Calibre 834 is a manual-winding movement crafted by Jaeger-LeCoultre specifically for the Reverso Tribute Geographic. This fully in-house integrated movement is optimized for the rectangular Reverso case. It incorporates a world time complication with a fixed city display and a rotating 24-hour ring controlled by a hidden pusher. It also utilizes a patented Grande Date mechanism with side-by-side discs for units and tens to ensure a compact layout.
