[The thinnest version on the Internet] Mx new product - Vacheron Constantin Patrimony Contemporaine Heritage Series Ultra-thin Perpetual Calendar Watch[Case]: The watch has a diameter of 41mm and a thickness of 9.4mm, which is only 0.03cm different from the thickness of the authentic product, making it the thinnest version on the Internet. The watch has simple lines and smooth contours, adhering to the consistent slimness and elegance of the Heritage Series. It is a "milestone"-style excellent achievement in the pursuit of the ultimate slim timepiece craftsmanship.[Dial]: The watch follows the consistent pure and simple style of this series, with delicate trapezoidal hour scales, stick-shaped hands, slightly arched arc dial design and "bead-type" minute scale circle. On the milky white silver-plated dial, in the crescent-shaped moon phase profit and loss display plate, a golden bright moon flows in the deep blue night sky, slowly. (The month function at 12 o'clock is the only one in the market that is consistent with the genuine product with 48 small grids, not other wrong versions in the market.)[Movement]: Based on CITIZEN9015, the self-developed 1120 QP automatic winding integrated movement has raised the slimness of the watch to a new level. The hollow rotor makes the watch movement more ornamental, especially the Vacheron Constantin "Maltese Cross" logo pattern in the center of the rotor, which adds a unique connotation and charm to the watch.
