Brand: Seiko Model: King Seiko Reference Number: 5626-7110 Serial Number: 261307 Movement: Automatic Caliber 5626 Dial: Silver Sunburst Case Size: 36 mm Case Material: Stainless Steel Production Year: 1972 Condition: Excellent vintage condition, with a pristine dial and a sharp, unpolished appearance to the case geometry. Timegrapher result of -64s/day provided. Light wear is present, with only minor handling marks and some faint swirls on the case, in line with careful, respectful use over the years. The caseback engravings remain well-defined and legible, underscoring an overall well-preserved appearance. Dial and Hands The silver sunburst dial is in exceptional condition, preserving its original luster without spotting or significant aging. It features applied multifaceted baton hour markers with black central inlays, matched by sharp dauphine hands also featuring black detailing for high contrast. The applied "SEIKO" and "KS" logos are crisp, and the Day/Date aperture at the 3 o'clock position is framed in steel. Case and Crystal The stainless steel case features the iconic sharp edges and flat surfaces associated with Tanaka's "Grammar of Design." Being a monocoque (front-loading) reference, the case lacks a removable caseback, enhancing its structural integrity and water resistance profile historically. The case retains its factory lines with only minor handling marks and light surface swirls. The crystal is clear and free of significant scratches. The original "KS" signed crown is present. Movement Powered by the robust Caliber 5626 automatic movement, this "Hi-Beat" mechanism operates at 28,800 vibrations per hour, offering a smooth sweep of the seconds hand. The movement features a day and date complication. Current testing shows a deviation of -64s/day, indicating a functioning movement. Strap The watch is fitted with a black leather strap featuring white contrast stitching and a stainless steel buckle, complementing the monochromatic aesthetic of the dial and case. Condition This timepiece is in excellent vintage condition. The dial appears flawless to the naked eye, which is rare for this era. The case preserves its distinctive geometry with sharp bevels, showing only light surface wear consistent with careful usage. The caseback engravings remain deep and completely legible. Dimensions Case diameter is 36 mm excluding the crown. The lug width accommodates standard straps, making it versatile for various styling options. Remarks This 56KS is a superb representation of 1970s Seiko luxury. The combination of the monocoque case, the Hi-Beat movement, and the immaculate dial condition makes this a standout example for collectors seeking a high-grade daily wearer. History King Seiko represented one of the two pinnacles of Seiko's watchmaking in the mid-20th century, produced to drive internal competition and excellence alongside Grand Seiko. The 56 series movements were among the most reliable and widely produced high-grade calibers of the era, manufactured by the Suwa Seikosha factory, symbolizing the golden age of Japanese mechanical watchmaking. / Second Vintage SKU: SEI-SKH-0023
