Description
In autumn, when the moon’s light fills the sky with its soft glow, drops of dew gleam in the light in a moment that captures the beauty of the season. From Grand Seiko, the SBGM257 “Moondrop” expresses such a special moment with its textured blue dial. Thanks to its modern geometric spiral pattern, the dial changes in appearance based on the angle of the light, recalling how dew drops gleam in the moonlight. The intricate pattern imparts a refined sense of structure, a fitting complement to the Zaratsu-polished case and the high precision of the Caliber 9S66 GMT movement. Prized for its accuracy, beauty, and reliability, this movement enables the wearer to track two time zones simultaneously. The gold-colored GMT hand can be set to one’s home time or any time zone of one’s choosing. The local hour can be changed in one-hour increments when the crown is extended to the first click position, making time zone adjustments simple and intuitive. The power reserve is approximately three days.
