The dial of this dress watch is in a deep burgundy color that is inspired by the rich autumn colors of Boshū, the ‘sekki’ or season when the trees that surround the Grand Seiko Studio Shizukuishi in northern Japan change in hue and announce that winter is just around the corner.
Powered by the slim, hand-wound movement, Caliber 9S64, this refined timepiece is simple in its overall design but so exquisitely finished that its details are forever fascinating. The dial is open and clean but, when viewed through the sapphire case back, the intricate perfection of the hand-assembled and adjusted movement is abundantly and satisfyingly clear. Thanks to a long mainspring and a balance, both made of proprietary SPRON alloys, this watch has a high and stable accuracy rate and a power reserve of 72 hours.
