With its preserved gold caseback medallion and sharp monocoque case design, this timepiece offers collectors a blend of precision engineering and sophisticated vintage aesthetics that rivals its Grand Seiko counterparts. Brand: Seiko Model: King Seiko Hi-Beat Chronometer Reference Number: 5626-7060 Serial Number: 230532 Movement: Automatic Caliber 5626 Dial: Silver Sunburst Case Size: 36 mm (excluding the crown) Case Material: Stainless Steel Production Year: 1972 Condition: Excellent vintage condition. The watch presents beautifully with a very clean dial and a sharp case that retains its original definition, accompanied by a preserved gold medallion on the caseback. Dial and Hands The silver sunburst dial is in exceptional condition, radiating a clean and sophisticated luster. It features applied multifaceted baton indices with black onyx-style inlays that match the hands, creating excellent contrast and legibility. The text is crisp, proudly stating "Chronometer Officially Certified" and displaying the applied "KS" and Seiko logos. A framed day-date window is positioned at 3 o'clock, featuring a dual-language calendar wheel. The slender second hand sweeps smoothly, a hallmark of the high-beat movement, while the Suwa factory whirlpool logo sits above the 6 o'clock position. Case and Crystal The stainless steel case follows a classic monocoque-style design, as indicated by the "Open Thru Glass" engraving on the back, which was engineered for superior water and dust resistance. The case lines remain distinct and the surfaces show honest wear consistent with careful usage. The crown is the original "KS" signed version. A highlight of this specific piece is the gold "Seiko KS Chronometer" medallion on the caseback, which remains intact and clearly visible, a detail often lost or damaged on surviving examples. The crystal is clear and free of distracting marks. Movement Powering this watch is the highly regarded Seiko Caliber 5626, a high-beat automatic movement operating at 28,800 vibrations per hour. This "Hi-Beat" specification was designed to ensure higher precision and stability. The movement is running within vintage tolerances, offering reliable vintage performance and a smooth sweep of the seconds hand. Strap The watch is fitted with a classic black leather strap featuring an embossed alligator grain pattern. The strap is in good condition, soft and pliable, and complements the formal, dress-watch aesthetic of the King Seiko perfectly. It is secured by a silver-tone buckle. Condition This timepiece is in excellent vintage condition. The dial is remarkably preserved, showing virtually no signs of aging. The case shows light surface scratches typical of a watch from the early 1970s but retains its structural integrity and sharp geometry. The gold medallion on the back exhibits some surface scratches but is fully present and legible. Dimensions The case measures 36 mm in diameter excluding the crown, a classic proportion that sits elegantly on the wrist. The lug width and case profile provide a balanced presence suitable for both formal and casual wear. Remarks The King Seiko 5626-7060 is a significant reference for collectors, bridging the gap between high-precision tool watches and luxury dress pieces. The presence of the "Chronometer Officially Certified" text and the intact gold medallion significantly elevates the desirability of this specific example. It stands as a testament to Seiko's ability to produce world-class chronometers during the 1970s. History Produced in March 1972, this watch emerged during the height of the "watch wars" between Seiko's Daini and Suwa factories. King Seiko was often seen as the internal rival to Grand Seiko, offering comparable finishing and movement quality. The 56KS series is particularly noted for bringing high-beat precision and chronometer standards to a wider audience, playing a crucial role in establishing Seiko's reputation as a manufacture capable of beating Swiss observatories at their own game.
