Seiko Astron GPS Solar Watch

 

Seiko released a series of six additional Astron models, inspired by the majesty of the stratosphere above the earth. It is solar power. With just a push 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.
"The new models have a bold, domed sapphire glass, representing the curvature of our planet and the stratosphere that surrounds it."
