Description
The Japanese sword, known as the katana, is a world-renowned masterpiece in steel. Crafted through a distinctive and sophisticated process, the katana has created fascination and allure the world over. Derived from nature and brought together through expert craftsmanship, the katana is made from earth, fire, water, and air. Iron sand is drawn from the earth and then heated in a furnace known as a tatara. The melted sand forms the Japanese steel, known as tamagahane. From this Japanese steel, two variations can be found. The first is the high-carbon steel used for the outer sharp edge, or kawagane, and the second is the strong inner core of the blade, or shingane. Grand Seiko honors the katana and kawagane with the U.S.-exclusive SBGA491.

Polishing the katana requires handcraft of tremendous skill and dexterity, and the same can be said of crafting Grand Seiko watches using the Zaratsu polishing method, particularly the 44GS case design, which established the Grand Seiko style in 1967.

The resilience and strength of shingane inspire the green dial of SBGA491, whose dial pattern evokes the unique texture in the variations of tamahagane, the “jewel” steel from which traditional katana swords are fashioned.

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.
