Seiko is a Japanese company that manufactures and sells watches, clocks, electronic devices, semiconductors and optical products. The company was founded in 1881, when Kintaro Hattori opened a watch and jewelry shop called "K. Hattori" in the Ginza area of Tokyo, Japan. Eleven years later, in 1892, he began to produce clocks under the name Seikosha, meaning roughly "House of Exquisite Workmanship". The first watches produced under the Seiko brand appeared in 1924. In 1969, Seiko introduced the Astron, the world's first production quartz watch. Seiko is perhaps best known for its wristwatches, all of which were at one time produced entirely in-house.
