When Kintaro Hattori founded his company in 1881, he was just 21 years old. During his fifty years at the helm, Seiko became the leading watch company in Japan, with its own design and production facilities. This achievement was a direct result of his single-minded vision that Seiko should always be “one step ahead of the rest”.
