Jaeger LeCoultre. Antoine LeCoultre changed the watch-making world forever with the invention of a new system of winding, where it was no longer necessary to use keys to rewind and set watches. He devised a pushbutton that triggered a lever to switch from one function to another with much less effort on the part of the owner. This established Jaeger LeCoultre watch company as the leading brand in user-friendliness. 1931 saw the birth of the Reverso watch collection originally created for polo players. Due to the extreme nature of the game, a player wearing a watch could easily be struck in the wrist with a club that would break the glass of a regular wristwatch. Therefore, JLC created the Reverso watch which would be able to flip around to an all metal backing thereby protecting the timepiece. Today the Reverso watches have evolved into having various features and complications on both sides of the watch. The Reverso watches remain one of the most recognizable watches in the world and a staple in every watch enthusiast’s collection. Reverso Classic Style watches include all time classics such as the Reverso Duo watch with dual time zones and the Reverso Grande Taille with a solid metal back, just like that of the original Reverso watch of 1931. The Reverso Classique and the Reverso ladies have a solid metal back and are available with either quartz or mechanical movements. The Reverso Series also has a whole collection of ladies watches with and without diamonds. These watches include: The Reverso Lady Mechanical, The Reverso Lady Quartz, Reverso Florale, Reverso Neva and Reverso Lena, Reverso Joaillerie, Reverso Duetto, Reverso Duetto Joaillerie, Reverso Duetto Duo, and Reverso Duetto Classique.

Two more limited series from Jaeger LeCoultre include the Memovox Tribute to Polaris 1965 and the 1833 Collection – Limited Edition. Jaeger LeCoultre subjects all of their watches through a most rigorous testing process, which far exceeds the highly regarded COSC testing process. Once the movements are completely cased as they would be utilized by the consumer, the watches are then submitted for an extremely rigorous, continuous 1000 hour test. Only after successfully passing this test will the watch be allowed to leave the factory. This ensures a very consistent and accurate timepiece distinguishing JLC from the rest.
