In addition to the significant improvements in precision timing accuracy and functionality, as well as some unique innovations, the biplane system has also allowed us to revisit traditional precision technology with an impressive new and unique appearance while incorporating a classic watch style of. In recent years there has been a dramatic increase in the number of tabulation topics from the introduction of new adjustment and escapement devices to the acquisition of high frequencies and the achievement of the integration of multiple tourbillons. However, a distinctive and promising attempt is the biplane concept. This revolutionary idea, born in Jaeger-LeCoultre in 2007, presents a completely original dual-mechanical structure. It is so unique that Järme Lambertre, Jaeger-LeCoultrie's CEO, says: "It's not a simple evolution but a real revolution, adding a new chapter in the history of watchmaking." In addition to the significant improvements in precision timing accuracy and functionality, as well as some unique innovations, the biplane system has also allowed us to revisit traditional precision technology with an impressive new and unique appearance while incorporating a classic watch style of. So, what is the idea behind this biplane, which has opened up new technologies and designed the avenue in the Duomètre series of wings? A watch, two brains For example, the wing system can be simply summarized as: a watch, two brains. In other words, two different devices coexist within the same movement. They share the same tuning body, but each device has its own source of energy. The biggest advantage of this new dual-core architecture is that the energy lost using some complex functions does not affect the supply of power to the calibration mechanism that controls the accuracy. This revolutionary nature of coexistence allows the wristwatch to adopt the corresponding device for different purposes. The new design was first applied to the 2007 Duomètreà Chronographe biplane chronograph. In this special sense of the watch, the chronograph function and timing function to share a calibration body. However, each of these two functions has its own independent source of energy and a specific wheel organization. Therefore, whether to open or stop the chronograph, will not affect the measurement of time, as well as minute and minute precision timing. The same independent dual energy source system also enables the chronograph function to measure jump seconds to one-sixth of a second. The second application of the concept of biplane and the first very different, is a 2009 Duomètreà Quantième Lunaire moon phase calendar calendar. In this watch, one of two independent energy sources powers the tuner directly, while the other is used to show the moon phase gains and losses in hours, minutes, seconds and two hemispheres. Their synchronization is achieved by jumping one-sixth of a second every second. In short, we can say that this is the only watch in the world that can be accurate to one-sixth of a second without stopping the adjustment mechanism.
