History: The Seiko "4206" mechanism is designed for Ladies' watches. It measures about 18mm in diameter. It uses a ball bearing quarter-arc rotor and can be hand-wound.

There are a large number of functions in this mechanism. In addition to the typical hours, minutes and seconds, it can also display the date and bilingual weekday. Both day/date functions can be quickly set in the middle crown position. The Seiko 4206B has got seventeen jewels, an excenter winding mechanism and a Glucydur balance, which is secured in two inhouse Diashock absorbers.

Info: Seiko Holdings Corporation (セイコーホールディングス株式会社 Seikō Hōrudingusu Kabushiki-gaisha), commonly known as Seiko (/ˈseɪkoʊ/ SAY-koh), is a Japanese holding company that has subsidiaries which manufactures and sells watches, clocks, electronic devices, semiconductors, jewelries, and optical products.

The company was founded in 1881, when Kintarō Hattori opened a watch and jewelry shop called "K. Hattori" (服部時計店 Hattori Tokeiten) in the Ginza area of Tokyo, Japan. Eleven years later, in 1892, he began to produce clocks under the name Seikosha (精工舎 Seikōsha), meaning roughly "House of Exquisite Workmanship". According to Seiko's official company history, titled "A Journey In Time: The Remarkable Story of Seiko" (2003), Seiko is a Japanese word meaning "exquisite" or "success" ("exquisite" is usually written 精巧 from Chinese jīngqiǎo, while the meaning "success" is usually written 成功 from Chinese chénggōng).
