Jaeger-LeCoultre 834

Caliber 834 is a manual-winding movement manufactured entirely in-house by Jaeger-LeCoultre. Developed exclusively for the Reverso Tribute Geographic, it features an integrated world time complication with a static city display and rotating 24-hour ring, adjusted via a hidden pusher between the top lugs. The Grande Date complication uses two side-by-side discs to display the date in a compact format suited to the rectangular case. The movement is reserved for the Reverso Tribute Geographic.
