Overview:
• Beyond the skeleton movement: Artistic openworking and sapphire bridges showcase the beauty of the caliber's 537 components.
• Ultra-slim caliber: High-complication automatic caliber, 4.7mm thick, case height 8.25mm, diameter 41.4mm.
• Complex case structure: A new case consisting of 60 components. The first specially designed case for Caliber 362, beautifully adapting the iconic Master Grande Tradition codes.
• The world's thinnest automatic minute repeater tourbillon: A fully integrated movement design where the minute repeater forms an essential element of the structure.
Jaeger-LeCoultre presents the Master Hybris Mechanica Ultra-Slim Minute Repeater Tourbillon, reinterpreting the Grande Maison's renowned ultra-slim calibers by fusing a minute repeater and a flying tourbillon. Housed in an 18K pink gold case, it is a mere 8.25mm thick. Structured to allow a view of the entire mechanism, the movement is revealed through the transparency of sapphire, and a dial stripped of decoration forms an openworked ring surrounding the movement. Utilizing 7 patented technologies, 6 of which were specially developed for the launch of Caliber 362 in 2014. This watch merges some of the most notable feats in watchmaking, including a one-minute flying tourbillon and a beautifully resonant minute repeater.
A Great Heritage: Watches with Chime Mechanisms, Ultra-Slim Calibers, and Timekeeping Precision
At the time of its unveiling in 2014, Caliber 362, embodying groundbreaking inventions and innovative aesthetics, inherited Jaeger-LeCoultre's outstanding legacy in two key areas: chiming mechanisms and precise timekeeping technology. It remains the world's thinnest automatic minute repeater tourbillon today.
Jaeger-LeCoultre's expertise in ultra-slim movements dates back to the collaboration between Jacques-David LeCoultre and Edmond Jaeger. This partnership resulted in the birth of Caliber 145 in 1907, boasting a record-breaking thinness of 1.38mm.
Since developing its first tourbillon movement in 1946 and launching its first tourbillon wristwatch in 1993, Jaeger-LeCoultre's pursuit of heightened timekeeping precision has led to numerous inventions in tourbillon cage structure and balance spring shape, optimized for various regulating organs.
Since introducing its first minute repeater in 1870, Jaeger-LeCoultre has produced over 200 different repeater calibers. The time and effort the Manufacture has poured into studying striking complications, sound quality, tone, volume, and rhythm have yielded numerous patents, some of which are incorporated into Caliber 362.
Rather than layering separate complications, Caliber 362 was conceived from the start as a fully integrated movement. The minute repeater is not added to a base caliber but forms an essential part of the structure itself. This integration is the foundation that achieves the movement's outstanding thinness.
The chiming mechanism was completely redesigned to minimize vertical space. Its optimized structure occupies about one-third of the entire caliber's volume, demonstrating how meticulously each component was calculated to reduce thickness without compromising acoustic performance. By rethinking the placement of the racks, hammers, and gongs within the mainplate, Jaeger-LeCoultre engineers eliminated the extra layers traditionally required for repeater mechanisms.
Equally contributing to this slim profile is the flying tourbillon, consisting of 59 components and weighing 0.248 grams. By omitting the upper bridge, the one-minute flying tourbillon keeps its structural height low while enhancing visual lightness. Removing the upper support not only heightens the beautiful transparency of the movement but also removes excess material, reducing vertical...
