The brilliance of a “Nova”
A nova is one of Nature’s most remarkable astronomical phenomena. Long thought to be the creation of a new star, a Nova takes the form of a sudden, bright emission of light. With its radial pattern, this dial is inspired by the arrival of a Nova in the night sky.

Ceramic cover on the bezel protects from the scratch.
The sapphire crystal has a super-clear coating that eliminates glare and so delivers optimum visibility from any angle while the Lumibrite on the hands and indexes ensures legibility even in low light conditions.

Technology of Astron 5X Caliber
![](/se-en/-/media/Images/GlobalEn/Seiko/Home/products/astron/2021_limited/astron_7.jpg?h=1125&iar=0&w=2000)
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.
