A collection that introduced the world’s first GPS solar watch. Astron watches showcase the possibilities in watchmaking technology with watches that connect to the GPS network and adjust to time zones – at the touch of a button. All, to ensure the finest in precision timekeeping wherever you are – across the world.



By connecting to the GPS network, the new Astron adjusts at the touch of a button to your time zone*. And, by taking all the energy it needs from light alone, never needs a battery change.


The Seiko Quartz Astron, released December 25, 1969, was a wristwatch that changed the world. With 100 times the accuracy of a standard mechanical watch, it was the watch that democratised the quartz movement that would eventually bring accuracy to everyone’s wrist.
Four decades on, in 2012, a new watch bearing the Astron name went beyond high accuracy, to make ultra-high accuracy across time zones an everyday reality.
