Seiko - Astron GPS Solar 2025 Chronograph Limited Edition - SSH171

Limited edition of 1,500 pieces

Seiko Astron GPS Solar 2025 Limited Edition Inspired by cherry blossoms blooming under the stars. A beautiful scene of a starry sky and cherry blossoms dancing in the wind is expressed in the glittering purple gradation dial and all-black case and bracelet. The outer circumference of the dial is decorated with a pattern resembling star trails. The case and bracelet are finished with a scratch-resistant hard coating that maintains its jet-black sheen. The adjustment system for the clasp allows easy fine-tuning of the bracelet length.
