Jacques Jaeger Presents Three New Duomètre Watches

Jaeger-LeCoultre Duomètre Sphérotourbillon series three-dimensional biaxial tourbillon watch, Duomètre Chronographe chronograph watch and Duomètre Quantième Lunaire moon phase calendar watch are combined with innovative design features, exuding elegant and exquisite atmosphere. All three masterpieces feature opal-decorated magnet grey dials, and their deep shades are all men’s charms.
Duomètre Sphérotourbillon watch
   The new Jaeger-LeCoultre Duomètre Sphérotourbillon series of three-dimensional dual-axis tourbillon watches combines outstanding design, unique functions and exquisite elements contained in pure horological tradition. This large complication watch combines excellent technical performance, simple aesthetic design and extraordinary complex clock functions.

Sphérotourbillon spherical tourbillon: precisely adjustable tourbillon
   ‘Precision’ is the core of the Dual-Wing design concept. The master watchmaker of Jaeger-LeCoultre has always taken this as the concept when he conceived the Duomètre Sphérotourbillon series three-dimensional dual-axis tourbillon watch. In fact, only a few tourbillon watches have a clear seconds display, and even fewer can stop the seconds. The Dual-Wing design concept allows Jaeger-LeCoultre watchmakers to create the first tourbillon that can be precisely adjusted. At 2 o’clock, there is a button to return the small seconds hand to the bottom of the tourbillon. As a major feature, the flyback function does not affect the operation of the adjustment mechanism. The small second hand returns to zero and immediately resumes operation. Therefore, even when setting the watch time, the watch can still maintain the maximum accuracy, accurate to the second.
Multi-axis tourbillon
   This watch is the fourth masterpiece of the Duomètre series. In addition to its unmatched reliability, another striking feature is its tourbillon. Originally designed for pocket watches, the traditional tourbillon cannot offset the effect of gravity on the ground when it is in different positions. Therefore, an additional rotation axis must be added to achieve three-dimensional three-dimensional rotation, so that the tourbillon of the watch can function in different positions. Through the hollow dial, the wearer can enjoy the extraordinary sight of the tourbillon as it rotates. In addition to rotating around the titanium tourbillon frame axis, the tourbillon rotates around the second axis at an angle of 20 °. These two very different fast rotations (30 and 15 seconds respectively) keep the watch from being affected by gravity in different positions.
   The innovative technologies that Jaeger-LeCoultre won in the first astronomical timepiece of the 21st century are all displayed on this gorgeous tourbillon: the one-piece titanium tourbillon frame is light and precise; the cylindrical hairspring has two end curves for concentric back and forth movement The traditional hairspring is incomparable. In addition, the highly inertia balance wheel vibrates at a frequency of 21,600 times per hour, while the eyebolt sleeve protects the watch from vibration or impact through the screw locking system. The watch has a transparent caseback, and the details of the Model 382 mechanical movement manually assembled and decorated by Jaeger-LeCoultre are pleasing to the eye.
Seeing beauty in complex details
   This watch is equipped with many complex and sophisticated technologies, but its beauty is not diminished. The spirit of innovation is combined with the design concept of the former pocket watch, which highlights the elegance and exquisite style. The watchmaker’s fine processing on the unprocessed nickel-silver semi-finished movement has created the extraordinary charm of the Duomètre Sphérotourbillon series three-dimensional biaxial tourbillon watch. The movement uses Jaeger-LeCoultre’s signature solar radial pattern and sharp concave-convex sharp corners. The various forms are intertwined with each other in harmony. The aesthetic design of the Jaeger-LeCoultre 382 mechanical movement fully reflects the high level of watchmaking art.
   This watch follows harmonious proportions and adheres to the tradition of watchmaking-the delicate and delicate rose gold case, the dial is simple and legible, the bezel and lugs are polished, and the case hoop is polished. These iconic designs inherit the design aesthetics of the Duomètre watch series and contrast with the complex mechanical structure of the mechanical movement.
   The Dual-Wing design concept is reflected in two different areas of the dial: the Sphérotourbillon spherical tourbillon is openly displayed on the left, and the main dial displays the local time on the right, and the date display is cleverly surrounded. In addition, there is a 24-hour sub-dial above the dial to display the time in the second time zone; the small second hand is below the dial.
Duomètre Chronographe
   When designing the first Duomètre watch, how to create a watch with accuracy comparable to an astronomical watch is the biggest challenge facing Jaeger-LeCoultre watchmakers. The Dual-Wing design concept makes everything easy.
   The Jaeger-LeCoultre workshop decided to equip the first Duomètre watch with a chronograph function, and Duomètre Chronographe was born. With its unique style and excellent craftsmanship, it has become one of the finest examples of watchmaking art. The Jaeger-LeCoultre 380 mechanical movement is equipped with a new structure. Its biggest advantage is that the time display is as accurate as an astronomical watch.

   According to the Dual-Wing double-wing design concept, the first gear set is completely used for time display (hours, minutes, and seconds), and the second gear set is dedicated to timing functions, and at the same time has an adjustment accuracy of one-sixth of a second Blinking seconds hand. Both mechanisms are powered by their respective barrels, ensuring a 50-hour power reserve (time display of 50 hours and timekeeping function of 50 hours). Power transmission does not interfere with each other. To ensure an elegant appearance and ease of use, the same crown can be wound on two barrels: clockwise for time display and counter-clockwise for timekeeping.
   This Duomètre watch with a mechanical movement 380 is the first chronograph to start or stop the chronograph without a clutch. A unique button synchronizes the five timers perfectly. The Duomètre watch recreates a great watchmaking classic with its welded lug case, opal-coated magnet grey dial, and the Dual-Wing’s signature 380 mechanical movement.
Duomètre Quantième Lunaire Moon Phase Watch
   In classic watches, the sophisticated functions of the sophisticated calendar display will definitely affect the accuracy of the time display. The Jaeger-LeCoultre watchmaker used the Dual-Wing design concept to achieve the perfect work, creating a calendar watch as accurate as an astronomical watch.
   On the elegant and easy-to-read dial, the hours, minutes, seconds, calendar display function and moon phase display together create the classic design of the Duomètre Quantième Lunaire biplane series moon phase calendar watch. Through the case, the wearer can see part of the 381 mechanical movement. This superb movement is based on the Dual-Wing design concept and has unprecedented accuracy. It is another model in the field of fine watchmaking.

Dual-Wing design concept: Pioneer movement
   Jaeger-LeCoultre uses the Duomètre double-wing series and its Dual-Wing design as the concept to create innovative masterpieces in the field of fine watchmaking. The mechanical movement adopts a new structure as a whole, bringing unprecedented new functions. With the birth of the Dual-Wing design concept, Jaeger-LeCoultre watchmakers finally solved the problem of complex mechanical movements. Since complex functions use part of the power provided by the barrel, this energy consumption can disrupt the continuous power supply of the tuning device. The adjustment device must be carefully adjusted to ensure that it operates as accurately as possible. The power transmitted from the barrel to the gear train and escapement needs to be very stable and regular to ensure that the watch moves accurately and reliably.
Power from two movements at the same time
   The Dual-Wing design concept is to separate the power source of the two through the complex functions and the barrel of the movement to ensure a stable power supply, which has brought a new revolution in the field of fine watchmaking. In 2007, Jaeger-LeCoultre launched the Duomètre Chronographe chronograph watch. This chronograph watch with the Dual-Wing design concept has the same precision as an astronomical watch, and its timing is accurate to a sixth of a second. Later, the brand used this concept to create the Duomètre Quantième Lunaire biplane series moon phase calendar watch and the Duomètre Sphérotourbillon biplane series stereo two-axis tourbillon watch.
