Most of the world’s leading watch brands have, one time or another, outsourced movements from Jaeger-LeCoultre, which has earned the company the illustrious status of “the watchmaker’s watchmaker.” Renowned for its impressive watch complications and mechanical mastery, Jaeger-LeCoultre also makes exquisite timepieces to house its movements. One such example is this limited edition Jaeger-LeCoultre Master Grand Reveil that marries precious platinum, dazzling diamonds, and a high-complication mechanical movement.

The Innovation of the Jaeger-LeCoultre Master Grand Reveil

In 2005, Jaeger-LeCoultre debuted the Master Grand Reveil watch as an evolution of its 1989 Grand Reveil and its 2001 Master Grande Memovox. Packed with features, this high-complication Jaeger-LeCoultre not only includes a complete perpetual calendar but also a mechanical alarm. 

The perpetual calendar portion of the watch displays the day, date, month, year, and Northern Hemisphere and Southern Hemisphere moon phases across four subdials. There’s also a 24-hour display to indicate A.M. / P.M. hours and the “danger zone” is marked in red to warn the wearer from setting the calendar functions during this time to prevent damage to the movement. Of course, this being a perpetual calendar, as long as the watch keeps running, the movement will automatically adjust itself to display the correct time and date regardless of how many days in a month or whether it is a leap year or not. 

The Master Grand Reveil Pairs a Perpetual Calendar and Mechanical Alarm

The other significant feature of the automatic Jaeger-LeCoultre Master Grand Reveil is its alarm functionality. Rather than just offering an audible alarm, the Master Grand Reveil boasts a dual-function alarm where the user can choose between a loud bell sounded out by a hammer hitting a bronze gong or a subtle vibration alert. A small aperture located at 11:30 on the dial lets the wearer know which alarm mode the Master Grand Reveil is in while the red-tipped hand shows what time the alarm will go off. The option of a tone or a pulsation signal is a first for a mechanical alarm watches and exemplifies Jaeger-LeCoultre’s focus on innovation.

The remarkable functionality of the watch is thanks to the automatic Jaeger-LeCoultre Caliber 909 movement, made especially for the Master Grand Reveil model. Operating at a frequency of 28,800 beats per hour, Cal. 909 supplies the watch with 45 hours of power reserve.

Design of the Limited Edition Platinum and Diamond Master Grand Reveil 

While Jaeger-LeCoultre offered the Master Grand Reveil in several metal options including stainless steel and rose gold, the most opulent version of them all is this platinum and diamond edition; the limited edition ref. 149.6.95/Q163643A.

The Jaeger-LeCoultre Master Grand Reveil ref. 149.6.95/Q163643A sports a 43mm platinum case embellished with a diamond-set bezel and diamond-set lugs. There are also a dozen diamonds on the black dial adjacent to the hour markers. Matching the black dial is the elegant black leather strap, fitted with a platinum double deployant clasp. 

The platinum caseback of this Jaeger-LeCoultre Master Grand Reveil is marked with the “Master Control 1000 Hours” hallmark. Jaeger-LeCoultre’s Master Control program subjects a finished watch to a series of tests over 1,000 hours to ensure impeccable performance. What’s more, since the Master Grand Reveil ref. 149.6.95/Q163643A is limited to only 100 pieces, the caseback is engraved with its unique production number, 1/100.

An exceptional expression of Jaeger-LeCoultre’s technical prowess and sophisticated design language, the platinum and diamond Master Grand Reveil is the ultimate marriage of art and engineering.
