A black dial inspired by the Hotaka Mountains
This design captures the dynamic cliffs of the Hotaka Mountains, which stretch across Shinshu, where Spring Drive watches are crafted. Formed by ancient volcanic activity that violently uplifted the land, the Hotaka Mountains have been shaped over time by wind and snow into a dramatic alpine landscape. The dial pattern reflects these majestic ridgelines, rendered in a lustrous black that evokes the harshness and dynamism of nature.
A GMT Design That Combines Functionality and Beauty
Rooted in the Grand Seiko Style, the grammar of design that imbues Grand Seiko watches with an unmistakable presence, the case has evolved to have a sporty yet refined character. It offers 20 bar water resistance, ensuring reliability even in tough environments. The two-way rotating bezel is fitted with an insert made of sapphire glass, known for its high scratch resistance and lustrous transparency. The layout, with white Lumibrite applied across the daytime hours, enhances intuitive readability and adds a distinctive visual identity.
Caliber 9R66
With a power reserve of 72 hours and accuracy of ±15 seconds per month, this was the first Spring Drive movement to incorporate a GMT mechanism.
