Jaeger-LeCoultre - Innovative Master Control Timepiece

Jaeger-LeCoultre, one of the most prestigious watch manufactures in the world, has marked the year 2006 by introduction of a unique creation - the first classically styled watch from Master Control line equipped with a tourbillon regulator.

The novelty Master Control timepiece is characterized by classic lines and ultimate precision provided by the tourbillon. The Jaeger-LeCoultre watchmakers, having accumulated excellent skills in watch designing and engineering, have conceived and given birth to one more innovative mechanism the complexity of which represented a real horological challenge.

The tourbillon regulator produced from titanium takes care of a self-winding movement -Caliber Jaeger-LeCoultre 978. The movement is manually crafted and decorated performing at 28,800 vibrations per hour and providing ultimate precision.

Aesthetically appealing dial of the new Master Tourbillon catches attention due to the tourbillon in work visible trough the circular aperture. The timepiece provides an additional advantageous feature — the display of a second timezone. The clear design of the Master Tourbillon allows a busy traveler to compare reference time with local time after just a single glance dropped at the dial. The upper part of the dial features a 24-hour subdial adorned with a nice motif defining the watch owner's reference or home time. The hour and minute hands indicating local or travel time are right in the center of the main dial. It is possible to reset the time in either direction - forwards or backwards.

However, the creative genius of the manufacture's watchmakers has not stopped at the mentioned accomplishments - the watch offers the new way of date indicating. The date is featured with the help of a patented device that is possible to be adjusted in both directions. There is the date scale at the edge of the dial -from 1 to 31 - the central arrow-like hand jumps from the 15th to the 16th day of every month not to break the view of the tourbillon turning cage.

The Master Tourbillon with 41.5 mm in diameter case offers the choice between traditional rose gold models, platinum (edition limited to 300 pieces) as well as steel ones. It is presented with matt alligator leather strap with a comfortable folding buckle in steel ,18K white gold or 18K pink gold or.

The precise and functional Jaeger-LeCoultre Master Tourbillon reaches top level of refinement and represents the most suitable timepiece for everyday wearing.

The Tourbillon Wonder

Jaeger-LeCoultre master watchmakers developed the tourbillon aiming to further increase the operational accuracy of the timepiece. The tourbillion is responsible for compensating for rate errors in upright positions. The complicated mechanism developed by Jaeger-LeCoultre corresponds to the highest standards of reliability, precision, and durability.

To understand better the innovative idea realized by Jaeger-LeCoultre, first it is necessary to remember the main principles the tourbillon work is based upon. The rotational movement of the tourbillon requires energy the amount of which depends upon the size of the tourbillon cage - the bigger is the cage, the more energy the tourbillon needs. As a common solution of economizing the energy, watchmakers make the size of the tourbillon cage and the balance smaller and reduce the movement frequency. However, this is not the best decision in regard of the accuracy of the mechanism. So, Jaeger-LeCoultre watchmakers took the challenge of coming up with another solution of providing the tourbillon with enough energy.

They decided to create an absolutely new balance of a rather generous size - the balance is meant to supply enough energy to the self-winding movement to maintain the cage's motion and work at the 28,800 vibrations per hour, thus offering high-precision of the mechanism. The newly elaborated balance appeared as the result of thorough research fulfilled in the manufacture's labs.

It is worth mentioning that the movement of the Jaeger-LeCoultre Master Tourbillon rewinds in just one direction. During the research it was concluded that a watch worn on the wrist rewinds two times faster when it rewinds in single direction if compared to a movement rewinding in dual-direction.

The technical perfection of the Master Tourbillon is further underlined by immaculate decoration of its movement. The tourbillon cage weighs just 0.28 g. the lightness of the titanium alloy it is produced from adds to the watch's precision.

Jaeger- LeCoultre watchmakers subjected every Master Tourbillon timepiece to rigorous 1000-hour testing. This is naturally a reliable way to guarantee the timekeeper's outstanding performance. The special tests were applied to the innovative tourbillon regulator to check it reliability and amplitude. The watchmakers made sure that the mechanism's perfect work was not any way affected when the watch was subjected to minor impacts and shocks. The watch provides 48-hour power reserve.
