The first Grand Seiko was manufactured at the Suwa Seikosha factory. The Suwa factory made the Lord Marvel is 1958 and the Crown in 1959, and taking the knowledge from these two high-end calibre projects, created the chronometer grade 3180 which was used in the first Grand Seiko, released in 1960. The Suwa Seikosha company, now Seiko Epson, is based in the Nagano prefecture in central Japan
