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.'

The second Astron revolution: GPS Solar

For Seiko, the story of quartz is still only just beginning. Thanks to Seiko's relentless drive for innovation, new possibilities in watch technology continue to open up, as each new generation of Seiko Astron GPS Solar has so amply demonstrated.
Seiko has, once again, pushed back the boundaries of what a watch can deliver and has set a new world standard in electronic watchmaking. The story of Astron never stops.



By connecting to the GPS network, the new Astron adjusts at the touch of a button to your time zone*. And, by taking all the energy it needs from light alone, never needs a battery change.


The Seiko Quartz Astron, released December 25, 1969, was a wristwatch that changed the world. With 100 times the accuracy of a standard mechanical watch, it was the watch that democratised the quartz movement that would eventually bring accuracy within everyone’s.
