The Seiko Astron collection is the world's first GPS solar watch. By connecting to the GPS network, the new Astron sets your time zone at the touch of a button, and since all the necessary power is supplied solely by light, battery changes are never necessary. The Caliber 5X is the world's most advanced solar caliber. To improve the speed and quality of the GPS connection, every component in the GPS module has been redesigned. Using three independent high-speed motors for the hour, minute, and second hands, the Caliber 5X requires only three seconds under ideal conditions to change from one time zone to the next.
