The Seiko Astron HAB001J1 is a highly advanced GPS Solar timepiece that combines satellite navigation technology with precise timekeeping. At its core is the caliber 5X63, a GPS Solar movement that draws all its energy from light, enabling battery-free continuous operation. With its GPS-controlled time and time zone adjustment, the Seiko Astron HAB001J1 synchronizes to atomic-clock accuracy at the touch of a button and automatically corrects the display to any location worldwide. The signal reception indicator displays the current satellite connection status, making reception easy to monitor at all times.

The case and bracelet are made entirely of titanium, finished with a Super-Hard Coating. This material combination delivers low weight, high scratch resistance and excellent skin compatibility. The sapphire crystal reliably protects the dial against scratches and provides a clear view of the precisely crafted indices and hands. The dial appears structured and high in contrast, complemented by the easily legible large date, a second time zone for the dual time function and a day-night indication. The world time function covers 40 time zones, making this watch an ideal companion for international travel. A perpetual calendar accounts for varying month lengths and leap years, so manual correction is unnecessary.

With a water resistance of 100 meters, the Seiko Astron HAB001J1 is built for everyday wear and active use. The titanium folding clasp ensures a secure and comfortable fit on the wrist. This watch is aimed at technically minded enthusiasts who value functionality, precision and premium materials. At Juwelier Ersay, the Seiko Astron HAB001J1 is available under reference HAB001J1, with payment by invoice or installment. The combination of GPS Solar drive, lightweight titanium and a comprehensive feature set makes this model a compelling representative of the Astron collection.
