Jaeger-LeCoultre launches new products in the MASTER ULTRA THIN series

Posted by KS Chan on

The Jaeger-LeCoultre Master Ultra Thin series demonstrates the philosophy of combining superb craftsmanship with timeless aesthetics. In 2020, it will add a new model and launch the new Master Ultra Thin Tourbillon Moon. . The new timepiece combines two highly respected complex functions in watchmaking technology-moon phase and tourbillon, which is the first time in the long history of the large workshop. In addition, it is also equipped with Jaeger-LeCoultre's iconic peripheral "instant jump" "Date display. This Master Ultra Thin Tourbillon Moon is equipped with a new self-winding calibre 983.

The tourbillon was born in the early 19th century to offset the adverse effects of gravity on the escapement mechanism of pocket watches, thereby improving the accuracy of pocket watches. In the 20th century, as pocket watches were replaced by wristwatches, the tourbillon was gradually forgotten. In 1946, in order to continue to explore the accuracy of travel time, Jaeger-LeCoultre designed the 170-type tourbillon movement. The movement is mounted in a pocket watch and is specially designed for timekeeping testing. In 1948, this movement won the first prize in the Centennial Competition of the Neuchâtel Observatory, and then won multiple awards in the 1950s. In 1993, when the tourbillon watch was still very rare, Jaeger-LeCoultre launched the first Reverso series tourbillon watch, equipped with a rectangular 828 movement. Further exploration and research have brought Jaeger-LeCoultre tourbillon technology to a whole new level. In 2004, the spherical dual-axis tourbillon was invented, and the Jaeger-LeCoultre Gyrotourbillon 1 spherical tourbillon watch came into being.

In 2009, Jaeger-LeCoultre launched the Master Tourbillon series of tourbillon watches. The 978-type movement onboard won the first prize in the International Astronomical Timing Competition held by Le Locle Museum in Switzerland. Since then, this movement has become the backbone of the Jaeger-LeCoultre tourbillon movement, and in 2019 it has undergone a disruptive and innovative design with a new high-end finishing.

Jaeger-LeCoultre engineers developed a new calibre 983 for the Master Ultra Thin Tourbillon Moon based on calibre 978, adding moon phase and "instant jump" date complications.

The triple moon phase indicator that displays the moon age and the moon phases in the northern and southern hemispheres is also a recent research and development result of Daefang, which was officially incorporated into the movement function last year. The new 983 movement has a frequency of 28,800 vibrations per hour (4 Hz) and a power reserve of 45 hours.

The Master Ultra Thin Tourbillon Moon is equipped with a Le Grand Rose gold case. This new rose gold alloy material was launched this year, showing a layered shining luster that will last forever. Adhering to the classic and elegant design elements of the Master Ultra Thin series, the case is fully polished, with long chamfered lugs and a slim bezel.

The eggshell white dial complements the warm rose gold color, understated by the moon phase display and tourbillon. The shape of the crown princess hands and the slender arrow-shaped inlaid gold hour markers echo each other, making them more delicate and delicate. If you look carefully, you can find that, according to its different positions on the dial, the outline of each hour marker is slightly different, and important details are marked in red to make the reading more clear and accurate.

The astronomical complication of the northern hemisphere moon phases displayed in the traditional way is located on the upper part of the dial, and the polished golden disk representing the moon stands out against the backdrop of the dark blue night sky with shining stars. On the left and right are the circle with the moon phases of the southern hemisphere and the moon age display, both of which are indicated by a double-headed pointer.

The engineers of DaWorkshop also incorporated Jaeger-LeCoultre’s iconic "instant jump" complications into the peripheral date display. When transitioning from the 15th to the 16th of each month, the date hand will automatically jump 90 degrees to avoid obstructing the moon phase display.

The protagonist in the lower half of the dial is the tourbillon. The titanium tourbillon frame (all parts weighing approximately 0.3 grams) fixed in the newly designed polished rose gold watch bridge rotates once every 60 seconds. The slim tourbillon bridge and the large display window help light penetrate the dial and make the structure more transparent, so that the exquisite mechanical mechanism is unobstructed.

The long-span hollow tourbillon bridge on the back of the watch further enhances this sense of transparency. The Geneva wave pattern on it echoes the sun-ray pattern on the main bridge. The hollow rose gold winding rotor decorated with the JL logo is decorated with alternating polishing and micro-sandblasting on the surface, which is more concise and flexible. Other exquisite decorations include blue steel screws, round grained patterns and chamfered bridges.

Like all Jaeger-LeCoultre timepieces, the Master Ultra Thin Tourbillon Moon comes with an eight-year international warranty and has passed one of the most stringent testing procedures in the watchmaking industry: the Jaeger-LeCoultre "1000-hour test" Certification.
