This limited edition commemorates the 20th anniversary of Grand Seiko's original Spring Drive movement, Caliber 9R, which was created in 2004. The Hot aka mountain range rises majestically in the Shinshu region of central Japan, the birthplace of all Grand Seiko Spring Drive creations. With its bright red dial, the second Spring Drive creation captures the Hot aka mountain range and the brilliant autumn leaves bathed in golden morning sunlight. The watch’s recessed power-reserve indicator in copper pink adds depth while enhancing legibility and providing a point of contrast to the design. The rose gold color of the GS logo and the vibrancy of the red dial beautifully evoke the mesmerizing transition of changing leaves in all their autumnal glory.
