5626-5050 — King Seiko Vanac

King Seiko Vanac

King Seiko's flamboyant 1970s sport-luxury escape from conservative dress design, defined by angular bezel-less cases, faceted gemstone-like crystals, and bold gradient dials in blue, green, bronze, and purple — Japan's answer to the Royal Oak era. Produced for only two years by both factories (Suwa's 5626 and Daini's 5246/5256 calibers) across a surprisingly large family of case shapes. Because the faceted crystals scratch easily, pristine originals are exceptionally rare; Seiko revived the name (as an acronym) in 2025.
