Grand Seiko

The concept Seiko designed for Grand Seiko is to create an “ideal watch”, which means “no less than the best luxury watch in the world.” For the company, this means that Grand Seiko should have its own unique style that will arouse the high-end market Vibes. Specifically, Seiko hopes that Seiko’s style is suitable for both casual and formal wear. In 1960, the company’s Suwa Seikosha department created the first Grand Seiko watch, which was focused on quality mechanisms. It was not until the release of the 44GS movement in 1967 that designer Taka Tanaka’s “Grand Seiko Style” defined the style of the series and all future Seiko products.

The Seiko series is also highly rated for its superb craftsmanship, especially the traditional method of making watches. Each Grand Seiko watch is hand polished using “Zaratsu” technology. Japanese watchmakers use this traditional polishing method to make watches that have a mirror finish and are not deformed.
