【Product Name】 CASIO STANDARD MENS CASIO MTP-M305D-9A 【Product Features】 ・ The Casio MTP-M305 series is the perfect wristwatch for those who want to add a touch of elegance to their everyday life. A notable feature is the moon phase indicator at the 6 o'clock position, which romantically displays the phases of the moon. This mechanism is built with a unique technology that rotates a disc with two moons drawn on it (top and bottom) over a 59-day cycle, showing the moon's phase by revealing the top half of the disc. Based on the moon's orbital period of approximately 29.53 days, this mechanism is a testament to the ingenuity of watchmakers and minimizes errors. The moon phase indicator, once used by sailors to understand the tides, is now a beautiful decoration adorning the face of a watch. The rectangular, stylish case has a modern design reminiscent of a smartwatch, giving a sophisticated impression.
