Seiko Astron GPS Solar 2026 Limited Edition HAB005

Crystal Green Radiance. Limited to 1,200 Pieces.

Brilliant by design. The Seiko Astron HAB005 draws its inspiration from the luminous beauty of green quartz — a stone prized for its clarity, depth, and natural radiance. A newly developed pressed pattern dial in Crystal Green captures the sparkling facets of quartz crystal, emitting a fresh, radiant glow that shifts with every angle of light. This is precision timekeeping elevated to wearable art.

Powered by the GPS Solar Caliber 5X63, the HAB005 automatically syncs to GPS satellites for flawless, atomic-level accuracy anywhere on Earth. The 43.4mm super-hard coated titanium case is featherlight yet exceptionally durable, while the innovative quick-change strap system lets you switch effortlessly between the titanium bracelet and the included exclusive black silicone strap — no tools required, just press and go. As a special package exclusive to this limited edition, the watch arrives in a special nylon presentation box, with a serial number and LIMITED EDITION designation engraved on the screw case back.

Only 1,200 pieces exist worldwide. Crystal Green. Quartz-inspired. Unmistakably Astron.
