The case form, which harmonizes the sharpness and soft texture typical of Grand Seiko, shines like a jewel thanks to the mirror surface created by an outstanding polishing craftsman.
The dual-curved sapphire glass is thoroughly polished from both sides to create a distortion-free dome shape. In addition, the dial has a raised dome shape in the center, giving it a gentle and soft look typical of a mechanical watch.
The minute hand and power reserve indicator hand are gently curved to follow the dial. The hands, which have been carefully processed one by one by craftsmen, harmonize with the rich curved lines of the case, sapphire glass, and dial, enhancing the sense of unity.
Equipped with Caliber 9S63 with a small second hand and power reserve indicator. This is Grand Seiko's first hand-wound mechanical movement in eight years.
