Seiko Astron GPS Solar 2026 Limited Edition SSH187J1 - Cosmic Energy on the Wrist

With the Astron GPS Solar 2026 Limited Edition SSH187, Seiko takes you into the depths of the universe. The newly developed dial with an embossed spiral pattern spreads outward from the center, conveying the dynamics of swirling stars. Combined with the dark turquoise, finely shimmering dial, it creates the impression of a mysterious galaxy emerging from the deep black cosmos.

High-tech Meets Futuristic Aesthetics

The case and bracelet are entirely black and feature a scratch-resistant Super Hard Coating. This permanently preserves the intense, dark shine and emphasizes the watch’s modern character. The clear lines, balanced case size, and integrated bracelet provide a powerful yet elegant presence. Thanks to the finely adjustable clasp system, the titanium bracelet can be precisely fitted, offering high comfort for everyday wear and travel.
