About Seiko Astron
Seiko predicted that someday most watches would use the quartz technology in the Astron, and that prediction turned out to be true. The original Seiko Astron in 1969 was the first quartz wristwatch to see commercial production. The second incarnation promises to be a similar trendsetter. This Seiko is an analog solar-powered watch with GPS. Its GPS radio links to geosynchronous satellites to automatically set the time to the wearer's local time zone, which means your watch stays accurate wherever you are in the world. While this Seiko watch uses light energy to power itself, you need to keep active in a Seiko Kinetic watch because it requires the wearer's movement to stay charged. There is no doubt that Seiko makes some of the most innovative watches available and the Astron is the only watch of its kind. For a watch that never fails to keep time, choose the Seiko Astron from among the wide selection of timepieces offered by trusted sellers on eBay.
