JAEGER-LECOULTRE DUOMETRE CHRONOGRAPH MOON REF. Q622252J

The sectorized dial of the Duometre Chronograph Moon is extremely legible in terms of both design and function: moon phase on the chronograph counter, whose monopusher triggers start/stop/reset, day/night indicator on the left-hand hour counter, power reserves on either side of the seconde foudroyante at 6 o’clock. At the heart of this complication watch beats the Calibre 391, distinguished by its independent twin barrels and gear trains: one dedicated to the hour/minute indication, the other to complications. Offering different levels of finishing, Calibre 391 is a watchmaking spectacle to be admired under the sapphire crystal on the back of the timepiece.
