Introducing a new Seiko Astron design, inspired by the curvature of the Earth.

Following the unprecedented and continuing success of the first Seiko Astron collection, Seiko Watch Corporation is now releasing a special series of six additional Astron models whose design is inspired by the majesty of the stratosphere above the earth. The new models have a bold, domed sapphire glass, representing the curvature of our planet and the stratosphere that surrounds it.


Seiko Astron GPS Solar. The world’s only GPS Solar watch

Until the new Astron, no watch could adjust automatically to different time zones. Now, thanks to the creation of an ultra-low consumption GPS module, Seiko has succeeded in harnessing the GPS network so that Astron adjusts to 39 time zones across the globe, using just the power of light. With only one touch of a button, Seiko Astron receives signals from four or more GPS satellites to automatically determine one’s location and set the correct local time and date anywhere on the planet. Seiko Astron GPS Solar is a revolution in wristwatches just as significant as that which was started by its celebrated 1969 predecessor, the Seiko Quartz Astron, the world’s first quartz watch. In just a few short months, the Seiko Astron GPS Solar collection has made a lasting impact on the watch industry and is changing the world’s expectations of what a watch should be.

The new Astron design. Celebrating the beauty of our planet

Imagine our planet as you would see it from space; a blue sphere floating freely, silently and beautifully in its graceful orbit. This is the idea that has inspired the new design and it was realized by the creation of a dome-shaped sapphire glass. Sapphire is very difficult to fashion because of its hardness; it is a material whose hardness is second only to diamond. Over 10 hours of polishing is required to create and polish the glass on the new Astron design into a smooth, curved surface. The light from the luminous paint underneath the glass creates a sense of the earth’s atmosphere through the sapphire. The effect is dazzling. The spherical surface extends from the glass to the case and to the silicon band, creating the overall illusion that the watch is like our Earth moving through space. What better design could there be for a watch that talks to the stars?


The watch dial, a globe seen from above

The time displayed by Astron comes from the UTC* signal sent out from the atomic clocks in each GPS satellite. The design of the dial expresses this visually, by showing the time as if one were viewing a globe from above the north pole, with the city codes and their offset times aligned with the map. The city codes are easy to read in a bold font along the edge of the dial ring through the curved sapphire glass.

* Coordinated Universal Time (UTC): Official world time based on International Atomic Time (TAI) with an adjustment for leap seconds. Standard time around the world conforms to UTC.
