This particular example features the considerably less common grey sunburst dial, giving the otherwise restrained King Seiko design a distinctive appearance that can shift from light silver-grey to deep charcoal depending on the surrounding light.\u003c\/p\u003e\n\u003cp\u003eThis example remains in original unpolished condition, preserving the sharp case geometry and contrasting surfaces that are such an important part of vintage King Seiko design.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eHistory:\u003c\/strong\u003e\u003cbr\u003eManufactured in 1972 by Seiko’s Suwa factory in Japan, the 5626-7040 belongs to the 56KS generation of King Seiko. The series was developed during an important period for Seiko, when the company’s Suwa and Daini factories were producing increasingly sophisticated mechanical watches and competing at the upper end of the Japanese watch market.\u003c\/p\u003e\n\u003cp\u003eThe 56KS generation combined high-frequency automatic movements with thin cases and the sharply defined geometric styling associated with Seiko during this era. The 5626 variants added both day and date functionality, creating a practical everyday watch while retaining the precision and finishing expected from the King Seiko name.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eSpecifications and Condition:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eOverall: Excellent Vintage Condition\u003cbr\u003eCase: Original Unpolished Condition\u003cbr\u003eCrystal: Clean\u003cbr\u003eDial: Clean, Original Grey Dial\u003cbr\u003eMovement: Just Serviced \u0026amp; Running Well\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eMovement:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eSeiko Caliber 5626 Automatic\u003cbr\u003e28,800 vph \/ 4 Hz\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDimensions:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eApproximately 36.5mm Case Diameter\u003cbr\u003eApproximately 42mm Lug-to-Lug\u003cbr\u003eApproximately 10mm Thickness\u003cbr\u003e18mm Lug Width\u003cbr\u003eStainless Steel Case\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eDesign Details:\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eOriginal Unpolished Case Geometry\u003cbr\u003eContrasting Brushed and Polished Surfaces\u003cbr\u003eKing Seiko Medallion Caseback\u003cbr\u003eHigh-Frequency 56-Series Automatic Movement\u003cbr\u003eManufactured by Suwa Seikosha in 1972\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eClosing Note:\u003c\/strong\u003e\u003cbr\u003eThe 5626-7040 is an excellent representation of King Seiko during the height of Seiko’s mechanical watchmaking in the early 1970s. Its high-frequency automatic movement, sharply faceted case and restrained proportions encapsulate much of the design and engineering philosophy that made vintage King Seiko watches so distinctive.\u003c\/p\u003e\n\u003cp\u003eThis example is particularly compelling for its less commonly encountered grey dial and original unpolished case. With the sharp factory geometry still preserved and the movement having just received a service, it offers an increasingly difficult-to-find combination of originality, condition and mechanical readiness in a vintage 56KS.\u003c\/p\u003e","brand":"JDM Horologist","offers":[{"title":"Default Title","offer_id":50980671291635,"sku":null,"price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0698\/4984\/1907\/files\/62ktCwE_d.webp?v=1788678942","url":"https:\/\/jdmhorologist.net\/products\/hi-beat-king-seiko-5626-7040-grey-dial-gold-medallion-chronometer","provider":"JDM Horologist","version":"1.0","type":"link"}
