Speedy Heartbeat Tourbillon - Mysterious Excellence. This Cartier Drive de Cartier tourbillon watch is equipped with the 9452MC floating tourbillon movement and proudly bears the Poin?on de Geneve hallmark of quality. The elegantly operating tourbillon exudes an air of mystery, while the dial is adorned with white electroplated twisted engraving. Black transfer Roman numeral hour markers stand out prominently against the frosted silver-hued openwork grid. In the early morning, sunlight streams in, casting dappled reflections through the black-and-white openwork grid and screen onto the finely textured surface resembling frosted white. Through the sapphire crystal, one can faintly observe a sunburst effect, as if it is conveying a sense of mystery to you. The sword-shaped blue steel hands are centrally positioned above the small seconds subdial, adding a touch of charm to the silver-gray dial. Dimensions: 41.5mm x 13.8mm.
