astron limited
The design motif is “Super-nova”

A super-nova is an astronomical event which is known as explosion of a heavy star. 
A distinctive radial dial pattern on the gradational lame dial and the black case represents a luminous explosion shining strongly in outer space.

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


Blue Lumibrite

The hands and indexes are coated with a layer of Lumibrite to ensure that Astron’s exceptional timekeeping precision can be enjoyed even in low light conditions. The Lumibrite is in a blue that stands out clearly from the dial.

The words “Limited Edition” and the individual serial number are inscribed on the case back.

  • In an actual product, the case back direction might be different from the photograph.

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.
