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. --- Specifications --- Brand: Seiko Series: Astron Reference: 8B63-0BH0 Movement: Solar, Calibre 8B63, Radio Wave Control, World Time Case Material: Titanium (black PVD-coated) Crystal: Mineral glass Dial: Black with silver indices, world time subdial, day-date display at 3 o'clock Case Back: Solid, engraved with technical specifications Bracelet: Titanium, multi-link bracelet with fold-over clasp (black PVD-coated) Period: 2010s Country of Origin: Japan --- Condition Report --- Overall: Good — visible signs of wear consistent with regular use Case & Bezel: Black PVD titanium case presents light hairline scratches; PVD coating shows minor wear on edges and bracelet links Dial & Crystal: Dial in good condition; mineral crystal shows faint surface marks Bracelet & Clasp: Titanium bracelet functions correctly; fold-over clasp secure; light wear on PVD finish throughout Functions: Hours, minutes, seconds, world time, radio wave synchronisation, day and date — all functions confirmed operational --- International Shipping & Customs --- International buyers are solely responsible for all import duties, taxes, and customs charges applicable in their country of residence.
