King Seiko Special Edition. Introduced in 1961 and in production until 1975,King Seiko became one of Seiko’s most technically innovative and stylish brands, noted for its sleek, dignified angularity. A newly developed slim case and the thin 6R31 automatic movement, with a frequency of 21,600 vibrations per hour, a power reserve of approximately 70 hours, and manual winding capability, make this Special Edition model exceptionally slender and elegant, with a case thickness of only 10.33 mm. In a new purple shade, “Tenjin-fuji violet,” the dial evokes the wisteria that bloom in the Kameido Tenjin Shrine in Kameido, Japan, birthplace of the original King Seiko. A major tourist attraction, founded in 1661, the shrine, with its bridge and flowers, was the subject of famed Ukiyoe artist Hiroshige Utagawa’s “In the Kameido Tenjin Shrine Compound (Kemeido Tenjin Keidai),” said to have influenced Impressionist master Claude Monet.
