About ORIENT RA-AK0405Y
Orient Watch is a Japanese watch brand owned by Seiko Epson. Established as an independent company in 1950, it became a functional subsidiary of Epson in 2009 before being fully integrated into the company in 2017.
Until it was absorbed into Epson, the Orient Watch Company had primarily marketed mechanical watches (self-winding & hand-winding), but also produced quartz, light-powered (solar) and radio-controlled models. Outside of the main business, the company produced some moving parts and electronic components that were then assembled into Seiko Epson’s electronic devices.
Currently, Akita Epson Corporation (formally Akita Orient Precision Instruments Co., Ltd.), a group company of Epson, manufactures all of the Orient movements in-house in Yuzawa, Akita, Japan.
