Duomètre A Quantième Lunaire

The Jaeger-LeCoultre Duomètre à Quantième Lunaire, reference Q6042521, is one of the most conceptually fascinating watches in fine watchmaking, built around Jaeger-LeCoultre's revolutionary Dual-Wing concept, two entirely independent mechanisms sharing a single case, one dedicated solely to precision timekeeping and the other to powering the calendar and moonphase displays. This certified pre-owned example is offered in excellent condition and presented as watch only.

Crafted in 18k pink gold, the Q6042521 presents the Duomètre in a substantial 42mm round case measuring 13.5mm in height, with a sapphire crystal caseback revealing the extraordinary mechanical architecture within. Warm, classical, and entirely unlike anything else on the wrist, both in appearance and in mechanical philosophy.

The silver dial is elegant and beautifully organised, with mixed indexes and Dauphine hands across a layout that includes a foudroyante seconds display sweeping in discrete jumps at six beats per second, a date indication, and a moonphase display. A dial that hints at the extraordinary complexity within without ever feeling crowded.

Powering the watch is the Jaeger-LeCoultre Calibre 381, the manufacture's celebrated Dual-Wing movement with two separate power reserves working in perfect synchronisation, an engineering solution that allows the foudroyante seconds to operate with a precision that conventional single-barrel movements cannot achieve. A genuinely groundbreaking piece of mechanical thinking, executed with complete mastery.

Available now at Minty Watches, this certified pre-owned luxury watch is an exceptional opportunity for collectors of pre-owned luxury timepieces in Geneva seeking one of the most intellectually compelling complications in modern watchmaking.

A pre-owned watch in Geneva where two hearts beat as one, perfectly in time.
