The watch presents an honest aesthetic with visible signs of history on the case, paired with a remarkably clean dial that enhances its overall appeal. Dial and Hands The silver sunburst dial is preserved in stunning condition, retaining a bright and lustrous finish that catches the light beautifully. It features sharp, applied baton indices with black inlays, matching the faceted dauphine hands which also carry black striping for superior legibility. The text is crisp and intact, proudly displaying the "Chronometer Officially Certified" rating below the Seiko logo, and the Suwa Seikosha logo above six o'clock. A framed date window is positioned at three o'clock, adding practical utility to this elegant face. Case and Crystal The stainless steel case follows Seiko's influential "Grammar of Design" philosophy, characterized by flat surfaces and sharp angles. While the case shows visible surface scratches, nicks, and signs of use throughout the bezel and lugs consistent with its age, it retains its distinct architectural form. The signed "KS" crown is present. A highlight for collectors is the gold "KS" Chronometer medallion on the caseback, which remains intact and legible, adding significant value and charm to this vintage piece. Movement Powering this timepiece is the high-grade Caliber 5625 automatic movement. This Hi-Beat mechanism was designed to offer superior precision and a smooth sweep of the seconds hand. The movement is currently functioning and ready for wear. Timegrapher results indicate a rate of +22s to +30s per day, which indicates a healthy movement and reliable mechanical performance for a vintage watch of this vintage. Strap The watch is fitted with a black leather strap featuring white contrast stitching. This classic pairing complements the monochrome dial and steel case, making it suitable for both casual and dress occasions. The strap is in good condition and ready for immediate use. Condition This King Seiko is in good vintage condition. The most notable signs of age are found on the external case parts, which exhibit scratches and contact marks typical of a watch that has been enjoyed over the decades. However, the dial remains in excellent preservation, free from significant spotting or damage, which largely offsets the external wear. The crystal is clear, allowing for an unobstructed view of the magnificent dial. Dimensions With a case diameter of 36 mm excluding the crown, the watch sits comfortably on the wrist, offering a classic mid-size proportion that defines the vintage dress watch era. The lug design ensures a balanced presence suitable for various wrist sizes. Remarks This reference 5625-7040 is a quintessential example of King Seiko's capability to produce chronometer-grade instruments. The combination of the Hi-Beat movement, the "Officially Certified" dial text, and the gold caseback medallion makes this specific reference highly sought after by enthusiasts of Japanese horology. It is a robust and stylish daily wearer that carries a prestigious history. History King Seiko was established as a competitor to Grand Seiko, created by the Daini Seikosha factory, although later models like this Suwa-produced piece show the technological convergence of the era. During the late 1960s and 70s, these two lines pushed the boundaries of accuracy, culminating in Seiko's dominance at the Swiss observatory trials. The 56KS series, introduced in the late 1960s, brought the convenience of automatic winding to the Hi-Beat platform, marking a high point in mechanical watch production before the quartz revolution. / Second Vintage SKU: SEI-SKX-0002
