Orient watch spans as far back as 1950. In 2017, Orient officially became part of Seiko Epson Corporation. Akita Epson Corporation is part Seiko Epson and manufactures all current Orient movements in-house in Yuzawa, Akita, Japan.
Unlike Seiko, Orient is not as transparent when it comes to the technical details of their movements. Epson does not even list mechanical movements in their catalog.
