AI-assisted summary

Description from the seller

--- Introduction ---
When Seiko unveiled the Astron GPS Solar in 2012, it marked the first wristwatch in the world able to locate itself by satellite and adjust to any of the time zones on earth, powered by nothing but light. This first-generation reference 7X52-0AA0 presents that landmark calibre in its most purposeful form: a broad titanium case crowned by a black ceramic bezel, a dense black dial carrying the world-city ring, and a matching titanium bracelet. Fifty years after Seiko brought quartz to the wrist, the Astron restated the same ambition, and it remains one of the most technically significant Japanese watches of the modern era. The lot is offered with its original outer box and the Basic Manual.

--- Condition Report ---
Overall: Good - visible signs of wear. A worn but sound example that has clearly seen regular service on the wrist and remains complete and presentable.
Case & Bezel: The titanium case shows visible hairline scratches and small nicks across the brushed and polished surfaces, most noticeably on the caseband and lug edges. The black ceramic bezel is intact and retains its gloss, with only minor marks.
Dial & Crystal: The black dial is clean and legible, with all hands, subdials and applied markers present and correct. The sapphire crystal is clear and free of chips or cracks.
Bracelet & Clasp: The titanium bracelet is complete and closes securely, showing scratches and light dulling of the finish across the links and on the clasp cover, consistent with everyday wear.
Functions: GPS solar quartz movement, running at the time of listing. Time and calendar functions respond correctly. Please note that the original outer box is heavily worn and scuffed, as pictured. Water resistance has not been tested and cannot be guaranteed; a service check is recommended before any exposure to water.
