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.



The origin of Orient Watch Company dates back to 1901 when Shogoro Yoshida opened a wholesale shop called “Yoshida Watch Shop” in Ueno, Taito, Tokyo, Japan. Yoshida Watch Shop was successful, selling imported pocketwatches. In 1912, Yoshida expanded his business and began producing gold wristwatch cases. In 1920, Toyo Tokei Manufacturing was established, originally producing table clocks and gauges. It was not until 1934 that Toyo Tokei Manufacturing started the production of wristwatches. In 1936, the Hino factory was built in Hino, Tokyo, Japan. For several years, Toyo Tokei Manufacturing boomed at the Hino factory. However, affected by the poor Japanese economy after World War II, the company shut down in 1949.

After Toyo Tokei Manufacturing was shut down, Yoshida’s wristwatch manufacturing company was reborn in 1950, founded under the name Tama Keiki Company. Tama Keiki Co. continued manufacturing watches at the Hino factory. In 1951, Tama Keiki Co. changed its name to Orient Watch Company, Limited (オリエント時計株式会社, Oriento Tokei Kabushikigaisha), and in the same year the first Orient Star went on sale. Orient Watch was able to expand their visibility overseas after a memorandum trade agreement with China in 1955. The Royal Orient went on sale in 1960. Other important watches in the company’s history include the “Dynamic” in 1956, “Grand Prix 100” in 1964, “Fineness” (the world’s thinnest automatic wristwatch with day and date calendar function for its time) in 1967, and the “Tenbeat” in 1970.

In 2003, the Orient Technical Center (OTC) was established and the assembly of luxury watches began in Ugo, Ogachi, Akita, Japan. In 2004, the high-precision caliber 88700 movement went on sale via the Royal Orient watch line. In 2005, Orient Star Retro-Future collection was launched. In 2010, Orient Watch Co. celebrated its 60th anniversary with a limited edition model.

In 2001 Seiko Epson (one of three core companies of the Seiko Group) became the majority shareholder (52%) of the company. Orient Watch became a wholly owned subsidiary of Epson in 2009. After transferring its business to Epson, the company exists as a dormant company now. Epson Sales Japan Corporation markets the Orient watches, while Akita Epson Corporation manufactures them.




The Avant-garde Skeleton, with its modern stylish design is an evolution of the Classic Skeleton. The dial consists of two openwork plates superimposed to show depth with a three-dimensional effect. A honeycomb pattern below and a gear motif on top emphasise the mechanical features of the watch. The Avant-garde Skeleton has refined the exhibition of the mechanical movement unique to ORIENT STAR. Each part of the display can be read easily at a glance, not just the hour and minute hands and indices, but also the power reserve indicator at 12 o’clock and the small second hand at 6 o’clock. Even with the skeletonisation, high legibility is achieved due to the complimentary colour scheme used on the calculated open works on the dial.
