Description from the seller
The Seiko Astron represents a landmark in horology — introduced as the world's first GPS solar watch, the Astron line brings satellite-synchronised precision to an elegantly engineered package. This example, Reference 8B63-0BH0, is powered by the Calibre 8B63 radio wave solar movement, combining solar charging with multi-band radio wave reception for automatic time correction. The all-black titanium case and bracelet present a commanding, contemporary aesthetic, complemented by a deep navy-black dial with a world time subdial and day-date complication. Titanium construction keeps the watch surprisingly light on the wrist, enhancing daily wearability.
