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 expand 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., Ltd. continued manufacturing watches at the Hino Factory. Just one year later, in 1951, Tama Keiki Co., Ltd. changed its name to Orient Watch Co., Ltd., 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 subsequently 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.
