Seiko Astron GPS Solar Limited Edition SSH183J1

Seiko Astron GPS Solar 2025 Limited Edition - For Those Ahead of Their Time

Future Meets Precision

With the models SSH183J1 and SSH185J1, Seiko brings new impulses to the Astron collection. Under the design concept "Solidity," both models stand for a clear, powerful language of form and modern technical sophistication. Smooth transitions from the case through the lugs to the bracelet create a harmonious overall appearance with a distinctive silhouette.

Design Inspired by the Speed of Light

The horizontally textured dial with interrupted lines evokes light rays gliding through space at high speed. The two-layer bezel combines ceramic with an exclusive polygonal decorative edge developed specifically for this Limited Edition. Neon orange (SSH183J1) and light green (SSH185J1) provide a bold contrast and give the watches a sporty, avant-garde character.

Technology in Perfection

The case made of super-hard-coated titanium is both robust and lightweight, while black ceramic elements in the middle link row of the titanium bracelet emphasize the technical look. Maximum wearing comfort is ensured by the micro-adjustable safety folding clasp. The GPS solar technology guarantees precise time adjustment worldwide – without any battery changes.
