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 hand-wound spring drive model with the image of "Omiwatari"
This dial model is based on the image of the mysterious natural phenomenon "Omiwatari" that occurs when the entire surface freezes in the middle of winter at Lake Suwa, which is close to the Takumi Kobo in Shinshu, where the Spring Drive model was born. The movement is made by Takumi Kobo in Shinshu and is equipped with a hand-wound spring drive caliber "9R31" that lasts about 72 hours. The dual spring barrel which stacks two thin and long power-springs in parallel is adopted. It also features the appearance of a beautiful movement with a hairline finish.
