--- Introduction --- The SEIKO Astron GPS Solar is the modern heir to a name that changed watchmaking in 1969, when the original Quartz Astron was introduced. Launched in 2012, this line brought satellite timekeeping to the wrist, drawing its power from light and receiving signals from GPS satellites. This reference presents the collection's bold, purposeful character: a black ceramic bezel engraved with world cities, a layered black dial that fades into a deep grey centre, and a dedicated 24-hour sub-dial. It is a commanding, technically distinguished piece from Japan, supplied here with its box and booklets and offered in very good condition. --- Specifications --- Brand: SEIKO Series: Astron GPS Solar Reference: 7X52-0AE0 Movement: Calibre 7X52, GPS solar quartz Case Material: Stainless steel with black ceramic bezel Crystal: Sapphire (estimated) Dial: Black with grey gradient centre, applied luminous markers, UTC time-difference scale, date at 3 o'clock, 24-hour sub-dial Case Back: Stainless steel, engraved SEIKO GPS SOLAR, 7X52-0AE0, WATER RESISTANT 10 BAR and MADE IN JAPAN Bracelet: Stainless steel link bracelet with brushed and polished surfaces, signed SEIKO fold-over clasp with push-button release Period: 2010-2020 (estimated) Country of Origin: Japan --- Condition Report --- Overall: Very good pre-owned condition with light signs of use.
