Seikosha (精工舎, Seikōsha) is a Japanese company that manufactured shutters. It was founded as the manufacturing branch of Hattori Tokei-ten, to make clocks and watches. It began the production of camera shutters in 1930, but volume production did not start until 1933.[1]
The camera shutter branch of Seikōsha became Seikō Kōki (セイコー光機) in 1963. It was merged back into Seikosha in 1986, thus becoming Seiko Precision Inc. (セイコープレシジョン株式会社).[2] This company still exists today (2006) and still makes camera components.
