About this reference

This model features a case design that reinterprets the 62GS, which debuted in 1967 as Grand Seiko’s first automatic mechanical watch, with a modern sensibility. The dial expresses the harsh yet beautiful scenery of Shinshu, the birthplace of the Spring Drive watches, covered in deep snow around the seasonal period known in Japan as Taisetsu . It is powered by the Spring Drive Caliber 9R65, an automatic movement equipped with a power reserve indicator and offering a power reserve of approximately 72 hours when fully wound.
