Grand Seiko Elegance Collection “Snowdrop” Automatic GMT – 39.5 mm

Reference Number
SBGM255G

As winter’s cold gives way to the warmth of spring, melting snow forms droplets that glisten under bright sunshine. The SBGM255 “Snowdrop” captures the beauty of this richly symbolic seasonal moment. Thanks to its modern geometric spiral pattern, the dial changes in appearance based on the angle of the light, just as melting snow refracts rays of spring sunshine. 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 tempered blue 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.
