This Seiko Astron Solar GPS watch features our Calibre 5X, that offers the most advanced functionality ever.
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 also faster and more intuitive than ever. For example, only three seconds are needed to advance 14 hours from Tokyo to New York time, thanks to the system that moves hour, minute, and seconds 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.
Seiko Astron: the world’s first GPS solar watch which never needs a battery change – powered by light, automatically adjusted to your time zone through the latest GPS technology.
