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 them popular with collectors at all levels. In 2017, Grand Seiko became its own brand within Seiko??£¤s expansive watchmaking portfolio.

It differs from the accuracy (mobile accuracy) in the environment where the customer actually uses it. In addition, due to the characteristics of the mechanical model, depending on the conditions of use (carrying time, temperature, arm movement, strong shock or vibration), the above accuracy range may be exceeded.
