Do You Know Jaeger-lecoultre?

Jaeger-lecoultre was founded by Antoine LeCoultre.

The correct answer is Gyrotourbillon I. In 2004, the Manufacture created its first grande complication wristwatch called the Gyrotourbillon I. This watch features a tourbillon that gravitates on two axes, along with a perpetual calendar with double retrograde indicators and a running equation of time.

LeCoultre created a keyless system in 1847, which indicates that this system was used for a specific purpose. Among the given options, the most logical and relevant use for a keyless system would be to rewind and set watches. This suggests that LeCoultre's keyless system was designed to make it easier and more efficient to wind and set watches without the need for a traditional key.

Jaeger-LeCoultre was officially renamed in 1937. This means that before 1937, the company had a different name. The other options (1978, 1986, 1967) are not correct because they are after 1937, which is the correct year for the renaming.

In 1958, Jaeger-LeCoultre created a watch to commemorate the International Geophysical year. This watch was designed to be protected against three elements: magnetic fields, water, and shocks. The inclusion of magnetic field protection is important as it ensures the watch's accuracy and reliability in environments where magnetic fields may be present. Water resistance is essential to prevent damage to the watch when exposed to water or moisture. Finally, shock resistance ensures that the watch can withstand physical impacts and vibrations without affecting its functionality.
