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” – The GPS Solar watch “ASTRON”. Please note: Seiko products can only be shipped to addresses within the UK & EU.
