Movement has been adjusted and performs strongly, as shown in the timegrapher result. Dial and Hands The dial features a classic silver sunburst finish that serves as a backdrop for exceptional mid-century Seiko typography and dial furniture. It proudly displays the applied "SEIKO" logo beneath the 12 o'clock position, accompanied by the printed "Chronometer" designation, while the lower half features the elegant Gothic "Grand Seiko" script alongside "Diashock 35 jewels". The applied, highly faceted baton indices and the sharp dauphine hands both feature distinctive black central stripes, a thoughtful design element intended to maximize legibility against the radiant dial. In terms of condition, the dial exhibits a distinct, scattered patina with visible spotting and localized staining, particularly concentrated around the outer perimeter and the lower half. This age-consistent mottling provides a warm, historic character to the piece, while the polished hands and applied markers remain sharp and highly reflective. A framed date aperture sits cleanly at the three o'clock position. Case and Crystal The 36mm stainless steel case showcases thick, robust lugs with a distinct faceted profile. While the case retains its handsome proportions and strong presence on the wrist, the lug chamfers and edges show slight softening indicative of honest vintage wear and historical polishing. The smooth polished bezel frames a domed acrylic crystal that remains clear and highly presentable, offering an unobstructed view of the dial. The coarse-knurled crown is correctly signed with the classic "W SEIKO" designation. Turning the watch over reveals a screw-down caseback highlighted by the legendary gold Grand Seiko lion medallion. The medallion remains deeply struck and beautifully preserved, surrounded by crisp reference and serial number engravings. Movement Powering this timepiece is the beautifully finished manual-winding Caliber 5722A, proudly engraved with its 35-jewel count and "GRAND SEIKO CHRONOMETER" designation alongside the movement serial number 514690.

The movement presents exceptionally cleanly under close inspection. Exhibiting remarkable accuracy and consistency, performing brilliantly for a vintage timepiece. The timegrapher results show an excellent deviation of +6 to +8 seconds per day with strong amplitude. Movement has been adjusted and performs strongly, as shown in the timegrapher result. Strap The watch is fitted with a sophisticated dark brown leather strap featuring a classic crocodilian grain pattern. It is secured by a standard stainless steel pin buckle and complements the warm tones of the dial patina and the gold caseback medallion perfectly. Condition This Grand Seiko is presented in good vintage condition. The case shows normal handling marks, light surface scratches, and softened edges consistent with decades of careful use. The dial displays prominent, visible spotting and a mottled patina across the sunburst surface, giving it a distinct vintage identity without compromising the sharp, highly polished dial furniture. The caseback medallion is remarkably crisp, and the internal movement presents in outstanding visual and mechanical shape. Dimensions Case Size: 36 mm Remarks This is a superb opportunity to acquire a legendary reference from the golden era of Japanese watchmaking. The 5722-9990 is a cornerstone of any serious Grand Seiko collection, offering a beautiful blend of robust mechanical engineering, historical significance, and mid-century elegance. History Introduced in the mid-1960s, the 57GS series marked the second generation of Grand Seiko and the first to feature a date complication. It was a period of intense internal competition and rapid technological advancement at Seiko, with the Suwa Seikosha factory pushing the boundaries of accuracy. The chronometer designation on the dial and the gold lion medallion on the caseback were Seiko's proud declarations that their timepieces could rival the strictest European chronometry standards. The robust case design of the 57GS also began to hint at the sharp, flat-surfaced "Grammar of Design" principles that Taro Tanaka would soon formalize, making this model an important transitional piece in the evolution of Seiko's aesthetic identity. / Second Vintage SKU: SEI-SCG-0001
