The dial delights the eye with its organic feel and brings to life Grand Seiko’s conception of the Nature of Time. The miniscule but visible variations in the dial’s depth reveal the subtlety of the dark and light tones of the wood grain. The brown tone of the dial perfectly matches the 18k rose gold case to give the watch a gentle and warm feel, and the Zaratsu polished distortion-free mirror finish and the delicate hairline finish alternate on the case to create a quiet and harmonious glow. As is Grand Seiko’s tradition, the SD (Special Dial) mark at the 6 o’clock position denotes the use of gold for the indexes. The hour hand is large in volume and crafted to align exactly with the grooved and prominent hour markers, enhancing the legibility of the time.
The watch is powered by the new Grand Seiko Spring Drive 5 Days Caliber 9RA2, which inherits all the performance characteristics of the Spring Drive Caliber 9RA5 introduced in 2020 in celebration of the 60th anniversary of Grand Seiko, but the power reserve indicator is now visible through the sapphire crystal case back and the beauty of the movement’s finishing is revealed for the first time.
