Jaeger-LeCoultre Duomètre à Sphérotourbillon

About this reference

The Jaeger-LeCoultre Duomètre à Sphérotourbillon reference Q1646420 was introduced in 2012 as a limited edition of 75 pieces. This platinum model features the manual-wind Calibre 382, which utilizes the Dual-Wing architecture to separate the timekeeping gear train from the complication power supply. Collectors value this reference for its multi-axis tourbillon that rotates every 30 seconds at a 20-degree tilt and its flyback seconds function, which allows for precise synchronization to a reference clock via a pusher at 2 o'clock. The 42mm case houses a silvered grained dial with a 24-hour GMT subdial and dual power reserve indicators. On the secondary market, this reference typically trades in the $130,000 to $170,000 range depending on condition and provenance. A notable production detail is that the movement plates and bridges are crafted from untreated German silver, a hallmark of the high-end Duomètre series.
