This dark blue bi-dimensional three-axis tourbillon watch, with elegant hands running upstream of the dark blue dial, and rectangular cut diamonds surrounding the case, perfectly interprets Jaeger-LeCoultre’s extraordinary watchmaking craftsmanship.
180 years of complex function creation, 180 years of creative spirit, 180 years of passion. From Antoine LeCoultre to generations of watchmakers, they have passed on the spirit of the Jaeger-LeCoultre and continue to write a new chapter in the legend of watchmaking. In the past ten years, the Jaeger-LeCoultre watchmaking factory, which is a model of the Swiss fine watchmaking industry, has demonstrated outstanding creativity and created many technical achievements with a long tradition and ingenious craftsmanship, which has written the 21st century The most outstanding page in the field of horological complications.
An innovative masterpiece, the Duomètre Sphérotourbillon watch combines unparalleled mechanical performance, elegance and superior complexity to meet the expectations of the most discerning watch enthusiast and collector. The master watchmaker and the jewellery master cooperated to show the new work of the Grande Complication large-scale complication series with the excellence of handicraft skills.

Fine Watchmaking and Fine Jewellery
A rectangular cut diamond surrounds the white gold case, and the Duomètre Sphérotourbillon Blue watch is paired with a dark blue dial to present a variety of light and shadow effects, showing the ultimate beauty of complex functions. The flying three-dimensional dual-axis tourbillon staged a fascinating visual feast. The window at 9 o’clock on the side of the case allows a glimpse of the tourbillon’s elegant dance. The two separate areas of the dial reflect the revolutionary Dual-Wing design concept, while the baguette-cut diamonds highlight the double magic. The stones on the left side of the dial are arranged in a fan shape, surrounded by a window showing the secret of the three-dimensional tourbillon, showing the charming Art Deco style. The cleverly arranged main dial is visible on the right side of the dial, and the local time and date indication is located at the lower position, which is easy to read. Another 24-hour small dial occupies the top of the dial, showing the time in the second time zone. The small second hand is located below the dial. The blue gold sandstone paved on the inside and outside of the small dial is sparkling, showing a strong contrast between the different functions of the watch.
The Dual-Wing design concept allows Jaeger-LeCoultre watchmakers to create the first tourbillon that can be precisely adjusted. The diamond-studded button at 2 o’clock can reset the small seconds hand under the tourbillon to complete the flyback timing function. The feature of the flyback chronograph function is that the operation of the adjustment mechanism is not stopped, the small second hand returns to zero, and it immediately resumes operation, thereby maintaining the watch’s maximum accuracy.
Caliber 382, the epitome of watchmaking
This watch carefully retains the aesthetic design of the Duomètre series. The complicated gem setting process and the intricate movement structure contrast with each other. To make everyone happy, the watch’s transparent caseback reveals the decorative back and perfectly presents the 382 movement, which is completely assembled and decorated by hand. The fine processing on the unprocessed nickel-silver semi-finished movement reinforces the uniqueness of the Duomètre Sphérotourbillon bi-wing three-dimensional tourbillon watch. Jaeger-LeCoultre’s signature radial stripe decoration (côtes soleillées), beautiful lines of concave and convex angles, various shapes are intertwined and harmonious: the aesthetic design of the Jaeger-LeCoultre 382 movement fully reflects the high level of clock art.
Jaeger-LeCoultre’s gem setting technique
Traditional gem setting is a craft that uses gems to make decorative arts shine. In the mechanical setting process, the craftsman only needs to place the gemstone into the machined mounting base, and then let the inlay cover the gemstone and fix it. The traditional gem setting process is very different. The professional setting master must first determine the number of gems and their placement in advance, and then create two independent holes: the first hole is extremely fine to determine the gem Accurate setting position, another hole is used to enlarge the first hole to the size of each gem. In the long and arduous process, the jeweler must carefully cut and cut the inserts repeatedly to gradually shape the precious metal claws that hold the gemstones. Then, the jeweler needs to carefully adjust the setting position of the gemstone with extremely sophisticated skills. Exquisite craftsmanship has made each piece a truly unique treasure. Even if it is made into thousands of similar items, it is impossible to find exactly the same works. Square diamond inlays are suitable for angle-cut gems such as square, rectangular or trapezoidal. A square diamond inserter also follows the above steps. The obvious difference is that this process requires a longer manual operation to place each gemstone in the base or setting.
