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
It is a reinforced anti-magnetic model with a sharp bezel, rough vertical lines, and a form that insists on toughness while having a light style.
In addition to the 20 ATM water resistant function and high magnetic resistance of 40,000 A / m, which expands the user's range of action, the screw lock type crown maintains high airtightness and water resistance, and can withstand tough use. It also has durability.
The fit has been improved by keeping the case size thin and small while maintaining a solid shape.
The Lumibright applied to the index is the first Grand Seiko to use two colors, green and blue. In combination with the black dial, which has the effect of preventing reflection when exposed to strong light, it boasts high visibility day and night.
The movement, which is the heart of the watch, is equipped with a thin and highly accurate caliber 9F61, which keeps a reliable time even in harsh environments.
