Calibre JLC 182
Calibre 182 has 13 patents pending. It is a hand-winding movement made up of 1,406 pieces. It runs at 28,800 vph and has 99 jewels. With double barrels, it has a power reserve of 50 hours. It is related to the “Dual Wing” JLC 380 movement.
The repeater function is notable in that it includes all four notes needed for the full Westminster melody. On the hour, it plays all five bars of the melody, with full quarters ringing hours, and even optional minute repetition. It can also be set to Petite Sonerie, playing only a portion of the melody and chiming the hours. This movement includes the welded gongs from previous Jaeger-LeCoultre movements and introduces a new two-part “trebuchet” hammer design, later used in other Jaeger-LeCoultre repeaters.
Calibre 182 was only ever used in the limited-production Duomètre à Grande Sonnerie.
