An elegant Seiko King Quartz, reference 5856-8060, manufactured in January 1978 — a fine example of Seiko’s late-1970s precision design. Powered by the high-grade Cal.5856 quartz movement, a flagship of Seiko’s pursuit of accuracy during the “Quartz Revolution.” The King Quartz line represented the pinnacle of Seiko’s craftsmanship — combining chronometer-level precision, solid stainless steel construction, and the sharp, architectural case design that defined late 1970s Japanese watchmaking. Unlike most quartz watches of its time, the King Quartz was built to the same standards of quality and finishing as Seiko’s finest mechanical watches. The vertical brushed silver dial beautifully reflects light across its surface, with faceted hour markers and a bilingual day-date display (English/Japanese). Case diameter: 35.0 mm (excluding crown). Fitted with a brand-new genuine leather strap (18 mm) that complements its refined tone. Movement running at the time of listing. Cleaned. Accuracy not tested. Water resistance not guaranteed. A refined and historically important Seiko — the King Quartz stands as a symbol of Japan’s mastery of precision and design in the late 1970s.
