► ARCHIVE FILE: SEIKO — BRAND HISTORY
Seiko begins with Kintaro Hattori, who opened a shop selling and repairing clocks in Tokyo's Ginza district in 1881, at the age of twenty-one. He founded the Seikosha factory in 1892 to manufacture wall clocks, built Japan's first wristwatch, the Laurel, in 1913, and put the Seiko name on a dial for the first time in 1924. By mid-century his successors ran one of the most vertically integrated watch companies on earth, making everything from hairsprings to cases under its own roof.
