About this watch

Each watch in the Elegance Collection offers a unique level of refinement that makes it the ideal choice for those momentous events in life where everything must be flawless, even yet they are all strong and resilient enough to be worn every day. Each timepiece from the Elegance Collection gives its user the comfort and certainty that comes from understanding that they are donning the best. A watch from the Elegance Collection is the ideal accessory for any event, whether it be a wedding in the middle of the day, a reception in the late afternoon, or an evening party. The Japanese style of Grand Seiko and the simplicity of the designs come together in this series to ensure that the elegance is timeless. The dial is deep green in color and is inspired by Byōka, which marks the transition from summer to autumn. The first morning dew appears and the wind feels cool against the skin. It is still the end of August but summer is short in Shizukuishi and the early signs of autumn are in the air. The green of the leaves on the trees is increasingly deep and, with its delicately textured surface, the dial reflects its own special beauty. Powered by the slim, hand-wound movement, Caliber 9S64, this watch is the epitome of simple refinement. The dial is simple and clean but, when viewed through the sapphire case back, the intricate perfection of the engineering of the hand-assembled and adjusted movement is abundantly and satisfyingly clear. Thanks to a long mainspring and a balance both made of a proprietary metals, this watch has a high and stable accuracy rate and a power reserve of 72 hours. Cal. 9S64 is a hand-winding time-only movement from Grand Seiko. It is extremely unusual in the family, lacking a date and being hand-wound. When it was introduced in late 2011 it was the only hand-winding movement in the line until the derived Cal. 9S63 was introduced in 2019.
