A purist's Grand Seiko with a three-day power reserve
Classic in its form and function, SBGW231 is a purist’s timepiece. It measures just 37.3mm in diameter and 11.6mm in thickness, and it is powered by caliber 9S64, a mechanical manual winding movement with 72 hours of power reserve. The light dial features faceted markers that pair beautifully with the sharp handset and warm dial. The beauty of the decorated movement can be seen through the exhibition case back. Whether your daily attire is jeans and a tee shirt, or a suit and tie, SBGW231 is a versatile option.
