Seiko

, commonly known as Seiko ( , ), is a Japanese maker of watches, clocks, electronic devices, and semiconductors. Founded in 1881¹ by Kintarō Hattori in Tokyo, Seiko introduced the world's first commercial quartz wristwatch in 1969. Seiko is widely known for its wristwatches. Seiko and Rolex are the only two watch companies considered to be vertically integrated. Seiko is able to design and develop all the components of a watch, as well as assemble, adjust, inspect and ship them in-house. Seiko's mechanical watches consist of approximately 200 parts, and the company has the technology and production facilities to design and manufacture all of these parts internally. The company was incorporated (K. Hattori & Co., Ltd.) in 1917 and renamed Hattori Seiko Co., Ltd. in 1983 and Seiko Corporation in 1997. After reconstructing and creating its operating subsidiaries (such as Seiko Watch Corporation and Seiko Clock Inc.), it became a holding company in 2001 and was renamed Seiko Holdings Corporation on July 1, 2007. Seiko Holdings Corporation was renamed Seiko Group Corporation as of October 1, 2022. Seiko watches were originally produced by two Hattori family companies (not subsidiaries of K. Hattori & Co); one was Daini Seikosha Co. (now known as Seiko Instruments Inc., a subsidiary of Seiko Holdings since 2009) and the other was Suwa Seikosha Co.…

(now known as Seiko Epson Corporation, an independent publicly traded company). Having two companies both producing the same brand of watch enabled Seiko to improve technology through competition and hedge risk. It also reduced risk of production problems, since one company can increase production in the case of decreased production in the other parties. Seiko remains as one of the world's most recognised watchmaking brands. In Ginza, where the company was founded, there are several Seiko-related facilities in addition to Seiko House Ginza, including the Seiko Museum and Seiko Dream Square. Several Seiko boutiques and department stores in the area frequently offer Ginza-exclusive models.

History

Seiko Group

Hattori Tokeiten (K. Hattori & Co., currently Seiko Group Corporation) was one of the three principal companies of the former Seiko Group. The group was mainly composed of Hattori Tokeiten (K. Hattori), Daini Seikosha (currently Seiko Instruments Inc., SII), and Suwa Seikosha (currently Seiko Epson Corporation, Epson). Although they shared activities in the manufacturing and marketing of clocks and watches, the three companies were not formally affiliated as parent and subsidiary, nor as sibling companies under the Seiko Group; each was managed and operated independently, despite having some common shareholders, including key members of the Hattori family (posterity of Kintarō Hattori). Manufacturing was handled by three "Seikosha": Seikosha, the factory division of Hattori Tokeiten (K. Hattori), and two separate companies, Daini Seikosha and Suwa Seikosha. While there were no direct capital links among the three companies, they were connected through personal networks, centered around Hattori Tokeiten (K. Hattori), which managed sales.

Manufacturing sites

Seiko watches and their components are manufactured in Japan and several other countries in Asia. In Japan, watches are produced at Morioka Seiko Instruments, Tono Seiko, and Ninohe Seiko in Iwate Prefecture, as well as at the Seiko Epson's Shiojiri facility in Nagano Prefecture. Morioka Seiko Instruments is a subsidiary of Seiko Watch Corporation, while Tono Seiko and Ninohe Seiko are subsidiaries of Morioka Seiko Instruments. Grand Seiko mechanical watches are made at Morioka Seiko Instruments' Grand Seiko Studio Shizukuishi, while quartz and Spring Drive watches are produced at the Shinshu Watch Studio within Epson's Shiojiri facility. The highest-end Grand Seiko Masterpiece Collection is produced in limited quantities: Spring Drive models at Epson's Micro Artist Studio in Shiojiri, and mechanical models at Atelier Ginza, located on the 7th floor of Seiko House Ginza in Tokyo. The Micro Artist Studio also manufactures Credor's high-complication watches. Additionally, Orient brand watches, owned by Epson, are manufactured at Epson's facility in Akita Prefecture. Seiko has manufacturing facilities for watch parts and movements in Singapore, Malaysia, and China. In the late 1990s, the company transferred half of its movement production to a subsidiary in Singapore. Since the late 2010s, certain plastic component molding processes have been consolidated in China, while some metal processing operations have been consolidated in Malaysia. In 2020, these overseas manufacturing operations were reorganized as subsidiaries under Seiko Watch Corporation.

Credor

Credor is Seiko's highest-end brand alongside Grand Seiko. Seiko positions Grand Seiko as watches for everyday use, while Credor is intended for special occasions. The brand name is derived from the French words Crête d'Or, meaning "Crest (or Pinnacle) of Gold." Its logo symbolizes the peak of a mountain. As of 2026, the brand philosophy is "The Creativity of Artisans". Credor was established in 1974¹ as a low-volume production line specializing in watches made with precious metals such as gold and platinum. In 2019, it was reorganized as an independent brand, like Grand Seiko, separate from Seiko's main lineup. As of 2022, Credor remains primarily a domestic (Japanese) brand with limited international distribution. Between 2021 and 2022, Seiko determined that Credor's product range and distribution network had become excessively broad and risked undermining its brand identity, and it subsequently revised its marketing with a more carefully selected lineup. In 2026, Credor exhibited at Watches and Wonders for the first time, marking its debut at an international trade fair as it seeks to expand its presence overseas. As of May 2026, there is a notable difference in the brand's lineup between Japan and international markets: the official Japanese website lists 77 models, whereas the English-language global website lists only 15. Credor depends more on hand craftsmanship than Grand Seiko, making it more difficult to increase production. During Japan's economic bubble in the late 1980s and early 1990s, high-end jeweled watches priced over 10 million yen sold well, and Credor's jeweled watches experienced a golden era. In the mid-1980s, Credor's sales in the Japanese domestic market were approximately ten times those of Grand Seiko. Since the 1990s, in addition to quartz jeweled watches, Seiko began incorporating mechanical watches into the Credor line, featuring intricate engravings based on traditional Japanese aesthetics. In 1996, the brand released its first skeleton watch, the GBBD998, which featured the ultra-thin 1.98 mm Caliber 6899 and a caliber engraved with motifs of swaying bamboo and chrysanthemums. In 2000, Seiko established the Micro Artist Studio at Epson's facility in Shiojiri, Nagano, to begin producing haute horlogerie, which refers to high-end, artisanal Spring Drive watches, under the Credor name. Notable creations by the studio include the Credor Node Spring Drive Sonnerie (2006), Credor Node Eichi (2008), Credor Node Spring Drive Minute Repeater (2011), and Credor Eichi II (2014). Because Seiko had largely lost its capacity for high-end mechanical watchmaking by the late 1990s due to the quartz revolution, the release of the Spring Drive Sonnerie only six years after the studio's founding surprised many watch journalists. Credor is also known for its artistic watches decorated with traditional Japanese lacquer techniques such as maki-e, raden, kirikane (gold leaf cutting), and zōgan (metal inlay). In 1987, Credor released its first pocket watch featuring lacquer decoration. In 2016, the brand launched the Fugaku Tourbillon, the first Seiko watch with a tourbillon, priced at 50 million yen, featuring a dial adorned with Hokusai's The Great Wave off Kanagawa rendered in engraving and lacquer art. In 2025, Credor released a new Goldfeather Tourbillon priced at 25.3 million yen, featuring a newly developed caliber that succeeds the one used in the Fugaku. The watch is adorned with engravings and urushi lacquer art depicting birds and feathers.
