Seiko Group

is a Japanese corporate group consisting of three core companies Seiko Holdings Corp. (Seiko), Seiko Instruments Inc. (SII) and Seiko Epson Corp (Epson). They were independent companies linked together by the common thread of timepiece technology. Although they have some common shareholders including the key members of the Hattori family, the three companies in the Seiko Group are not affiliated. They are managed and operated completely independently. Epson has established its own brand image and rarely uses "Seiko."
