145 Years of Seiko. Limited to 2,000 Pieces.

The Seiko Astron HAB004 is a landmark timepiece commemorating Seiko's 145th anniversary. Powered by the new GPS Solar Dual-Time Chronograph Caliber 5X63, this limited edition of just 2,000 pieces pairs cutting-edge technology with a design steeped in Seiko heritage.

Blue accents inspired by Seiko Blue — a signature color established in the 1960s and refined over decades — run throughout the dial. The blue seconds track and sub-dials contrast beautifully against the light silver main dial, creating a modern yet refined aesthetic. Sub-dials are arranged in a symmetrical layout made possible by the new movement architecture.

The titanium case features Seiko's quick-change system, allowing effortless swapping between the titanium bracelet and the included exclusive blue-and-white silicone strap with a single push of a button. LIMITED EDITION is engraved on the case back.
