Our full-scale watch manufacturing goes back to 1937, when Daini Seikosha (now Seiko Instruments Inc.) was established as a company specializing in watch manufacturing after the launch of the Laurel in 1913. Headquartered in Kameido, Tokyo, Seiko has been leading the Japanese watch industry since its dawn. In 1967, Seiko entered the Swiss Observatoire Cantonal de Neuchâtel competition in timepiece accuracy and became a high-ranking winner, enabling us to show our technological capabilities to the world. In 1970, Morioka Seiko Instruments Inc. was opened in Shizukuishi as a major watch manufacturing base, and the company began full-scale production of quartz watches in the 1980s. In 2020, the watch business of Seiko Instruments Inc. was transferred and integrated to become a subsidiary of Seiko Watch Corporation. In the same year, to meet the ever-increasing need for luxury mechanical watches around the world, the company has opened Grand Seiko Studio Shizukuishi.
