Released in 2007, the Jaeger LeCoultre Duomètre’s inspiration came from birds and how nature inspires us to seek the perfect balance. A chronograph with a unique innovation named the “Dual Wing”, the concept was to have two separate sources of power. One source of energy is used for timekeeping, while the second is used for the complications. To realize this concept, JLC gave the Duomètre’s movement two mainsprings with their own gear trains that would then converge into one shared regulating organ. With dedicated sources of power for its timekeeping and complications, the accuracy of the Duomètre is not degraded with the addition of complications as the torque generated is consistent, thus allowing JLC to evolve the Duomètre from the chronograph that they initially released to one of their most complicated offerings, such as the Duometre Quantieme Lunaire ref. Q6042422 that we have here. Made of 18kt rose gold and featuring a 42mm diameter, the ref. Q6042422 boasts an impressive partially skeletonized silver dial that reveals its litany of complicated indicators and the mechanics within its manual-wind cal. 381 movement. Featuring the time in hours, minutes, and seconds, the date, a moon phase indicator and a foudroyante capable of displaying 1/6th of a second, we can clearly understand that JLC has devised the Duomètre with the sole purpose of housing complications and providing them with a vehicle for flexing their impressive watchmaking might. As beautiful a watch as it is complicated, the Duomètre shows exactly why JLC is the watchmaker’s watchmaker.

Showcasing your talents as a watchmaker is much harder in today's day and age, given how complicated some timepieces are getting. However, the ref. Q6042422 manages to still wow JLC's collectors with its attention to detail and complication-packed cal. 381 movement.
