Brand: Seiko Model: King Seiko Hi-Beat Reference Number: 5625-7000 Serial Number: 140190 Movement: Automatic Caliber 5625 Dial: Silver sunburst dial with applied faceted indices, displaying noticeable age-related spotting and patina along the outer minute track Case Size: 37 mm (excluding the crown) Case Material: Stainless Steel Production Year: 1971 Condition: Good vintage condition with honest signs of wear and attractive case preservation Dial and Hands The dial features a striking silver sunburst finish that catches the light beautifully, serving as a dynamic backdrop for the applied metallic elements. It is adorned with a prominently applied serif "SEIKO" logo at the top and the distinguished "KS" branding above the six o'clock position, accompanied by the Suwa factory symbol. The hour markers are applied, faceted batons featuring black central inserts, which perfectly match the sharp, polished dauphine hands that also carry black central striping for enhanced legibility. A framed date aperture is positioned at three o'clock. Close visual inspection reveals clear signs of vintage aging; there is noticeable spotting, discoloration, and patina concentrated along the extreme outer edge of the dial near the minute track, most prominently visible between the six and nine o'clock positions. While the central sunburst area remains relatively clean, these outer imperfections represent honest age-related wear typical of vintage timepieces. Case and Crystal Constructed from robust stainless steel, the 37 mm case is a quintessential example of Seiko's Grammar of Design, characterized by its sharp, angular lug profile and flat, mirror-polished surfaces. The case retains strong architectural lines, with the transitions between the brushed upper lug surfaces and the polished flanks remaining distinct. The watch is fitted with its original, deeply knurled crown, proudly signed with the "KS" emblem. Protecting the dial is a clean, flat-profile crystal that sits close to the case, maintaining the watch’s sharp geometric form while providing an unobstructed view of the vintage display beneath. Turning the watch over reveals a solid caseback featuring the highly coveted gold King Seiko medallion, which remains remarkably intact and well-preserved, avoiding the heavy degradation often seen on these models. The caseback engravings, including the reference and serial numbers, remain crisp and fully legible. The case exhibits normal handling marks and superficial scratches consistent with decades of careful wear. Movement Hidden within the front-loading, monocoque-style case is the esteemed Seiko Caliber 5625, an automatic high-beat movement renowned for its sophisticated engineering and smooth sweep. This caliber reflects Seiko's dedication to high-frequency precision during the 1970s. Exhibiting remarkable accuracy and consistency, performing brilliantly for a vintage timepiece. Timegrapher readings indicate a strong performance of +9 to +11 seconds per day with strong amplitude. Strap The watch is currently paired with a period-correct, black textured leather strap. The strap features contrasting white stitching along its edges, complementing the monochromatic aesthetic of the dial and hands, and is secured with a classic stainless steel pin buckle. Condition This King Seiko is presented in good vintage condition. The stainless steel case retains its sharp, factory-intended geometry with only moderate surface wear, while the gold caseback medallion is exceptionally well-preserved. The dial exhibits distinct, localized patina and spotting along the outer perimeter, providing a thoroughly authentic vintage character without compromising the overall legibility or charm of the piece. Dimensions The stainless steel case measures 37 mm in diameter, excluding the signed crown. Remarks A superb opportunity to acquire a legendary piece of Seiko's history. The combination of the iconic 5625-7000 case design, the high-beat caliber, and the beautifully preserved gold medallion makes this a highly compelling acquisition for dedicated collectors of vintage Japanese horology. History Introduced as a direct internal competitor to Grand Seiko, the King Seiko line was created to push the boundaries of mechanical watchmaking in Japan. Produced by the Suwa Seikosha and Daini Seikosha factories, these watches were designed to offer chronometer-level performance housed in cases that adhered strictly to Taro Tanaka's revolutionary design language. The 56KS series, powered by the 5600 family of movements, represents one of the final and most refined iterations of the classic King Seiko lineage before the quartz crisis completely transformed the industry, making it a pivotal artifact of mechanical watchmaking history. / Second Vintage SKU: SEI-SKH-0014
