Patek Philippe Starry Sky 5102 Day and Moon Geneva Sky Series. Can you imagine wearing the starry sky on your wrist? This starry sky watch features a unique celestial function. You can enjoy the Geneva sky map on the blue round dial, along with the golden trajectory of the moon. It took 20 months to create and is modified from the imported 9015 movement, with the same core as the genuine product. The moon on the dial will automatically change according to the phases of the moon in the sky, from full moon to crescent. The front and back glasses of the case are treated with advanced technology to enhance light refraction, making the dial look more transparent, as if there were no glass at all. The 5 o’clock position crown can adjust the starry sky dial. The case body of our factory is engraved with Patek Philippe patterns using CNC deep engraving, with a strong sense of three-dimensionality and concavity. The starry sky has been upgraded to rotate 24 hours. The watch size is 43mm!!!
