King Seiko VANAC

King Seiko VANAC is a line of automatic watches produced in the early 1970s, notable for its distinctive and unconventional designs.
All models were paired with metal bracelets and featured faceted crystals that created intriguing plays of light on dials available in various colors.

The cases, in all kinds of shapes, were carefully finished, and the movements were also of high quality, as these watches were positioned at the top of the King Seiko selection.
Despite the relatively short production period, more than 50 different references are documented in the catalogs of that era.
