The Seiko Astron GPS Solar represents a landmark achievement in timekeeping — the world's first GPS solar watch, launched in 2012 as a tribute to the original Astron of 1969. Powered entirely by light through Seiko's proprietary GPS Solar technology (Caliber 8X53), this watch autonomously synchronises to GPS satellites to maintain atomic-clock accuracy anywhere on Earth. With its bold titanium construction, world-time bezel, and distinctly technical dial architecture, the Astron is an instrument for the global traveller who demands precision without compromise. --- Specifications --- Brand: Seiko Series: Astron GPS Solar Reference: 8X53-0AD0-2 Movement: GPS Solar (Caliber 8X53), light-powered, GPS satellite synchronisation Case Material: Titanium Crystal: Sapphire crystal with anti-reflective coating Dial: Dark blue/black, applied luminous baton indices, sub-dials for DST adjustment and time zone selection, date window, "SEIKO GPS SOLAR" and "ASTRON" inscriptions Case Back: Caseback engraved with reference 8X53-0AD0-2 Bracelet: Titanium link bracelet with Seiko butterfly deployment clasp Gender: Men's Period: 2010–2020 Country of Origin: Japan --- Condition Report --- Overall: Good — visible signs of wear commensurate with regular use Case & Bezel: Titanium case shows light hairline scratches on lugs and flanks; ceramic world-time bezel in good condition with no chips Dial & Crystal: Dial in good condition with no damage noted; sapphire crystal shows light surface scratches under raking light Bracelet & Clasp: Titanium bracelet shows light wear on the centre links; deployment clasp functions correctly Functions: GPS solar function, world time display, DST switching — all functions operating as intended --- International Shipping & Customs --- This item will be shipped internationally from Japan, fully insured.
