Heritage CollectionSTGK009
The refined elegance of Grand Seiko
STGK009 catches the eye with its mother-of-pearl dial and with a blue seconds hand that is tempered by hand to a deep and powerful blue. With lines that are classic but details that are distinctively Grand Seiko, it is at once subtle and yet striking. It is powered by a remarkable automatic movement created especially for Grand Seiko’s women's watches which combines durability, accuracy and a remarkable 50 hours of power reserve with a slimness that belies the movement’s strength. The elegance shines, both inside and out.
