Grand Seiko History
Grand Seiko traces its history back to 1960 when Suwa Seikosha released the first Grand Seiko model, the ref. J14070. The new Grand Seiko Cal. 3180 had an accuracy within +12 to -3 seconds a day and a power reserve of 45 hours. This was followed by the 57GS in 1963, 44GS in 1966, 62GS in 1966, 61GS in 1968, 45GS in 1968, 19GS (in 1968, for women), and finally the 56GS in 1970. The Grand Seiko competed directly with Daini Seikosha's King Seiko and was replaced by its adjacent brand, the Grand Quartz line, in 1975 when quartz rose to the top of Seiko's catalogue - making a comeback in the early 1980s.
Seiko was founded as a watch store in 1881 by Kintaro Hattori in Tokyo. By the 1890s it was producing both clocks and pocket watches as Seikosha. And in 1913 Seiko produced Japan's first wristwatch, the Seiko Laurel. Seiko had beat out several other Japanese companies, including other Tokyo clock companies like Tokyo Clock Co. and Japan Pocket Watch Manufacturing Co. By the mid-20th century Seiko produced some of its most important wristwatches that set the stage for its future. In the early 1950s Seiko produced the Seiko Super which then became the Marvel. And in 1960 Seiko released the first Grand Seiko. This marked the beginning of not only the Grand Seiko but also the King Seiko and Lord Matic lines to follow.
Then, in 1969, Seiko released the Astron, the watch that would upend the Swiss watchmaking industry. Throughout the 1970s and 1980s Seiko continues to produced extraordinary quartz watches, along with many legendary vintage Seiko dive watches. In modern times Seiko continues to innovate, especially through its Grand Seiko brand.
