Seiko launches new titanium Astron GPS solar watches as part of limited-edition series
Seiko has added two new limited-edition watches to its premium Astron GPS Solar lineup. The HAB005J1 and HAB006J1 are pretty much identical watches, differing only in their dial colors. The HAB006J1 will be available first in June 2026, followed by the HAB005J1 in July. Both production runs are restricted to 1,200 pieces worldwide.
Both models utilize a titanium case treated with a super-hard coating. The dimensions measure 43.4 mm in diameter, with a thickness of 12.4 mm and a lug-to-lug distance of 50 mm. A sapphire crystal protects the dial. The case provides a water resistance of 10 bar and magnetic resistance up to 4,800 A/m. A quick-change system means owners can swap between the standard titanium bracelet and the included black silicone strap without using any tools.
The visual variation between the two references is only in the pressed dial pattern. The HAB005J1 uses a green colorway, while the HAB006J1 features a unique pinkish-purple finish. Inside both cases is the Caliber 5X63 GPS solar movement. This high-end caliber adjusts to current time zones via GPS signals and includes a perpetual calendar, dual-time function, chronograph, and a power reserve indicator. It operates for approximately six months on a full charge.
Pricing is the same across both references. In EU markets, the HAB005J1 and HAB006J1 are priced at EUR 3,000.00 (~$3,493). Pricing in other regions like Norway lands at NOK 37,950.00 (~$4,092). Each watch ships in a presentation box alongside the secondary strap.
