Citizen is a Japanese company which still exists (2015). It produces watches, clocks, electronic devices and has several other activities. At some time its portfolio included the production of shutters.

History[edit | edit source]

The company was founded in 1918 as Shōkōsha Tokei Kenkyūjo (尚工舎時計研究所, meaning Shōkōsha Watch Research Institute) and became Citizen Tokei K.K. (シチズン時計㈱, officially translated as Citizen Watch Co., Ltd.).[1] It started the production of camera shutters in 1953, as a result of a cooperation with Chiyoda Kōgaku for the shutter of the Minoltaflex III and Minoltacord.[2] It notably made the Optiper HS shutter of the Minolta V2 and Minolta V3. The camera shutter activity was dropped at the beginning of the 1970s.[3]
