Perfect Modern Design The Jaeger-LeCoultre Master Ultra Thin Collection
For over a century,Jaeger-LeCoultre watchmanufacture has held a special passion for the creation of ultra-thin mechanical movements. The brand's Master Ultra Thin collection is slender, minimalist and full of distinct personality.

With delicate design and exceptional technology, new materials give this watch a fresh look. Following the existing sophisticated rose gold version, the Master Ultra Thin Tourbillon is now introduced in white gold, combining elegant character with modern aesthetics.The design of the Master Ultra Thin Tourbillon draws inspiration from the most glorious era in watchmaking. Dauphine hands exude a classic traditional feel, adding a refined and elegant touch to the watch's minimalist design. The white gold case paired with a white grained dial gives the overall timepiece a more harmonious and balanced appearance, offering a fresh sensation. The precious yet minimalist white gold material highlights the slender lines of the lugs while making the case even thinner. Nickel-plated black hands and hour markers attest to the watch's modern style, showcasing a unique urban charm.
Crafted in-house by the Jaeger-LeCoultre manufacture, the tourbillon positioned at 6 o'clock immediately draws the eye. This signature Jaeger-LeCoultre complication offsets the effects of gravity on the regulating organ, ensuring precise and reliable timekeeping. Crafting a tourbillon requires exceptionally meticulous craftsmanship, creating a spectacular sight on the dial. A filigree bridge carries the tourbillon, operating on a proportionally balanced track. The tourbillon carriage is crafted from grade 5 titanium, achieving extreme lightness with a total weight of only 0.33 grams, effectively reducing the energy consumed by the barrel. The barrel is wound via ceramic ball bearings. Such a highly sophisticated mechanism boasts a fascinating structure, made all the more delightful against the pure dial.

Through the sapphire crystal case back, the rhythmic beauty of the Jaeger-LeCoultre Calibre 982 mechanical movement can be admired. Operating at a frequency of 28,800 vibrations per hour, behind its unassuming exterior this watch not only perfectly meets the rigorous quality standards of the Jaeger-LeCoultre manufacture, but also encapsulates decades of essence in precision timekeeping and technical research. The case measures 40 mm in diameter and a mere 11.30 mm in thickness, making it suitable for everyday wear. The tourbillon ensures accurate and reliable running, alongside a fully featured and easily operated automatic mechanical movement, making this timepiece a coveted wrist treasure.

Black symbolises a continuous flow of energy and vitality, and has also served as a subject for great artists of the 20 century, pushing the boundaries of imagination to create master-level works. The Master Ultra Thin Moon pairs a black dial with a bold and daring attitude to express personal style.
Black is never ostentatious, and its unassuming vibe perfectly complements the pure lines of the Master Ultra Thin collection. Stepping outside the box, Jaeger-LeCoultre has discarded the conventional white and light grey dials. The new Master Ultra Thin Moon adopts black elements; the dial is not a simple matte black, but is decorated with sunray-brushed finishing to present a unique texture. The ultra-thin case and the minimalist lines of the watch complement one another, with various aesthetic designs balancing each other without any affectation.
This year, Jaeger-LeCoultre takes the celestial vault as its theme, highlighting the brand's exceptional craftsmanship and continuous pursuit of innovation and dream-chasing. Among various complications, the moon phase display possesses a unique charm that sparks the imagination. The Manufacture enhances the watch's contemporary personality through the moon phase display. The royal blue moon phase disc is adorned with a golden moon motif, creating a striking contrast with the pitch-black dial.The clear and legible date display is set on a ring concentric with the moon phase disc, framing the charming moon phase indication. In Jaeger-LeCoultre's watchmaking tradition, aesthetic beauty and practical function are inseparable, as watches are created for life, dreams and utility.

The date window is positioned at the 6 o'clock position on the dial, displaying the date via a rotating disc; its discreet nature perfectly matches the minimalist aesthetics of the overall watch. The newly launched stainless steel Master Ultra Thin Date this year is bound to become a model of timeless elegance.
