SEIKO ASTRON is the world's first GPS solar watch.
It requires no external power source and is entirely self-sustaining. Using just the power of light, it connects to the GPS network, and tells time with atomic clock precision, adjusting at the touch of a button to all 40 time zones on earth. Only SEIKO can deliver what the international traveler has long wanted, a watch that understands and adjusts to time zones.
Using just the power of light, Astron adjusts to every time zone on earth at the touch of a button. In 2014 we took Astron even further, introducing a full-function GPS solar chronograph. Now with dual time display, Astron is simply the world's finest GPS solar watch.
