Jaeger-LeCoultre Duometre Heliotourbillon Perpetual Watch Review

For nearly two centuries, Jaeger-LeCoultre has continuously developed sophisticated and complex mechanical structures to optimize the movement regularity. The most representative of these is Jaeger-LeCoultre's development of professional tourbillon technology and the Duometre double-wing system launched in 2007. The latter is one of the brand's most eye-catching patents. Watchcloneprice - who makes the best Jaeger LeCoultre clone watches at cheap price, replica watches sale online.

The Duometre bi-wing system is equipped with dual barrels and two independent sets of gear trains, loaded in the same movement and connected to the same regulating mechanism. One gear train powers the time display, while another drives all additional functions. This method separates the power supply source to ensure that the timing accuracy of the watch is not interfered with by the operation of complex functions, further ensuring the accuracy of Jaeger-LeCoultre's highly complex functions.

In 2024, Jaeger-LeCoultre will launch the Duometre Heliotourbillon Perpetual in a breakthrough. This watch has several major features. First, with the support of the Duometre bi-wing system, it launches an innovative three-axis tourbillon for the first time, presenting a "gyro"-like visual effect.

Under the operating mechanism of the three-axis tourbillon, Jaeger-LeCoultre created a 20-second display window in the space on the left side of the dial of this watch. Each rotating axis is equipped with a tiny red arrow, and their timing changes every 20 seconds. When all three sets of red arrows run for 20 seconds, it means that the three-axis tourbillon rotates for one minute.

Secondly, this watch is equipped with the new 388 movement developed by Jaeger-LeCoultre watchmakers to support the operation of a perpetual calendar function with a large date display. According to Jaeger-LeCoultre, a major feature of the 388 movement is that the hours and minutes can be adjusted forward or backward without affecting the perpetual calendar. The vibration frequency of the 388 movement is 4 Hz (28,800 times per hour), which further improves timing accuracy.
