Seikos history began in 1881 when Kintaro Hattori established the K. Hattori retail and repair store. In 1892 Seikosha was established making wall clocks. 1895 saw the production of their first pocket watch. 1913 saw the launch of their first wristwatch, the Laurel. In 1924, the first Seiko was manufactured. Daini Seikosha (now Seiko Instruments Inc.) was established in 1937. Seiko was listed on the Tokyo Stock Exchange in 1949. The Suwa factory became independent and formed Suwa Seikosha Co., Ltd. (now Seiko Epson Corporation in 1959). In 1956, Seiko launched Marvel as their first true in-house made watch, and they continued to make this watch until 1959. Japan’s first chronograph watch was introduced for the 1964 Tokyo Olympics; it was called the Seiko Crown Chronograph, a monopusher. Not stopping there, Seiko launched Japan's first true divers watch, the Seiko Diver’s 150M fitted with the automatic Caliber 6217, which later was given the nickname “62MAS” by collectors. The company name was changed to the Seiko Corporation in 1990. Innovation at Seiko continues today with GPS Solar watches.
