The Legacy of Seiko Astron

Since introducing the world's first GPS Solar watch in 2012, Seiko's Astron line has stood at the forefront of quartz innovation — a fitting continuation of a brand that pioneered quartz timekeeping itself back in 1969. Astron watches sync directly to satellite signals to correct the time zone anywhere on Earth, combining precision engineering with genuine everyday travel utility.

The HAB004 marks one of the most significant Astron releases in Seiko's modern history, created specifically to commemorate 145 years of Japanese watchmaking excellence — a true milestone piece for collectors.

GPS Solar Precision Without Compromise

Even without GPS reception, the Caliber 5X63 movement holds accuracy within ±15 seconds per month — a level of precision that rivals far more expensive calibers. A single full charge powers the watch for roughly six months, stretching to nearly two years in power-save mode, so owners enjoy decades of reliable performance with virtually no maintenance and no battery to ever replace.

Beyond timekeeping, the HAB004 delivers genuine everyday capability: dual-time display, 38-city world time, a perpetual calendar accurate to February 2100, and a high-precision chronograph.

Tool-Free Quick-Change Band System

The HAB004 introduces Seiko's new tool-free quick-change band system, letting owners switch effortlessly between the included titanium bracelet and an exclusive blue-and-white silicone strap — no jeweler or tools needed. Both premium straps come included in the box, giving the watch genuine day-to-evening versatility.
