SEIKO Astron GPS Solar 2025 Black & Neon Orange Limited Edition | SSH183

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.
