Seiko Astron GPS Solar 2024 Limited Editions Express The Infinite Radiance of the Starry Sky

Two new creations inspired by the starry sky at night join the Seiko Astron GPS Solar collection.

The transparent light-blue molded dial evokes the power, beauty, and infinite radiance of the starry sky. The dial’s appearance changes depending on the angle of view.

 

The watch ensures a high level of comfort and legibility thanks to a titanium case with a low center of gravity and a sapphire crystal with a super-clear coating.
