Jaeger-LeCoultre Duomètre à Quantième Lunaire 18K Rose Gold (Ref. Q6042422) – Full Set

Up for auction is a pinnacle of haute horlogerie from the "Watchmaker of Watchmakers": The Jaeger-LeCoultre Duomètre à Quantième Lunaire (Reference Q6042422) in solid 18K rose gold. This 42mm masterpiece features JLC's revolutionary "Dual-Wing" movement architecture, which solves a fundamental law of physics by separating the power supply of the timekeeping mechanism from the complications. Featuring a breathtaking jumping foudroyante seconds hand and an ultra-precise moon phase, this is a grail-tier timepiece for discerning collectors.

Key Features

* Revolutionary Dual-Wing Concept: Houses two independent power barrels and gear trains within a single movement—one dedicated entirely to precision timekeeping and the other to the complications.
* Seconde Foudroyante (Jumping Seconds): A mesmerizing lightning-fast seconds hand at 6 o'clock that completes a full rotation every single second, tracking intervals down to 1/6th of a second.
* High-Precision Moon Phase: An exceptionally accurate calendar moon phase display displaying the age and phase of the moon for both the Northern and Southern hemispheres.
* Dual Power-Reserve Indicators: Features two distinct power indicators on the lower half of the dial, showing the independent power reserves for both gear trains.
* Crystalline Matte Dial: A striking silvered grained (grained crystalline) dial that offers perfect contrast against the elegant rose gold case and blued steel hands.
* Calibre 381 Masterpiece: A manually wound movement crafted from untreated German silver, hand-beveled, and decorated with sunray Côtes de Genève, visible through the sapphire caseback.
