Seiko 7A28 History
The Seiko 7A28 analog quartz chronograph movement is known as the world's first analog quartz chronograph. It was first released in the early 1980s and has been produced in several iterations since, including updated calibers like the Seiko Cal. 7A38 and Seiko Cal. 7A48. A number of famous quartz chronograph models using the Cal. 7A28 also exist, like the 'Speedmaster' 7A28-7049 or other similar 'Speedmaster' models, the Seiko Yacht Timer 7A28-7090, and the famous Seiko Giugiaro chronographs, namely the 7A28-7000 or the 'Ripley', worn by Ellen Ripley in James Cameron's 1986 hit Alien. The Seiko 7A28 chronograph is the kind of vintage Seiko that really reminds you of what made Seiko so special in the period that quartz was especially popular, between the 1970s and 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.
