The Grande Maison in the Vallée de Joux unveils the Master Tourbillon Dualtime equipped with a new tourbillon carriage. Within this superb timepiece with its classic lines and pure design, the ingenious tourbillon mechanism recaptures its initial function: that of a device designed to further improve rating precision.

The Master Tourbillon Dualtime housing an automatic movement, Jaeger-LeCoultre Calibre 978B, displays a second time-zone on a dial testifying to a degree of aesthetic perfection that is inseparable from technical genius. On this model equipped with a reworked tourbillon carriage, the watchmakers of the Manufacture have made no compromises regarding its performance, reliability and sturdiness. The titanium tourbillon regulator accompanies a high-precision automatic precision.

As a benchmark in the realm of Fine Watchmaking, the Manufacture Jaeger-LeCoultre leaves no detail to chance. Patented by the Manufacture Jaeger-LeCoultre, the date indication is adjustable in both directions and makes a bigger jump between the 15th and the 16th so as not to obstruct the view of the titanium tourbillon carriage.

An exceptional timepiece intended for daily wear, the Master Tourbillon Dualtime proves its sterling qualities of precision, reliability and water resistance within the stringent framework of the 1000 Hours Control. This set of rigorous trials that has become a watch industry legend now includes rating regularity and amplitude measurements relating to the tourbillon regulator, including under conditions involving small impacts.

When ingenuity spells elegance: the jumping date display
Since travel is a frequent part of contemporary living, the Master Tourbillon Dualtime features two closely linked additional indications: a second time-zone display and the date. Travel time is indicated by central hands and easily adjustable via the crown. This arrangement serves to maintain a clear hierarchy of the indications when it comes to arriving at an appointment at the exact time and date, wherever one may happen to be. As far as the reference time is concerned, that of the customary place of residence, it appears on a 24-hour graduated scale placed in the upper part of the dial.

Mechanical inventiveness is matched by aesthetic refinement: the pink gold case is a half-millimetre smaller to suit all wrists. An alligator leather strap with a gold pin buckle set the finishing touch to the Master Tourbillon Dualtime fitted with a sapphire crystal caseback revealing the secrets and traditional Fine Watchmaking finishing of a prestigious Jaeger-LeCoultre that holds the world record for precision timing.
