Two creations with the gradation colored
dial inspired by the near-future city landscape.

The Lumibrite on both the hands and indexes emits an ethereal blue glow and delivers high night-time legibility.

It is smooth to the touch and easy to wear and yet is scratch resistant thanks to the super-hard coating of the titanium. 
It looks completely at home in the office and yet is 20 bar water resistant. 
It is a watch designed for every aspect of
your life. 

The words “Limited Edition” and the individual watch’s serial number (001/800-800/800) are inscribed on the case back.

Technology of Astron 5X Caliber

Our most advanced ever GPS Solar caliber 5X53

The GPS Solar Caliber 5X53 Dual-Time connects up to twice a day to the GPS network to maintain its precision anywhere in the world. 
It adjusts automatically to Daylight Saving Time and, when the wearer changes time zone, he or she simply pushes a button and the hands move rapidly to the correct local time, thanks to the system that moves the hour, minute, and seconds hands independently. 
In addition, the wearer is able to change the main time display instantly from home to local time and vice versa. 
It is a perfect watch for all international travelers. Travelling can be stressful; Astron makes it just a little less so.

Whatever you’re wearing, wherever you go, the contemporary and avant-garde look of this Astron watch will fit right in.
