Today, a new chapter in the history of Astron GPS Solar technology opens with the launch of an entirely new calibre, 5X, that offers the most advanced functionality ever. The new Astron 5X series is the world's smallest and thinnest* GPS solar watch. It is just 42.9mm in diameter and 12.2mm in depth. 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.
