About the Seiko Astron SSH117J1:

The Seiko Astron is the world's first GPS-enabled sundial: it takes the energy it needs from light without needing a battery and adjusts 2 times a day to its time zone at the touch of a button. The 5x series is the most advanced of all. Its caliber is time adjustment at high speed.  Switch the display of start and destination times between the primary and secondary spheres by simultaneously pressing the buttons at 2 and 4. The size of the 5x series is compact. The SSH117J1's case and bracelet  are made of titanium.  Its sapphire crystal is high definition with "super clear" treatment patented by Seiko, a super-transparent coating that eliminates glare and offers optimal visibility from any angle.

With its radial pattern, this dial is inspired by Nova. A nova is a cataclysmic astronomical event that causes the sudden appearance of an apparent "new" star.
