Seiko mantel clocks, founded in 1881, is committed to the art and science of time. The story of Seiko mantel clocks began when Kintaro Hattori opened a clock repair store in central Tokyo at the age of 22. Just eleven years later, the company made its first mantel clock and the rest is history. Other ancient timekeeping devices include the candle clock, used in ancient China, ancient Japan, England and Mesopotamia; the timestick, widely used in Persia, India and Tibet, as well as some parts of Europe; and the hourglass, which functioned similarly to a water clock.
