ABOUT THIS BRAND
Grand Seiko released its first watch in 1960, challenging the perception that the Swiss were the undisputed masters of fine watchmaking. In the nearly 60 years since the first Grand Seiko, the company has become known the world over for producing some of the most elegantly designed timepieces in the world while developing innovative technologies such as Spring Drive. Even while maintaining its high quality standards, it delivers tons of value in its watches, making it popular with collectors at all levels. In 2017, Grand Seiko became its own brand within Seiko?¡¥s expansive watchmaking portfolio.
Product Description
?A GMT watch that expresses the rich expression of the four seasons of Japan on the dial
Twenty-four solar terms. Japan divides the year into 24 equal parts and incorporates the subtle changes of the seasons into everyday life. Inspired by that, it is a GMT watch that beautifully expresses one energy saving with a dial.
Cold dew dwells in the vegetation, and it is chilly in the morning and evening, and the cold dew deepens in autumn in earnest.
Freed from the hustle and bustle of summer and feeling the calm of the long autumn nights. A dial design inspired by the quiet "Ryoya", where the moon peeking through the clouds looks beautiful and shining. The quiet and smooth movement of the Spring Drive second hand overlaps with the moon quietly crossing the night sky.
