In 2013, at the 180th anniversary of the brand’s founding, JAEGER-LECOULTRE launched the ultra-thin Master Ultra Thin Jubilée commemorative watch to express the founder of the watch factory Antoine LeCoultre Memorial. This masterpiece interprets extraordinary achievements in watchmaking technology, with a case thickness of only 4.05 mm, becoming one of the thinnest watches in its category. In 2014, the Master Ultra Thin series added a brand-new model-Master Ultra Thin 1907 ultra-thin master series watch, the new work combines outstanding mechanical performance and elegance in one, achieving a model of watch minimalism. It is worth mentioning that the new Master Ultra Thin 1907 series was first released in May in China, Hong Kong, Taiwan and South Korea’s Jaeger-LeCoultre stores.

The meeting of two great visionaries
At the beginning of the 19th century, the watchmaking pioneer Antoine LeCoultre brought together all the watchmaking techniques under the same roof and used machinery to make watch components to ensure high precision and interchangeability. A series of technological breakthroughs made this Ru Valley workshop famous and soon became known to the world for its high-quality, sturdy movement. This great initiative also inspired the two entrepreneurs at that time. Jacques-David LeCoultre and Edmond Jaeger worked closely to create a series of watches with both elegant appearance and superb craftsmanship. The precision of Swiss watchmaking combined with Parisian aesthetic luxury has been successfully proven. After less than two decades, the brand took the name of both parties and changed its name to JAEGER-LECOULTRE.
The entire twentieth century witnessed the fusion of bold innovation, prestigious reputation and precision and reliability, and the advent of the Master Ultra Thin series proved the undeniable strength of Jaeger-LeCoultre at the beginning of this new millennium.
The Master Ultra Thin 1907 watch is paired with an ultra-thin rose gold case, which is shaped like a blade, which makes it even slimmer. In order to realize the precious and thin size in each production stage, the mechanics and watchmakers of the Jaeger-LeCoultre watch factory carefully study each component of the movement and the case. However, the pursuit of detail does not detract from the beauty of the watch. The history of the watch factory originates from the city of light and the independent Ru Gu Valley. Jaeger-LeCoultre is loyal to history and knows that the art of watchmaking represents the achievement of technology and aesthetics. The Master Ultra Thin 1907 is the best articulator of minimalism: a 39 mm diameter case that fits perfectly on any size wrist. Such a delicate size requires Jaeger-LeCoultre watchmakers to design and create an advanced watch movement that can be carried in a slim case, which is undoubtedly a higher technical feat.
Refined and elegant, technical achievements
The Jaeger-LeCoultre 849 manual winding movement is exquisite and meticulous, which can be described as a miracle. The entire process from production, assembly to decoration is completed by hand by the watchmaker’s complex watchmaking workshop. This movement consists of 123 parts, with a power reserve of up to 35 hours, and a balance wheel that oscillates at an average frequency of 21,600 vibrations per hour. At the same time, the watch follows the tradition of great watchmaking, using the central hour and minute hands, and is equipped with a Jaeger-LeCoultre movement with a thickness of just 1.85 mm to achieve the acclaimed precision timepiece.
The dial of the watch fully reflects the minimalist aesthetics of the watch. The two crown-like hands on the white grained dial slide smoothly and are embellished with Barton-type hour markers. Rose gold minute dots accent the hour markers, and the Jaeger-LeCoultre logo ‘JL’ at 12 o’clock. After careful craftsmanship, the lines are concise and clear, showing the essence of the watch, which can only be achieved by a true master watchmaker.
