The SBGA491 Grand Seiko watch pays homage to the iconic Japanese katana sword, a symbol of masterful steelwork deeply entrenched in Japan's cultural legacy. Its dial pattern mirrors the unique texture of tamahagane, the revered "jewel" steel used in crafting these swords. The vibrant green dial draws inspiration from shingane, a particularly robust variant of tamahagane.
Encased in a 40mm diameter of stainless steel, the design reinterprets Grand Seiko's classic 44GS form to align with contemporary trends. The case boasts a striking, faceted design with flawlessly flat and mirror-polished surfaces, a testament to Grand Seiko's renowned Zaratsu finishing technique.
At its heart lies the Spring Drive caliber 9R65, seamlessly blending the potent torque of a mechanical watch with a high-precision regulator. Remarkably, it achieves an accuracy of one second per day. The second hand gracefully glides in a continuous, smooth motion—a distinctive trait of Spring Drive technology.
The SBGA491 exemplifies the fusion of heritage and innovation that defines Grand Seiko. Its meticulous craftsmanship and technological prowess pay tribute to the time-honored artistry of Japanese sword-making, resulting in a timepiece of exceptional precision and beauty.
