Jaeger-LeCoultre’s Duomètre à Quantième Lunaire Limited – Wednesday Watch

Jaeger-LeCoultre just introduced another Duomètre model, the Duomètre à Quantième Lunaire Limited in white gold. The new timepiece is restricted to just 200 pieces worldwide.

I once heard that the entire Jaeger-LeCoultre crew had to learn how to pronounce the word “Duomètre” in an authentic French accent before the big introduction of the Duomètre models started. During an event where the Duomètre was introduced, the first man to ask about this timepiece walked towards the Jaeger-LeCoultre representative and managed to pronounce it as American-English as possible. Now, as the brand’s representative you can do two things: try to correct the potential customer and teach him how to pronounce it in authentic French with the risk of angering him, or keep their mouth shut and just use the same pronunciation as the potential customer did and try to sell the timepiece.

The Jaeger-LeCoultre representative played it safe here.

Besides being a stunning looking timepiece of superb quality and finish, the main attraction for its owner is in the highly complex movement; one that is in place to solve a problem that you probably weren’t even aware of, namely the negative influence of a complication (such as a moon phase) on the accuracy of the movement, and thus time.

Engineers over at Jaeger-LeCoultre came up with a system called “Dual-Wing,” that was introduced in 2007 with the Duomètre à Chronographe. With this system, Jaeger-LeCoultre uses two independent power supplies in the watch. One power supply is dedicated to the complication of the movement, and the other one is used to keep the basic functionality up and running. Both supplies are synchronized through the jumping seconds hand mechanism driven by the escapement.

In the end, the Quantième Lunaire Limited shows time, date, and the age of the moon, made possible by Jaeger-LeCoultre’s caliber 381 movement with its 369 components. An impressive piece of art made possible by using the 178-year experience of the company from Le Sentier, Switzerland.
