MECHANICAL

The "chronometer standard" stipulated by the Swiss Official Chronometer Testing Institute (COSC), which is famous as one of the standards for measuring the accuracy of a movement. Although it is a standard adopted by many watch brands, Grand Seiko watches, including the 9S Mechanical, do not have a "chronometer" description. This is because Grand Seiko has established its own precision standard "GS standard" that exceeds the chronometer standard.
In addition, there is a "GSS (Grand Seiko Special) standard" that exceeds the GS standard for mechanical watches. Watches conforming to the GSS standard, which boasts high accuracy of +4 seconds to -2 seconds average daily static accuracy, are marked with the word "SPECIAL" on the dial.

Grand Seiko mechanicals are more than just precision. We have developed models equipped with a GMT function that shows the second time zone, a high-beat function with excellent stability, a power reserve display, an instantaneous date advance mechanism, etc., and are also excellent in functionality.
One of the attractions is the good balance of the world's top-level precision and functionality, as well as the simple and sophisticated design that has been stripped of waste. The calm appearance of a brand born in Japan is popular among enthusiasts who seek high-spec watches.
