What is the grade of Jaeger-LeCoultre watches?
Chronographe Rétrograde was launched in 1996, bringing Reverso's various styles to the extreme. The front of the watch is used to display the time; the back is a chronograph stopwatch equipped with a 30-minute retrograde chronograph device. The Reverso three-sided watch launched today has completely subverted the public’s concept of watches. This is the only classic flip watch that can present three different dials on one watch. And only those Jaeger-LeCoultre watch factories with decades of experience in the complex watchmaking industry, after more than three years of continuous research and development, can today's epoch-making product come out. Accurately distinguishing time from time is the most precious treasure of human beings, and our daily work is governed by time. Because of this, people always try to grasp time and persistently try to measure it in the most accurate way.
Clocks with minutes display function appeared at the end of the fifteenth century; seconds, the second smallest unit of minutes (secundadiminutivapars in Latin), did not appear until the late sixteenth century. The birth of the second hand marked the beginning of mankind's unremitting efforts in the field of timekeeping, enabling mechanical clocks to achieve the most accurate and reliable performance. Thanks to the development of navigation, leaps and bounds were achieved in the late Middle Ages due to the development of precise time. At that time, people were full of ambitions and thought it was a responsibility to go to sea and explore the world. The key to smooth sailing in waves is to accurately grasp the ship's position, so being able to accurately measure the time plays as important a role as the keel structure's ability to take in enough water.
A series of processes such as inlaying, glazing, engraving, and inlaying on the flag surface are a veritable treasure trove of talents in the Jaeger-LeCoultre watch factory. As the guardian of ancient craftsmanship, watchmakers carefully polish every piece of timepiece to make it a unique masterpiece.
