The Japanese sword, known as the katana, is a world-renowned masterpiece in steel. Deeply rooted in Japan’s history and cultural heritage, the famous curved blade is the product of centuries of learned craft.
The dial pattern of SBGA489 evokes the unique texture in the variations of tamahagane, the “jewel” steel from which the swords are made. The carbon-rich beauty of kawagane, one such variation, is the inspiration for the black dial.
Measuring 40mm in diameter, the stainless steel case features Grand Seiko’s iconic 44GS form, re-imagined to accommodate modern trends. It features a beautiful, faceted design with perfectly flat and mirror polished surfaces, all made possible via Grand Seiko’s acclaimed Zaratsu finishing method.
SBGA489 is powered by Spring Drive caliber 9R65, which combines the high torque of a mechanical watch with a high-precision regulator. It features an accuracy rating of one second a day. The second hand glides in a smooth motion, a defining featuring of Spring Drive.
SBGA489 is a US Exclusive.
