Seiko 5 History
The first Seiko 5 was released in 1963, the Seiko Sportsmatic 5. It was renowned for its durability and practicality – it was automatic, water resistant, featured a day-date display, three hands, and Seiko's Magic Lever. Seiko produced another notable piece in the collection in 1969, the Seiko 5 Sports Speed-Timer, one of the first automatic chronographs ever. A notable vintage Seiko chronograph. All of Seiko 5s share five attributes aimed at improving their functionality as a sports watches: water resistance, automatic winding, a day/date display, a sports-intended case/bracelet, and a recessed crown at 4.
Seiko 5 Actus History
The Seiko 5 Actus first appeared in the JDM Seiko catalogue in 1970. They were a new 'affordable' line for Seiko, with automatic movements and steel bracelets. There was both the Seiko 5 Actus and the regular Actus. The Seiko 5 Actus came as the 7019, the 6106 (SS), and the SilverWave 6306 versions, among others. The hacking feature on the 6106 stops the seconds hand when the crown is pulled out, allowing the user to adjust the time with precision down to the second. This would have been useful for pilots that used it to synchronize their manoeuvres with their comrades. The 6106 movement was actually released in the late 1960s and produced until the mid-1970s. While the Seiko 5 Actus last appeared in the 1976 JDM catalogue, the Seiko Actus continued to be sold into the late 1970s and used the 6306 ‘SS’ movement.
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.
