Ivy style originated on the East Coast of the United States in the 1950s and developed uniquely in Japan in the 1960s, when King Seiko was born. The dial is burgundy, a color favored for the rugby shirts and swing tops that accentuate the Ivy look in a unique way. The gold seconds hand adds a traditional accent, while the hour hand, minute hand, and indexes feature Lumibrite with a patinated appearance that harmonizes with the dial.
