Spring Drive SBGA489

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.
