Every trade that managers of Seiko Corporation disclose to EDINET (Japan FSA) is tracked on this page. The company sits in the Industrials sector and is based in Shimizu-ku, Japan. It was founded in 1939. 2 insiders have disclosed 5 filings since 26 October 2025.
The filings describe grants, exercises and other transfers rather than trades on the open market. Such operations are usually part of compensation schedules, which makes them a weaker signal than an open-market trade.
