40mm Stainless Steel Case with Black Sapphire Dial Inspired by the Katana | SBGA489

The Japanese sword, known as the katana, is a world-renowned masterpiece in steel. Crafted through a distinctive and sophisticated process. The katana is made from earth, fire, water, and air and is derived from nature and brought together through expert craftsmanship. Grand Seiko honors the katana and kawagane with the U.S.-exclusive SBGA489. The hardness and beauty of the blade edge (kawagane) inspire the black dial, whose dial pattern evokes the unique texture in the variations of tamahagane, the “jewel” steel from which traditional katana swords are fashioned. The Caliber 9R65 uses sophisticated modern technology coupled with the skilled hand of a master craftsman for the finest adjustments and highest precision possible, highlighting the seamless passage of time with a Spring Drive movement.
