Seiko Superior History
The Seiko Superior Quartz was the most accurate and most expensive of the Seiko Quartz line in the 1970s. Starting with the Seiko Superior Cal. 3883 in 1974 and the Superior Cal. 4883 in 1976, the line evolved into the Superior Twin Quartz Cal. 9983 in 1978. This was above the Seiko Grand Quartz and King Quartz - something like the VFA or Cal. 6186 equivalent to the mechanical Grand Seikos that were produced until 1975.
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 produce extraordinary quartz watches, along with many legendary vintage Seiko dive watches. In modern times Seiko continues to innovate, especially through its Grand Seiko brand.
