This is the second model of Grand Seiko, the "57GS (Self-Dater) Ref. 5722-9990," which elevated Japanese watchmaking technology to global standards.
Born in 1963, the second model inherited the DNA of the first GS but was also a historic masterpiece that embodied the first "date display function (calendar)" and "full-fledged waterproof case" in GS history, designed as a practical machine capable of withstanding harsher daily use.
The greatest appeal of this "5722-9990" lies in its strong, thick lug structure, which symbolizes the second model. The brilliance of its sharply defined multifaceted cuts and the robust cushion-shaped case line formed the foundation of the "Seiko Style" that was later established, making it one of the leading masterpieces of vintage Japanese watches. The dial is a silver dial with an elegant sunburst finish. The thick, three-dimensional bar indexes and sharply polished dolphin hands still exude outstanding legibility and a refined sense of luxury that has not faded.
At its heart is the hand-wound Caliber 5722, which carries on the lineage of the second generation. Of course, it is equipped with a "quick-change calendar function" that allows the date to be instantly corrected by pulling the crown out one click, boasting excellent practicality even today.
【Information on Condition and Specifications】 Over the many years since its manufacture, the crown on this particular piece has been replaced with a "KS (King Seiko) engraved crown" from that era. Additionally, the gold medal (medallion) in the center of the case back is missing, leaving it without the coin.
While the case and dial show minor scratches and age-related changes characteristic of vintage watches, the strong, thick lug edges unique to the 57GS remain firmly intact. Despite the replaced parts and missing medal, this is a highly recommended piece as a "practical vintage GS" that can be used without hesitation in daily life. Please consider the 57GS, which embodies the history of Japanese antique watches, at MORI on this occasion.
