Seiko Astron GPS Solar 2026 Limited Edition SSJ039

A Galaxy on Your Wrist. Limited to 1,500 Pieces.

The Seiko Astron SSJ039 is a 2026 limited edition inspired by the cosmos. A newly developed embossed spiral pattern radiates from the center of the dial, evoking the energy of swirling stars in motion. The dark turquoise dial, infused with glitter, emerges from an all-black case and bracelet to conjure the image of galaxies forming in the pitch-black cosmos.

The case and bracelet are finished with a scratch-resistant hard coating engineered to maintain a deep jet-black sheen over time. The easy-adjust clasp allows for precise bracelet length fine-tuning without tools. Each piece carries a unique serial number engraved on the case back, alongside the LIMITED EDITION designation.

Powered by the GPS Solar Caliber 3X62, this watch self-adjusts via satellite signal and runs for approximately 6 months on a full charge — or up to 2 years in power save mode.
