Astron Solar GPS Chronograph

Seiko Astron: the world’s first GPS solar watch – powered by light, automatically adjusted to your time zone through the latest GPS technology.

This Astron Solar GPS watch features the 5X calibre with advanced functionality.

To enhance the speed and quality of the GPS connection, every component in the GPS module has been re-engineered, the operation of the 5X calibre is faster and more intuitive than ever.
For example, in just three seconds the time can advance 14 hours from Tokyo to New York time, thanks to the system that moves the hour, minute, and second hand independently.
New functions also allow automatic adjustment to Daylight Saving Time and give the wearer the ability to switch the main dial instantly from home to local time and vice versa.
