* Case Size: Approximately 25x33 mm * Thickness: Approximately 5 mm * Belt Size: 185 mm, Width: Approximately 18 mm The beauty of this piece lies in the delicate brilliance of the "Sunago dial," which evokes a sense of craftsmanship, and the deep gold texture achieved by the rare 30-micron thick gold plating (SGP30) used in modern times. Of particular note is the engraving on the back cover. This is a long-service award from "Seiko Electronic Industries," a rare item that is rarely seen on the market, with the special background of being presented by the manufacturer to its own employees. The refined, ultra-thin tank case does not interfere with the cuff and elevates the wearer's dignity. This is truly a lifelong treasure, combining historical value and practicality. The high-quality leather belt has been newly replaced. Currently, the watch is running stably and the time is accurate. This is a rare model.
