Seiko Astron GPS Solar 2025 Limited Edition
A limited-edition model that expresses the near future with dynamic and unique colouring.

The dial features a new horizontal pattern with intermittent lines, evoking the image of light traveling at high speed.
The two-layered bezel combines ceramic components with a polygonal decorative edge, creating a special design unique to this limited-edition model.

Black ceramic is used for the bezel and the central row of the bracelet, and neon orange accents are applied to various parts, creating a sporty design.
The adjustment system for the clasp allows easy fine-tuning of the bracelet’s length.
