2013 Sihh – Jaeger-lecoultre Continued Unremitting Exploration Of Precision Tourbillon

The watchmakers of the Jaeger-LeCoultre watch factory have re-engineered their tourbillon frame without any compromise in terms of performance, reliability and robustness. This high-precision self-winding movement with a frequency of 28,800 vibrations per hour is equipped with a titanium tourbillon spinner. The newly designed oversized balance wheel has a swing inertia of 11.5 mg x cm2.

 The Master Tourbillon Dualtime watch is dated using Jaeger-LeCoultre patented two-way adjustment technology. At the same time, it can quickly jump from 15th to 16th to avoid blocking the titanium tourbillon frame. The subtle movements are all here.

 To meet the demanding requirements of daily wear, this outstanding MASTER TOURBILLON watch has passed 1000 hours of testing for accuracy, reliability and water resistance. This professional test involves the stability and amplitude of the tourbillon spinner, and how it behaves when subjected to a slight impact.

 Portable clocks appeared more than 500 years ago. Clocks, like automatic machines, were used as a tool for recreation. The pursuit of precision began after the social turmoil in the early 19th century. Time measurement is no longer just a hobby for the rich, and the new industrial revolution requires new norms. In the Swiss valley, where today’s workshops are located, Antoine LeCoultre founded a watchmaking factory in 1833 to prepare for the challenges of the future. He brought together the various processes that were originally engaged in production at home, became a pioneer in mass production, and established a quality control system. The Great Workshop has achieved rapid development, and at the same time has formed a bold and innovative entrepreneurial spirit.

 Today, following the traditional craftsmanship is still the cornerstone of the watch factory. It is for this reason that the movement of the MASTER TOURBILLON DUALTIME Tourbillon Masterpiece series has a special status in writing another new chapter in the history of modern timepieces. In 2009, the 978 movement won the Concours international de Chronométrie. Its performance is unmatched, and the letter B is added to the movement’s name because it has a tiny but exciting innovation.

 The tourbillon of the new MASTER TOURBILLON DUALTIME Tourbillon Master Time Series watch has an unforgettable distinguished style. A translucent, lightweight design with a new titanium tourbillon frame, the structure is sturdy and smart. The deep transparent effect is impressive, and other features of the Master Tourbillon Dualtime watch are also appreciated for their refinement and practicality. The center of the silver-plated dial is decorated with the sun’s radial pattern. The hours and minutes are displayed by the crown prince-like hands. The 3 o’clock and 9 o’clock hour markers are specially shaped. The applied hour markers have been polished 4N. The 11 hour markers are fluorescent. For processing, the tourbillon with small seconds rotates one revolution per minute to correct errors caused by position changes. In addition, due to Jaeger-LeCoultre’s special requirements for accuracy, the tourbillon trimmer located below the rotating frame makes the accuracy of the tourbillon even greater.

 Due to the frequent travel of modern people, the MASTER TOURBILLON DUALTIME tourbillon dual time zone master series watches provide two practical additional functions-second time zone time and date display. The destination time is indicated by a centrally located hand, which can be easily adjusted via the winding crown. Because of this layout, when the wearer wants to go to any region in the world in time to make an appointment, his time can be clearly displayed in a hierarchical form. As a reference, the residence time is displayed on the dial in the form of a 24-hour clock. Logically, the date display adheres to the fine tradition of the Master Control series. It is displayed synchronously with the destination time through the central hand. It can be adjusted in both directions. The top of the hand is decorated with a red triangle with a curved edge to form a visual relationship with the current date. Distinction. Thanks to Jaeger-LeCoultre’s specially developed and patented mechanical structure, the date hand can make a large jump between the 15th and 16th on both sides of the tourbillon.

 The beautiful and exquisite appearance echoes the creative mechanical structure perfectly. The thickness of the rose gold case has been reduced by almost half a millimeter to fit all wrists. Although the diameter of 41.5 mm is still used to perfectly match the size of the tourbillon, the lugs and bezels have a more slender design. The MaSTER TOURBILLON DUALTIME Tourbillon Master Time Series watch is equipped with a crocodile leather strap with a gold pin buckle. It is equipped with a Jaeger-LeCoultre movement that breaks the world record in terms of accuracy, and through the sapphire crystal back The fine watchmaking craftsmanship and traditional details of a precious movement can be seen at a glance.
