Introduction The Seiko Astron GPS Solar represents a landmark achievement in horology - the world's first GPS solar watch, introduced by Seiko in 2012. This particular reference is powered by the caliber 7X52, which automatically adjusts to any of the 39 time zones on Earth by receiving GPS signals from satellites. Combined with solar charging, this timepiece requires no battery replacement and delivers atomic-clock precision anywhere on the planet. Seiko's Astron line carries a legacy that dates back to 1969, when the brand revolutionized watchmaking with the world's first quartz wristwatch.

The original 1969 Astron changed the industry forever, and Seiko revived the name in 2012 for its groundbreaking GPS technology.
