The world’s first GPS solar watch. By connecting to the GPS network, the 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.
Astron GPS Solar communicates with the GPS network and adjusts to your time zone anywhere on Earth. With high speed time zone adjustment and the time transfer function, the new Astron 5X is the most advanced in history.
