Hi everyone, Up for sale is a 1971 Seiko King Seiko ref. 5625-7040 from Seiko’s vintage Hi-Beat KS era. It has an original grey sunburst dial that looks classy in person and changes nicely in the light, the dial is marked “Chronometer Officially Certified.” Collector bonus, the gold “KS” medallion on the caseback is still present and in good shape. These are often worn smooth or missing, so it’s great to see this one still clearly showing its King Seiko pedigree. Serviced by my independent watchmaker in July 2025, cleaned and regulated, and it’s currently running, no service papers. It’s still a 50+ year-old movement, please don’t expect modern “near-spec” performance or accuracy, accuracy can vary by position, wear, and temperature. No warranty is offered, the watch is sold as-is as a vintage piece. Quickset date works as it should. As with many vintage Seiko quickset movements, it’s best to avoid changing the date between 9 PM and 3 AM. # Condition **Dial:** Original grey sunburst dial, clean with crisp printing and applied indices, please review the high-res photos. **Case:** 36mm stainless steel case with strong facets, brushed top surfaces visible, honest wear, hairlines, and some scratches on the polished sides from use. **Crystal:** Hardlex crystal, believed to be original, with light scratches, haze from age, mostly visible at certain angles, see photos. **Crown:** Signed “KS” crown, appears correct, winds, sets smoothly, quickset operates properly. **Caseback:** Gold KS medallion present, shows normal aging but intact. **Movement:** Seiko cal. 5625 Hi-Beat automatic.
