A refined vintage wristwatch from Seiko’s distinguished SilverWave line, reference 5932-5280, presented in a sophisticated two-tone configuration. This quartz model combines classical dial aesthetics with the distinctive geometric case design characteristic of its era. Produced in December 1981, as indicated by the serial number, this example reflects Seiko’s technical precision during a period of strong design identity. The caseback and dial bear the lightning bolt emblem associated with Daini Seikosha (Kameido), one of Seiko’s principal manufacturing facilities at the time. Stylistically, the watch reflects the “luxury sport” aesthetic that emerged in the late 1970s and early 1980s. The octagonal case with integrated bracelet embodies the geometric design language popular during this period. The two-tone construction, combining stainless steel with a gold-plated bezel (SGP), further enhances its balanced and versatile appearance. The SilverWave emblem, visible on the dial and caseback, denotes Seiko’s early waterproof sport-oriented line, a precursor to later professional collections. ━━━━━━━━━━━━━━━━━━ Specifications　WATCH ━━━━━━━━━━━━━━━━━━ Case Diameter: 36 mm Case Thickness: 8 mm Lug Width: 16 mm Wrist Size: up to approximately 18 cm Movement: Quartz Material: Stainless steel case with SGP (gold-plated) bezel Crystal: Mineral glass Water Resistance: Not specified Origin: Japan The watch measures approximately 36 mm in diameter with a thickness of 8 mm and a lug width of 16 mm, and it fits wrists up to approximately 18 cm.
