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
?High-precision mechanical that gives a feeling of the next generation to you who are active on the world stage
It is a model equipped with caliber 9S86 with GMT function while maintaining the performance of the self-winding mechanical high beat 36000 movement that is resistant to disturbance and achieves high precision when carried.
The 24-hour scale on the dial and the blue steel GMT hand allow you to view the time in another region with a different time zone.
The exterior design, which was created by modernizing the "brilliantly shining clock" defined by the original design philosophy "Seiko Style" established by the "44GS" released in 1967, often uses a mirror-finished surface without distortion. I am.
The dial adopts the "Mt. Iwate pattern" that expresses the magnificent surface of Mt. Iwate, which is desired from Shizukuishi Luxury Watch Studio, which is responsible for Grand Seiko's mechanical watches, and achieves a delicate, sharpened and beautiful finish.
