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 color is ivy green, the accent color of the regimental ties that decorated the Ivy League look. The gold-colored seconds hand adds a traditional touch, while the Lumibrite on the hour hand, minute hand, and indexes has a patinated appearance that harmonizes with the dial.
