• The world’s firstGPS solar watch

    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.

    *For the time zone information of your caliber, please refer to here. If there are changes in the region/time zone, manual time zone selection may be required.

  • Dynamic movementof the hands,which can sensethe connectionwith satellites

    When GPS signals are received, the second hand starts moving, indicates the number of satellites, and then displays the current time.
    It is an emotional moment, feeling an identification with GPS satellites 20000km away.

  • Automatic Timeadjustment

    Whenever the dial is exposed to bright light, the watch automatically receives GPS signals. When the watch is concealed under a sleeve and the dial cannot receive enough light, the watch stores the time of the previous successful manual time adjustment or time zone adjustment, and automatically starts time adjustment at the same time.

  • High receptionperformanceof an exclusiveSeiko ring antenna

    An exclusive Seiko ring antenna placed under the dial ring is suitable for automatic reception as it can easily receive signals regardless of posture.



The Astron Story

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.
-Someday all watches will be made this way.
With the delivery of this powerful statement, as a result, Seiko set the global standard, and today, most quartz watches use the system Seiko developed.

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 the new Seiko Astron, the world’s first GPS solar watch, so dramatically demonstrates.
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 progress of Astron never stops. Astron has continued to pursue “the ultimate wristwatch.”
