Launched in 2004 Jaeger-LeCoultre’s Gyrotourbillon 1 wristwatch is a stellar complication timepiece developed by master watchmaker Eric Coudray and designer Magali Metrailler. The caliber 177 is composed of 679 individual parts, 117 jewels and features an array of complications including a multi-axis tourbillon, perpetual calendar with retrograde date sector and month and leap year indication. In addition, its movement provides eight days of power reserve and features a "running" equation of time indication that displays the difference between solar time and mean time. Solar time is indicated by the minute hand tipped with a small sun, which sometimes runs ahead or behind the minute hand. Both hands are synchronized four times a year.

With its introduction, it allowed the Jaeger-LeCoultre to become not just a haute horlogerie brand, it elevated the brand into a haute horlogerie movement maker. At the time of its release, there were few if any multi-axis tourbillon watches offered on the market. This amazing technical advancement was constructed of two carriages on two axis and different timing, with the external rotating every 60 seconds and the internal every 24 seconds, completing 2.5 turns per minute, thus allowing for correction of gravitational errors in all positions. The speed and continuous motion of the spherical tourbillon display will absolutely mesmerize and fascinate its wearer.

The present example, no. 33 in the series of just 75 timepieces, is in excellent condition and accompanied with its original certificate of origin and presentation box. When it was first released, the Gyrotourbillon 1 was the most complicated watch made by Jaeger-LeCoultre. It pushed the boundaries of mechanical watchmaking and opened the door for a new era of complicated timepieces that are not only visually stimulating, but also technical marvels that are a joy to contemplate.
