The Jaeger-LeCoultre Gyrotourbillon 1, the first spherical multi-axis tourbillon wristwatch in history, was introduced in 2004 and was created by master watchmaker Eric Coudray in partnership with famed designer Magali Métrailler. A multi-axis tourbillon, a perpetual calendar with retrograde date, month, and leap year indications, and an equation of time display that illustrates the difference between solar and mean time are just a few of the amazing complications housed within this remarkable timepiece. The watch's remarkable 8-day power reserve, which is powered by twin barrels, highlights its technical prowess.
At the heart of the watch lies the Caliber 177, a movement developed entirely from the ground up to accommodate the revolutionary tourbillon. Instead of modifying an existing mechanism, Jaeger-LeCoultre used sophisticated simulation technology to create a system that was precisely balanced across all of its delicate parts and perpendicular axes. The Gyrotourbillon is made up of 679 parts and has two concentric cages. The outer cage rotates once every 60 seconds, and the inner cage, which holds the escapement, hairspring, and balance wheel, rotates once every 24 seconds, for a total of 2.5 rotations per minute. This clever design ensures unmatched chronometric precision by reducing positional errors caused by gravity.
The tourbillon carriage, which weighs only 0.336 grams despite having 90 parts, is a prime example of Jaeger-LeCoultre's ability to combine mechanical brilliance with aesthetic elegance. In addition to being a significant milestone in the brand's history, the Gyrotourbillon 1 is still regarded as a pivotal accomplishment in the development of modern watchmaking.
