Jaeger-LeCoultre Master Grand Tradition Grand Complication

August 17, 2014

This eye-catching new grand comp from Jaeger-LeCoultre incorporates three complications: a minute repeater, a flying tourbillon and a zodiacal calendar. The Master Grande Tradition Grande Complication will be produced in an 8-piece white gold limited edition, honoring the exclusivity of the movement (JLC Cal. 945 which first debuted in 2010) and the intricate gem-set case (19.8 carats / 294 total diamonds). It will premiere at (increasingly popular) Watches & Wonders in Hong Kong from September 30th to October 2nd, 2014.

The watch dial depicts a sky-chart of the northern hemisphere. A sun performs a full revolution in 24 hours around the edge of the dial, thereby displaying a 24-hour indication, zodiac signs (depicting the position of the constellations at any given time of the year), as well as the days and months appearing on a circular scale surrounding the dial.

Contrary to the traditional construction based on both lower and upper bridges, a flying tourbillon is held only on the movement side and thus features a single cantilevered pivot. The entire mechanism consists of 73 parts and measures 12.42 millimetres in diameter and 3.85 in height. It is constructed from titanium and fitted on a lubricant-free ceramic ball bearing system. The silicon parts of the escapement, such as the lever with its integrated pallets and the escape wheel, are clearly visible.

Additionally, the watch incorporates a minute repeater equipped with ‘trébuchet hammers, in which the sound is generated by two crystal gongs directly fixed to the sapphire crystal. It is operated by a slide on the lower left side of the case. The system is based upon Jaeger-LeCoultre’s new cathedral gong which debuted in 2010, procuring an exceptionally rich sound. These gongs are made of a special alloy and manufactured completely in one piece. Their cross section is square rather than the usual round shape, in order to provide a larger contact point for the hammer that can in turn strike more forcefully.

The crown is meticulously set with baguette-cut diamonds, while two rows of baguette-cut diamonds extend to the right and left of the crown to adorn the convex-shaped side of the case, and descend to the lugs.
