Cartier Central Chronograph Watch

Cal.9907 MC hand-wound movement, power reserve about 50 hours, 18K rose gold case, 18K gold bead-shaped crown, decorated with a convex round sapphire, sapphire crystal and case back , The case is engraved with an independent number, the double-layer dial, the chronograph functions are displayed in the center of the dial, the black alligator leather strap, the 18K rose gold adjustable folding clasp, the water-resistant depth is 30 meters, the case diameter is 42 mm
Recommended reason:
     When the chronograph starts, the chronograph second hand located in the center of the dial starts to run, and the large curved inner dial in the center is a 30-minute chronograph. In this way, the timekeeping structure of the watch and the central chronograph structure composed of the hour and minute hands are completely ‘isolated’. To make it clearer, the hands that show the time never block the chronograph hands.
