The first Astron revolution: Quartz
The history of Seiko is the story of innovation. Thanks to a continuous stream of industry-leading innovations over the decades, Seiko established and has maintained its position as a world leader in the technology of time.
On December 25, 1969, Seiko marketed the world's first quartz watch, the Seiko Quartz Astron, and subsequently opened the patents to the world.
In so doing, Seiko set the global standard, and today, most quartz watches use the system Seiko developed. As Seiko’s communication of the day put it: ‘Someday all watches will be made this way.'
